In division, the number called the dividend is divided by the divisor, and the result is called quotient.

Example :

Division without remainder

Example :

Step 1 : Start on the left. Check if first digit, 5, is bigger than the divisor 12. Since 5 is not, we need to take the next digit as well.

51 divided by 12 gives 4 as the quotient since 12 × 4 = 48.

Write 4 above 1.

Step 2 : Write the number 48 below 51.Subtract 48 from 51 to get a remainder of 3. Bring down the next digit, 6, and write it after 3.

Step 3 : Now repeat from Step 1. 36 divided by 12, gives 3. Write 3 above 6. Write the number 36 below 36. Subtract 36 from 36 to get a remainder of 0. Your answer is then 43.

Division with remainder

Example :

Step 1 : Start on the left. Check if first digit, 9, is bigger than the divisor 12. Since 9 is not, we need to take the next digit as well.

99 divided by 12 gives 8 as the quotient since 12 × 8 = 96.

Write 8 above 9.

Step 2 : Write the number 96 below 99. Subtract 96 from 99 to get a remainder of 3. Bring down the next digit, 3, and write it after 3.

Step 3 : Now repeat from Step 1. 33 divided by 12, gives 2. Write 2 above 3. Write the number 24 below 33. Subtract 24 from 33 to get a remainder of 9. Your answer is then 82 remainder 9.

TAKE NOTE:

For division, the divisor cannot be 0.

Example : 23 ÷ 0 is not permissible.
