Divide circle with 32 verticles into 12 equal parts

i made like my own iq test in blender(3d program), trying to get a circle into 12 slices.
is this even possible?

so 360/12 = 30 degrees each

32/4= 8

however i would want 9, then I could split it up into 3 slices per each quarter of the circle.

With 8 I would get a decimal number, and that wouldn't work.

So am I just being retarded or is this not possible?

360/12 = 30 degrees each. This is correct
each of the 32 sectors have 360/32 = 11.25 degrees
How many of this you will combine to get 30 degree = 30/11.25 = 40/15

So it means you should first divide each of 32 sectors into 15 parts to get 480 parts of the circle. Each will be 11.25/15 = .75 degree. Then take 40 such parts, every time to get 12 equal parts of the circle.
