Suppose I have two 3.6 and 10.75.
10.75 is not divisible by 3.6 but 10.80 is perfectly divisible (difference being 0.05).
How can I compute this difference (0.05) as my output by giving 3.6 and 10.75 as inputs?

Try this:
numerator = 10.75;
denominator = 3.6;
lowerRemainder = rem(numerator, denominator)
upperRemainder = denominator - lowerRemainder
Results in command window:
lowerRemainder =
3.55
upperRemainder =
0.0500000000000003
So, you're probably wondering why it's not exactly 0.05. If so, you need to read and understand this FAQ section: http://matlab.wikia.com/wiki/FAQ#Why_is_0.3_-_0.2_-_0.1_.28or_similar.29_not_equal_to_zero.3F
