How do we not have infinite number of bands available if we just use more decimals? Ie, 99.3 FM becomes 99.35, 99.353, and so on… how “close” can stations be?
How do some stations interference with each other while being far away numerical, but other stations are a decimal point away with no interference?
I’m doing HAM radio study for no reason other than it sounds neat and it’s cool to have a technical skill, but I’m having trouble wrapping my head around how we can’t just subdivide a limited band X number of times to fit more people in without interference.

It is the accuracy of the radios picking up the transmission. Signals are broadcast over a band of frequencies plus or minus 0.1 GHz for example. This is to ensure that the inaccuracies in the radios can still pick it up. Yes in a perfect world you can have infinite but precision is poor.
