Binary values representing polynomials in GF(2) can readily be manipulated using the rules of modulo 2 arithmetic on 1-bit coefficients. This online tool serves as a polynomial calculator in GF(2). Be aware that this is not an ordinary binary calculator.
Enter binary values for two input operands and choose an operation. Select Polynomials to see the result in polynomial form. Select Discussion to see a detailed explanation of the underlying arithmetic.

Calculations in GF(2) are performed by MATLAB functions found within the Communications Toolbox.
>> a = gf( [1 1 0 0 1 0 1] );
>> b = gf( [1 1 0 1] );
>> [q,r] = deconv(a,b) % deconvolution is equivalent to division
q = GF(2) array.
