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.

Humans can hear a range of frequencies, say 20Hz to 20kHz, and you need to record up to twice the maximum of that to get full reproduction. Then you put that 40kHz band of frequencies on top of a given carrier radio frequency, and that is the band that is occupied by your broadcast (sort of). The quoted frequency is basically the middle of a band where the deviation from nominal tells your radio what sound to play at a given moment. If another band overlaps then they will interfere.
