I'm not even going to count

We don't use -illion for numbers like this (except as a joke) We use "million, billion and trillion" for some very large amounts (usually large amounts of money). Higher terms like "quadrillion" etc are very rare.

For numbers that are too large to write never occur in normal converstation. In a scientific or mathematical context they might occur, in which case you should use standard index form 1×10¹⁰⁰ for one followed by 100 zeros.

There is the joke word "googol" for this. It is a joke word and nothing more.

Okay, I did count, and there are 860 zeros = 2+ (285×3 + 3)

So just for the joke, that is one-hundred-ducentioctogintaquintillion
