How does division work?

The key reason being that you as a programmer really shouldn't have to worry about things like that as it is the compilers problem. Most compilers are written so that operations are optimized (for special cases like the one above).
Unless you are writing hardware drivers you don't need to worry about assembly level optimization. Even hardware shaders (which are run directly on graphics cards) are now written in a C-like language rather than in assembly like before.

Once again we disagree on this point. I think the programmer should always be aware of what is going on in his software especially in embedded systems space and clock cycles are vital, then again this paranoia could stem from my work on drivers in the Linux Kernel.
