keeping track of how many times a number shows up

Say, for example, I have a spreadsheet as follows:

0 1 1 2 3 2 0 1 2
1 2 1 2 3 3 1 0 1

Is there a way to count the number of times a specific number shows up and have excel post it to a different cell? I need to know how many times a certain number came up for a specific row, and how many times. Thanks
