    Thanks BUT there is a problem in your demo from part one to part three. You are saying that the reminder can either be 0, 1, 2 or 3 which is true, then in the next phase you say, if remainder is 0 or 1 add 2 if the remainder is 3 or 4, substract 2 … that second statement does not make sense since you forget the possibility that the remainder is 2 and you have a remainder of 4 which according to the statement from phase one, it’s not possible. I assume you meant if the remainder is 2 or 3, substract two.
