The Babylonians used a sexagesimal (base-60) number system and applied this to dividing space and time: they divided angles into 60 parts (degrees) and because exactly six angles of 60° form a complete circle, a full circle measures 360°.

Evidence Quote

because these people used the sexesimal system for the concept of numbers, which is a number system based on the number 60, they loved to divide different things into 60 parts...Since exactly six of these form a complete circle, we measure 6 * 60 or 360° in a circle.
