How Is Stoke's Drag Formula Derived Beyond Dimensional Analysis?

[ThinkerCorny]

I was looking for the derivation of stoke's drag
F=6πηrv
But I'm only getting the derivation by dimensional analysis.
Can anyone please provide it's real derivation?
I'll really appreciate it.

You mean e.g. this one ? (I googled 'stokes drag derivation' and this was on top).
