That's largely done by just weighting the top scores such that one or two spiked scores, while they would be the largest contributors aren't the sole contributors.

And while it is definitely possible for somebody who can AAA a 114 to continue to gain ranking as more songs at 112+ are added resulting in the kind of inflation you're discussing, the MAIN reason there's division inflation is just that one player's score going up does not result in another player's score going down, so naturally over time, the top end gets larger and larger.

Whether that justifies making more divisions is a different question, but it's inevitable that more and more people will be in the current top division both over time, and as more high difficulty songs are added.
