What is Division?
Division is an arithmetic operation that plays a crucial role in mathematics and everyday life. It involves dividing a number (the dividend) by another (the divisor) to find how many equal parts or groups can be formed.

If you are giving an overview of division to your kid, you may cite the following example.
Suppose Ryan has 20 apples. He wants to divide the apples between two of his friends equally. How many apples will each of them get?
Your kids can find the answer by following the division process.
The Formula for Division
To grasp the concept of division fully, it's crucial to familiarise your kid with its main components: the dividend, Divisor, quotient, and Remainder.
Let's break down these terms for a clearer understanding.
- Dividend: This is the number that is being divided. Ask your kid to think of it as the total amount of something you have. For example, 20 apples (as discussed above).
- Divisor: This is the number by which the dividend is divided. It represents how many groups or parts you want to divide the dividend into. For the question asked above, it is 2 as the apples will be divided between 2 friends.
- Quotient: This is the result of division. It tells us how many times the divisor fits into the dividend completely.
- Remainder: Sometimes, the divisor doesn't fit perfectly into the dividend, and you're left with something extra. This extra amount is called the Remainder.
When you divide a dividend by a divisor, you get a quotient, and sometimes, there's a remainder left. You can show this concept to your kid even Mathematically. Follow the formulas below.
Formula1: Dividend ÷ Divisor = Quotient
Formula 2: Dividend ÷ Divisor = Quotient with a remainder of Remainder
For example, when you divide 20 by 2, the quotient is 10, and the remainder is 0. Now, if we divide 15 by 2, the result will be 15 ÷ 2 = 7 with a remainder of 1.
How to Use a Division Calculator?
This is how you can ask your kid to use a Division Calculator to find the quotient and remainder:
Step 1: First, enter the dividend.
Step 2: Next, input the divisor.
Step 3: Click the calculate button.
Step 4: The division calculator will show the quotient and the Remainder (if any).
FAQS
The full formula for division is expressed as
Dividend = Divisor*Quotient + Remainder
For a practical example, consider dividing 22 by 7. The quotient is 3, and there is 1 as left over. So, the full expression of this division is 22 = 7*3+1.
A number is divisible by 11 if the alternating sum of its digits is 0 or divisible by 11. For example, the number 121 is divisible by 11 because the alternating sum (1 – 2 + 1) equals 0.
To solve a division problem on a division calculator online:
Input the Dividend: Start by typing the number you wish to divide. For instance, entering “250”.
Select Division: Press the division symbol (÷ or /).
Input the Divisor: Enter the number you are dividing by, such as “50”.
Get the Result: Press the equals button (=) to find the quotient. In this case, you would get 5 as 250 divided by 50 equals 5.
