I have always found binary coded decimal (BCD) the simplest for this
purpose, as it is directly extensible to any length, with only a few
lines of code. Please see any (low-level; i.e., machine-code) book
on arithmetic algorithms. They may not teach BCD anymore, but back
in the day... (i.e., Earth still cooling, ...).

You probably can find a long list of "ACM Programming Contest" long
math algorithms. At least when I was on our College's team, the ACM
loved to put problems involving long math in the mix. As far as I
know every team had ready-to-go source for long-math operations just
for that reason. We only got burned by not being ready for this type
of situation once before we made sure we did.
