Follow this Ray-Casting Tutorial For Game Development And Other Purposes by F. Permadi. It describes the easiest method. It was also described in the Tricks of the Game-Programming Gurus book by André LaMothe.

I've implemented it several times. Takes ~1K lines of code or less (depending on your programming language and how advanced you want your raycaster to be). Basic school math.
