two hundred octillion

This one, I wouldn't have even touched.

I would have said a hundred gazillion and let it go at that.

Many.
It's not that tough. I got interested in this when I was a kid and my mom told me about the terms "trillion" and "quadrillion" and that she didn't know the ones beyond that. So I looked it up in our big dictionary and it has stuck with me since.
Each set of three digits, separated by commas, is another "-illion". The first, counting from the right, are the "hundreds", the next, to the left are the thousands. Then it's (in America)
million
billion
trillion
quintillion
sextillion
septillion
octillion
nonillion
decillion
and so on. You see the pattern.
Of course, it gets ridiculous at some point, especially since hardly anyone ever uses these terms beyond "trillion" or so. That's why in science we use exponential notation, which can simply handle a number of virtually any size.
Incidentally, the number "1" followed by one hundred zeros (10^100) is a "google", believe it or not. Ten raised to the google power is a "googolplex". These are also trivial, useless terms.

Almost nobody calls such large numbers by name, at least in English.

People who actually use such large numbers would probably read them as follows:
200,000,000,000,000,000,000,000,000,000 is "two times ten to the twenty-nine"
100,000,000,000,000,000 is "ten to the seventeen"
Incidentally, the number "1" followed by one hundred zeros (10[/nq]^100) is a
"google", believe it or not. Ten raised to the google power is a "googolplex". These are also trivial, useless terms.

No, 10^100 is a "googol." Google changed the spelling so they could trademark it.
