Remove leading digit from an uint in without parsing to string and back

I'm having a uint as 3123456, and I want to get 123456 as number (ideally uint), i.e. with the first digit stripped.I know I could parse it as a string, remove the leading character, and convert it back:

func (id *MyID) Scan(v any) (err error) {    asBytes, ok := v.([]byte)    ...    myDBNumber := binary.LittleEndian.Uint64(asBytes) // the field is of type BINARY in the db    myDBNumberStr := strconv.Itoa(int(myDBNumber))    myDBNumberWithoutPrefix, err := strconv.Atoi(myDBNumberStr[1:])    ...}

Since I'm using this logic in an sql.Scanner to parse IDs, I'm wondering whether there's a way where this parsing back and forward can be avoided, to improve the performance (or at least to compare the performance).
