Beat snap divisor
The Beat Snap Divisor is used to limit where notes can be placed so that they always fall on the beat. Moving the slider to the right increases the granularity of the notes, that is, more notes can be placed in the same measure.
Each of the settings put different colours of ticks on the Timelines. The ticks are as follows (for Standard, osu!taiko, and osu!catch):
osu!, osu!taiko and osu!catch

The 1/3 and 1/6 are special because it means your BPM is divisible by three, but this is rare.
Holding down the Alt button over the slider changes it to the distance spacing slider
