In the previous section, we learned how to multiply decimal numbers. In this section, we will learn how to divide decimal numbers. First, we will divide using diagrams. Next, we will divide using number lines. Then, we will divide using long division. When dividing using long division, the divisor must first be turned into a whole number by moving the decimal point over to the right one or more spaces. Next, the decimal point in the dividend must be moved over to the right the same number of spaces. The decimal point in the answer will line up with the decimal point in the dividend.
