FWIW this unholy thing works for me,
fifths :: String -> String
fifths = splitIntoN 5
splitIntoN :: Int -> String -> String
splitIntoN n string =
let stringToSplit = string ++ replicate (n-1) 'X'
in unwords (map fst (take n (tail (iterate (splitAt (div (length
stringToSplit) n) . snd) (undefined, stringToSplit)))))
Admittedly, a 'let' might be nice to name some intermediate
computations.
