Sorry for the necroing here!. I've been using my method of doing "for each (char digit in List) { List.Add(digit - 48) }" to separate each number for several katas now, then I saw this solution and thought "Gotta do it that way now!!!" then saw adams85's comment and thought "goddarnit". I had already noted the code down, happy to being able to do better next time so that was such a shame. Then saw yours and hope came back to my soul, thank you, stranger.

Thanks for Math.DivRem.
