ELI5: Why were revolvers created to generally have 6 shots?

It would make sense to have 5 or 10 considering we have a base 10 system, but it's not. Was there any historic reasoning behind this number specifically or was it only a random choice that stuck for the rest of production?

Ease of design, mostly. If you stack 7 circles in as close a shape possible, you get an hexagon with 2 on top, 3 in the middle, and 2 at the bottom. Use the centre as a rotating part, and you get 6 holes in a symmetrical way, without having to do weird complicated math.
