I'm going to hazard a guess there's too many variables here......the 922968215732 (usercode) and 359751198262 (passcode) are the multiples of the Unicode values of the corresponding characters in the username & password, but without knowing how many characters there are in each, it's going to be guesswork to decrypt the username/password. Plus there's the manipulation of dividing the usercode by 10 if the total (m) is more than 1000000000000 before you reach the end of either the username or password, and then rounding it to the nearest integer.
