Stepped Gradient Effect

King Mango

I'm looking for a way to break a gradient into a variable number of steps.
The effect I'm going for is a shale like flaky rock surface.
Right now I'm using a curve but that's less than elegant workflow-wise.
I'd like to be able to use a dynamic gradient and have the steps controlled by a stepped gradient that can be divided into the desired number of steps.
I went into pixel processor but that water is a little deep for me!
something like this:

there's a quantize node already - just use that?

thank you!

I use this simple math in pixel processor  for decades.  5 integer is how many  steps you want .   I think it works quicker.

ps. Well . default one looks  like doing same just with extra options.

it does yeah - it might offset the values slightly to get the full range more reliably
