How can you divide decimals by whole numbers?

Answer 1

If you had 1/2 (0.5) of a Pizza left and wanted to share it equally with your friend you would share it so that each of you got 0.5 ÷ 2 of the whole pizza each.

To actually do this, using the "bus stop" [shelter] method of long/short division is the easiest:

Write the whole number divisor outside the bus stop and put the decimal dividend under the bus stop [shelter]. Place a decimal point in the quotient answer above the bus stop [shelter] ABOVE the decimal point in the dividend. Now do the long/short division as normal, ignoring the decimal points (except if there is a remainder extra zeros can be added onto the end of the dividend and the division continued until there is no remainder or the required degree of accuracy has been reached to allow an approximate, rounded, answer) . Finally read the quotient answer including the decimal point.
