Grace Caldelas: The rule is: Dad: divide Mom: multiply Sister: subtract Brother: bring down Rover: Repeat
in dividing decimals you never get a remainder and in dividing whole numbers you do. +++ More to the point perhaps, you are working in powers of 10 all the time.
If you are making use of long division method, the process of dividing a whole number is actually a subset of the process of dividing the decimals. While dividing both you may get a quotient with decimal places. Some exceptions to this do exist in case of whole numbers. Like when you are dividing 100 by 2, the quotient 50 has no decimal places.
By the time you advance to the point of dividing decimals, you don't use remainders any more.
because you can always add a 0 when using decimals
by dividing the numerator by the denominator
By dividing the numerator by the denominator
You multiplie the number you were dividing by with the answer.
