Hi there anyone, was wondering if you can help?

I need to pull a users input in, ready for division
i have been using al, and the dos interupt 21h but this will only load one character at a time and the program needs to except numbers upto 255, so i need to buffer it some how, and check that the input is a number not characters, im a little confused how to do this?
