Dividing whole numbers not exceeding 10 000 000

Example

Divide: 3,850,500 ÷ 150

Steps:

1. Divide 38 by 150. 38 is not sufficient for this division. Therefore, take 385 and divide it by 150. Find a number which when multiplied by 150 gives 385 or a whole number closer to 385. Multiply 2 by 150 to get 300. This is the required whole number. (When you multiply it by 3 you get 450 which is greater than 385) Write 2 above the ten thousands position in the answer, then write 300 below 385. Subtract to get 85. Drop down 0 to get 850.

2. Divide 850 by 150. Find a number which when multiplied by 150 gives 850 or a whole number closer to 850. The number is 5, that is 150 × 5 = 750. Write 5 in the place of the answer at the thousands place to the right of 2. Write 750 below 850 and subtract to get 100. Drop down 5 to get 1,005.

3. Divide 1,005 by 150. Find a number which when multiplied by 150 gives 1,005 or a whole number closer to 1,005. This number is 6, that is 6 × 150 = 900. Write 6 above hundreds in the place of the answer and 900 below 1,005, then subtract. You remain with 105. Drop 0 in order to get 1,050.

4. Divide 1,050 by 150. Find a number which when multiplied by 150 gives 1,050 or a whole number closer to 1,005. This number is 7, whereby 7 × 150 = 1,050. Write 7 above tens in the position of the answer and write 1,050 below 1,050, then subtract to get 0. Drop down 0 in order to get 0.

5. Divide 0 by 150. Find a number when multiplied by 150 you will get 0. This number is 0. Write 0 above the ones place in the position of the answer, and write 0 below 0. Subtract to get 0.

Therefore, 3,850,500 ÷ 150 = 25,670.
