I'm trying to create a digital thermometer which shows the current
temperature on a LCD. I was thinking of using the LM335 as the temperature
probe, as it is a linear temperate/voltage relationship. I was planning on
using  the PIC16F877 because of the 10 Bit ADC and the vast number of IO
pins.

Check out the 16C925 or 926.  These can drive an LCD glass directly.  They
are very handy for simple measure-and-display applications.

I've been looking around and i can't find how PIC's would represent
fractions, and how to substitute into formulas like the above.

Use either fixed point or floating point.
