Arrow-Puffin-3_Semester-1 Maths 181Example 3: Divide 1875 by 15.%u2022 Arrange the numbers as shown.%u2022 The first digit is 1. 1 < 15. So we consider next digit i.e. 8. Divide 18 by 15; 15 x 1 = 15. Write 1 in the hundreds place as quotient. Write 15 below 18 and subtract.%u2022 Bring down 7. It is now 37. Divide 37 by 15 i.e. 15 x 2 = 30. Write 2 in the tens place as quotient. Write 30 below 37 and subtract.%u2022 Bring down 5 ones. We have the number 75. Divide 75 by 15 i.e. 15 x 5 = 75. Write 5 in the ones place as quotient. Write 75 below 75 and subtract. The quotient is 125. 1875 + 15 = 125.

Write 15 under 18 and subtract.%u2022 Bring down 7. Next number to be divided by 15 is 37. Check the table again.15 x 2= 30. Write 30 under 37 and subtract.%u2022 Bring down 5. Next number to be divided by 15 is 75. Check the table again 15 x 5 = 75. Write 75 under 75 and subtract.15 x 1 = 1515 x 2 = 3015 x 3 = 4515 x 4 = 6015 x 5 = 75
