Selim, my application is this:

I'm doing a Junior Project for my school, Oregon Tech. Our project is to develop a digital tachometer for my car. It has two microcontrollers, one to count the sparks and determine RPM, and one to control the number and led displays.

I realize that a microcontroller is not the best choice for counting sparks, but it is an embedded systems course so we are stuck with it.

What I'm doing is using Timer 0 to see the time between sparks, and use that time length to determine RPM. Unfortunately, in order to do this conversion, I need to divide 15 million by the number of sparks to get RPM. That's where the 32 / 32 bit divide comes in.
