DIVISION LESSON 75 1. Divide 1282.56 by 76.8. Operation As the dividend is the product of the divisor 76.8)1282.56(16.7 and quotient, the number of decimal places in the 68. dividend should equal the number in the divisor 5145 and quotient taken together. 4608 Since there are two decimal places in the divi-5376 dend and one in the divisor, there must be the 5376 difference between livo and one, or one decimal place in the quotient. 2. Divide 136.318 by 3.185.

When the number of decimal places in the divisor exceeds the number in the dividend, we make them equal by annexing ciphers to the dividend. 6. Divide.054 by 28.8. Sometimes ciphers must be prefixed to the quotient figures in order to make the number of decimal places equal the excess of the number in the dividend over the number in the divisor.
