What does the non-zero remainder in a CRC detect?

Hi everyone, if I were to receive 101110010 on the receiver's side, and conduct division using 1001 as the generator value, I get a non-zero remainder. Just to clarify, would a non-zero remainder indicate that the data bits (101110) has an error or does it generally indicate that there is an error somewhere in 10110010, meaning there is an error in D and/or R. Thank you!
