It depends on the divisor (what number was doing the dividing). Some examples:

46 Remainder 0
To convert decimal to binary, divide the decimal number you want to convert by 2 and write down the remainder. Repeat this until the final result is zero. The remainders you wrote down, written from the last one you wrote to the first (so the opposite order from which you derived them) is the binary equivalent.So using this method with the number 23 we get:23/2 = 11 remainder 111/2 = 5 remainder 15/2 = 2 remainder 12/2 = 1 remainder 01/2 = 0 remainder 1So the binary equivalent is 10111
A decimal without a remainder is a whole number or integer.
Well, isn't that a happy little question! To write a remainder as a decimal, you simply divide the remainder by the divisor. This will give you a decimal representation of the remaining part. Just remember, there are no mistakes, just happy little accidents in math!
If you are given a sum with a remainder, for example, 17 / 5 = 3 remainder 2, then you can convert the number to a mixed number by putting the remainder as the numerator of the fraction, and the divisor as the denominator of the fraction. At this point, the fractional part of the sum can easily be turned into a decimal by dividing the numerator of the fraction by the denominator - therefore, 17 / 5 = 3 2/5 or 3.4.
