Finding the remainder in binary division.

I am trying to calculate a frame check sequence from the following binary strings:

String firstString ="110101"

String secondString ="101000110100000"

By doing:

long remainder = Long.parseLong(secondString) % Long.parseLong(firstString);

System.out.println(remainder +"remainder");

Which gives me the result as a long (surprise surprise :P ).

Is there a way to tell java to return the binary remainder 01110 ?

thanks for having a read again!!
