Thus, 8, 162.41 ÷ 10 = 816.241.
Notice that the divisor 10 is composed of one 0 and that the quotient 816.241 can be obtained from the
dividend 8,162.41 by moving the decimal point one place to the left.

Thus, 8, 162.41 ÷ 100 = 81.6241.
Notice that the divisor 100 is composed of two 0's and that the quotient 81.6241 can be obtained from the
dividend by moving the decimal point two places to the left.
Using these observations, we can suggest the following method for dividing decimal numbers by powers of
10.
