Well the way it was asked made it sound like it was a lab for a programming course in college (or at the very least you had to assume that there wasn't something out there that already did this). so yeah you sort of have to re-invent the wheel for that sort of thing

Now write it in Intercal!

I thought real programers wrote in assembly.

It's easy since there are some basic patterns.

First, groups the digits of the number into the groups of three as we do with commas when writing the number out. Each group of the is written as "{blah-blah-blah} {billion|million|thousand|[nothing]|etc}" with a separator between groups. This lets you write out numbers as big as you have the names of the groups for.

For the groups of three digits themselves, they break down into "{blah} hundred {blah-blah}". So the hundreds digit is taken care of. Then you just need to do all the special case logic to write out the tens and ones digit for the group.

There are a few other special cases to suss out like skipping groups of "000", but it shouldn't be too bad.

I used to be a Perl programmer, then I took a Python to the knee!
