How do you divide a decimal by a whole number?

Back

To divide a decimal by a whole number, move the decimal point in the dividend (the number being divided) to the right until it becomes a whole number. Then, divide as you would with whole numbers and place the decimal point in the quotient (the result) directly above where it was in the dividend.
