gf(2) mod

c = a % b

Calculate c = a/b, result is cremainder

gf(2) Polynomial long division

c = a/b

a = b00000000000000000000000000000100
a = 0x00000004
a = x2

b = b00000000000000000000000011000001
b = 0x000000c1
b = x7 + x6 + 1

  100 | 11000001

cquotient = b00000000000000000000000000000000
cquotient = 0x00000000
cquotient = 0

cremainder = b00000000000000000000000000000100
cremainder = 0x00000004
