Check for whole number.

[Dasfaas]

hi, only at this a couple of weeks. im stuck with a problem in that i need the user to enter two numbers, and to then check if the second divides exactly into the first. if you wouldnt mind putting it as simply as possible, as i am still trying to get my head around this.
Thanks!
