Dividing Decimals by Decimals

Students learn to divide a decimal by a decimal by first multiplying both decimals by the power of 10 that changes the second decimal to a whole number. For example, to divide 0.16 by 0.8, first multiply both decimals by 10, to get 1.6 8. Next, divide the decimal by the whole number in the same way that one would divide a whole number by a whole number (using long division). However, at the end of the problem, the decimal point is brought straight up from the decimal that is inside the division symbol to the answer that is written on top of the division symbol.
