Breaking up a packed int value and splitting it up into two components c++

Without using any STL library function, can anyone kindly explain to me how to take a big int, lets say 288895 into something like 2888 and 95? I have trouble thinking of a proper solution.

For Example 288895 could be used to store both the employee number and the score employee got as his rating. I want it to be split into 2888 for student number and 95 for the exam.

Edit* I have thought of separating this into a string, using 

substr(1,4)

in order to recreate a new string for the first part and using substr() again to recreate the string for the second part. Then I would return the function using these strings, I wonder if that was a viable option to apart from using the % operator like the comments suggested...

Thank You.

I would look at using the mod (%) operator. 288895 % 100 gives 95, and you can integer divide by 100 so 288895 / 100 gives you the 2888.
