Let's take AES: The Advanced Encryption Standard uses xor on single bytes (some other algorithms use blocks of 16 or 32 bits; there's no problem with sizes other than 8 bits). The round key will be XORed with the intermediate result and after that permuted and substituted. XOR also gets used in the key shedule.
