Exercise 161

Divide this. (See Examples.)

Dividing Whole Numbers

To divide 1095 baseball cards evenly among 73 collectors, divide 1095 by 73 as follows.

Since 73 is larger than 1 or 10, but smaller than 109, begin by dividing 73 into 109. There is one 73 in 109, so place 1 over the digit 9 in the dividend as shown. Then multiply 1 and 73.

Subtract 73 from 109 to get 36. The next step is to bring down the 5 from the dividend, placing it next to the remainder 36. This gives the number 365. The divisor, 73, is then divided into 365 with a result of 5, which is placed to the right of the 1 in the quotient. Since 73 divides into 365 exactly 5 times, the final answer (quotient) is exactly 15.

Check the answer by multiplying.
