with this code
digs 0 = []
digs x = x `mod` 1000 : digs (x `div` 1000)
for example: 24889375
we take the result [375,889,24]
how can i make this one ["375","889","024"]

The most idiomatic way to do this is to use the functions map
and show
.
Prelude> map show [375,889,24]
["375","889","024"]
show
can be used to convert most values to a string. map
applies that function to every element of a list map
.

Prelude> import Text.Printf
Prelude Text.Printf> map (printf "%03d" :: Int -> String) [375,889,24]
["375","889","024"]
