Primecoin Question

[busoni]

Here is genuine noob question, but I haven't been able to find the answer on my own.

In Sunny's paper, it says that the origin prime for a given block must be divisible by the previous block's hash.

But block hashes have letters in them. How do you get a number you can actually divide?
