To divide a decimal by a whole number, divide as you would for whole numbers; and place a decimal point in the answer so that it lines up with the decimal point in the dividend.
To divide a decimal number by a whole number: 1  Use Division or Long Division (ignoring the decimal point). 2  Then put the decimal point in the same spot as the dividend (the number being divided).he trick is to change the number we are dividing by to a whole number first, by shifting the decimal point of both numbers to the right: Now we are dividing by a whole number, and can continue as normal. It is safe to do this if we remember to shift the decimal point of both numbers the same number of places.
