You do it just like you do it on paper: one digit at a time, right to
left. The details depend on how the numbers are stored, of course.

If you look for solutions ready for use: There are libraries to handle
this, e.g. gmp, cln and possibly many more.

If you look for explanations: Handling large numbers should be done in
most university courses on computer algebra. There are books with just
that name explaining arithmetics on many different sets, and how it can
be implemented.
