The division is one of the four basic mathematical operations, the other three being addition, subtraction, and multiplication. In simple words, division can be defined as the splitting of a large group into smaller groups such that every group will have an equal number of items. It is an operation used for equal grouping and equal sharing in math. Let us learn about division operation in math in detail in this article.

What is Division?
The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items. For example, for a sports event, if 30 students need to be divided into groups of 5 students, then how many total groups will be formed? Such problems can be solved easily using the division operation. Here we need to divide 30 by 5. The result will be 30 ÷ 5 = 6. So, there will be 6 groups of 5 students in each. You can verify this value by multiplying 6 and 5, which will give you the original number, 30.
The division is the process of repetitive subtraction. It is the inverse of the multiplication operation. It is defined as the act of forming equal groups. While dividing numbers, we break down a larger number into smaller numbers such that the multiplication of those smaller numbers will be equal to the larger number taken. For example, 4 ÷ 2 = 2. This can be written as a multiplication fact as 2 × 2 = 4.
The division is denoted by a mathematical symbol that consists of a small horizontal line with a dot each above and below the line. There are two basic division symbols that represent the division of two numbers. They are ÷ and /. For example, 4 ÷ 2 = 2, and 4/2 = 2.
Parts of Division
Parts of division mean the name of the terms associated with the division process. There are four parts of the division, which are dividend, divisor, quotient, and remainder. Let us look at an example of division given below and understand the meanings of these four parts of the division.
Here, when we divide 105 by 8, we get the values of a divisor, dividend, quotient, and remainder. Look at the table below to understand the meaning of these terms.
|Dividend||The number that is to be divided||105|
|Divisor||The number of equal groups that are to be made, or the number by which we divide the dividend||8|
|Quotient||The value/answer obtained after performing the division||13|
|Remainder||The remaining or left out value that is not a part of any group||1|
In the above image, it is written that "Dividend = Divisor × Quotient + Remainder". This equation satisfies the above values but will it be satisfying for values of dividend, divisor, quotient, and the remainder in every division? Let's find out.
The division algorithm is an equation that forms a relationship between all four parts of the division. In any division fact, the product of divisor and quotient added to the remainder is always equal to the value of the dividend. Thus, the general formula of division is: Dividend = (Divisor × Quotient) + Remainder. This is known as the division algorithm.
The above formula helps us to verify the values of quotient and remainder obtained after performing division. We can substitute the values of the quotient, remainder, and divisor in the above equation and check whether the result is the same as dividend or not. If we get the dividend, it means we have done the steps of division correctly. If not, it means there is an error in our calculations that we need to rectify. Let us take one example and see if it satisfies the above division algorithm or not. Divide 17 by 3. 17 divided by 3 will give us 5 as the quotient and 2 as the remainder.
Dividend = (Divisor × Quotient) + Remainder
17 = (3 × 5) + 2
17 = 15 + 2
17 = 17
How to do Division?
One-digit division can be done using multiplication tables. For example, to solve 24 ÷ 6, we just need to see what we need to multiply by 6 to get 24 as the answer. Clearly, 6 × 4 = 24, therefore 24 ÷ 6 = 4. When it comes to the division of numbers with greater numbers, then we can use the long division method. Let us take the example of 65 divided by 5 to understand it. Follow the steps below to learn how to do division:
- Step 1: Draw the division symbol ⟌ and write divisor (5) on its left side and dividend (65) enclosed under this symbol.
- Step 2: Take the first digit of the dividend from the left (6). Check if this digit is greater than or equal to the divisor. [If the first digit of the dividend is less than the divisor, then we consider the first two digits of the dividend]
- Step 3: Then divide it by the divisor and write the answer on top as the quotient. Here, the quotient of 6 ÷ 5 is 1.
- Step 4: Subtract the product of the divisor and the digit written in the quotient (5 × 1) from the first digit of the dividend and write the difference below. Here, the difference is 6 - 5 = 1.
- Step 5: Bring down the next digit of the dividend (if present). The next digit in the dividend is 5.
- Step 6: Repeat the same process until you get the remainder, less than the divisor.
Look at the image given below showing the above steps of division.
Division with Remainders
It is not always mandatory to have 0 as the remainder. If the dividend is not a multiple of the divisor, then we get a non-zero remainder. When we get a non-zero remainder while dividing a number by another, it is known as a division with remainders. Let us take an example of distributing 9 balloons to 2 children equally such that both children will have an equal number of balloons with them. Is it possible to do that without getting a leftover?
Dividing 9 by 2 will give us 4 as the quotient and 1 as the remainder. We can make 2 groups having 4 balloons in each but 1 balloon will be left. Look at the image below showing division with remainders (9 ÷ 2).
Go ahead and try out the following division questions and observe whether you get a non-zero remainder or not: 63 ÷ 9, 76 ÷ 13, 89 ÷ 8, 34 ÷ 5, and 27 ÷ 3.
Properties of Division
Now let us look at some of the properties of division operation that will help you understand this operation even better. Listed below are a few properties of division:
- Division by 1: Any number divided by 1 results in the number itself. In other words, if divisor = 1, then dividend = quotient.
- Division by 0: The value of a number divided by 0 is not defined, i.e. n/0 = not defined, where n is any number.
- Division by itself: If we divide a number by itself, we will always get 1 as the answer. In other words, if dividend = divisor, then quotient = 1.
- Division of 0 by any number: 0 divided by any number always results in 0. Some examples are 0 ÷ 4 = 0, 0 ÷ 9 = 0, 0 ÷ 5754 = 0, etc.
- Division by 10: If we divide a number by 10, then the digit at the ones place will always be the remainder and the remaining digits on the left will be the quotient. For example, 579 ÷ 10 = 57 R 9.
- Division by 100: If we divide a number by 100, then the number formed from the ones place and the tens place digits will always be the remainder and the remaining digits on the left will be the quotient. For example, 8709 ÷ 100 = 87 R 9.

FAQs on Division
What is Division in Math?
In maths, we have four basic arithmetic operations i.e., addition, subtraction, multiplication, and division. Amongst these four operations, the division is one of the major operations we use in our daily activities. It is the process of splitting a large group into equal smaller groups. For example, divide 25 by 5. Division fact for this example will be, 25 ÷ 5 = 5.
What are the Two Types of Division?
The division is split into two parts i.e., partitive and quotative models. Partitive is used when dividing a number into a known number of slots. For example, if we divide 4 into 2 slots, we can find out how many items will be in each slot. Quotative division is used when dividing a number into slots of a measured quantity. For example, when we divide 4 into slots of 2, we can determine how many slots can be created.
What are the Three Parts of Division?
The three main parts of division are dividend, quotient, and divisor. In addition to this, when the divisor is not a factor of the dividend, then we get a non-zero remainder which is the fourth part of the division.
What is Long Division Method?
The long division method is the most common method used to solve problems on division. In this process, the divisor is written outside the division symbol, while the dividend is placed within. The quotient is written above the overbar on top of the dividend.
What are the Steps of the Division?
The steps to do division are listed below:
- Step 1: Take the first digit of the dividend. Check if this digit is greater than or equal to the divisor.
- Step 2: Then divide it by the divisor and write the answer on top.
- Step 3: Subtract the result from the digit and write below.
- Step 4: Again, repeat the same process.
How do you Divide when the Divisor is Bigger Than the Dividend?
In this case of division, we can simply keep on adding zeros to the right of the dividend until it becomes appropriate to divide further. Furthermore, we can divide the quotient by the same powers of 10 for the final answer once we get the division done correctly.
How to Divide Decimals?
Dividing decimals is also as easy as dividing any other numbers. All you need to do is multiply the decimal with powers of ten till you get an integer. Then you can carry out the normal division process. Once you get your final answer, make sure to divide it with the same powers of 10 that you divided earlier with.

What is the Division Symbol?
There are two symbols of division which are: ÷ and /. ÷ symbol is drawn by placing two small dots on the top and bottom of a small horizontal line. And, / sign is used mostly with fractions, ratios, and percentages.
Why Division by Zero is Undefined?
Division by zero is undefined because one cannot divide any number by zero. This is because when any number is multiplied to zero, the answer is 0. Now, think the reverse of it. 1/0 will have infinite value. We can not quantify this value in mathematics. Hence, the division of any number by zero is undefined.
