There may be better solutions, but this should work:

str.scan(/(?:[^\/]+(?:\/|$)){3}/)

This returns an array of strings obtained by splitting str after every 
third /. The last entry of the array contains the rest of the string:

'a/b/cd/efg/h/i'.scan(/(?:[^\/]+(?:\/|$)){3}/)
=> ["a/b/cd/", "efg/h/i"]

I hope this helps
