bitwise operations in obj C

hello all,
I have a modulus operation in my code and it runs fine, but my original
algorithm avoided division all together for speed reasons - I am using
modulus due to a change in requirements.

How exactly (or can I) use bit operations to achieve the same effect and
increase my speed here ?

Code:

line_Number++;

if(line_Number % increment == 0)
                                           // lineNumber is any integer
value > 0, can get large w/ time - 100,000++
{                                          // increment is user selectable
integer from a set of given values
....
....
}

thanks.
