How to calculate big exponents (with modular division involved)?

I found the following equation online when working with cryptography.

1702^2732 x 2083^2526 = 704 mod 3119

Now I'd like to understand the math behind:

how do we calculate exponentiation with number that high?
how did we get this mod part?

From the article, it looks like the calculation has been done by hand, with no computer involved.
