Can you show one example of a commercially produced general purpose CPU that does that, let alone a fairly mainstream x86_64 one? In a purely theoretical sense, what you say is plausible, but in the “real world” it’s simply not done.

It was done that way in the original 8086/88: https://www.reenigne.org/blog/8086-microcode-disassembled/

(its successor the 80186 already had a divider in hardware)

I guess I wasn’t explicit, I meant something made in the past decade or two. Going back to 3 decades ago, there’s a handful I can think of, going back almost a half century like the 8086/88, there were even more.
