How else? ;-)
Thanks,

is there any way to assign a type signature to the helper function?
Same way you do for a top level binding:
dec2bin :: Integer -> [Integer]
dec2bin n = dec2bin' n []
where dec2bin' :: Integer -> [Integer] -> [Integer]
dec2bin' n acc
| n == 0 = acc
| otherwise = let r = rem n 2
m = div (n - r) 2
in dec2bin' m (r : acc)
