Cyclic Redundancy Check - Message starting with 0
I'm wondering how to encode a message starting with 0. ie. Given code: 10111 message: 001011110 I've tried divide this multiple times but am not sure if I can ignore the first two zeros of the message as they correspond to x^7 and x^8... Any help is greatly appreciated.

If the crc is initialized to zero, then leading zeroes in the message to be encoded won't affect the crc. If the crc is initialized to some non-zero value, then it will get cycled each 0 bit encountered.
