Is there an algorithm for drawing lines without fractions?

Question

assembler

I was able to figure out some kind of algorithm, in C ++ I made a rhyme of the necessary numbers there, in paint I built a line on them and it seemed to work.
I already thought, well, now it would be nice to transfer this to my OS (only BIOS interrupts, real time mode), and then I realized that ordinary registers work only with integers .. What should I do.
Also, are there any simple line drawing algorithms that do not encounter this problem?
PS: Do not judge strictly for the question, I'm just learning assembler.
