How do you do square root?


Sometimes, the answer is obvious, such as 3 being the square root of 9. However, I was never able to understand how the square root operation is any different from regular division, given less obvious numbers. Such as, how would you figure the square root of, say, 43,560. ?? (That happens to be the square footage of an acre, and I need the root to know how many linear feet down one side of an acre, for my model train layout.)
