Hi Luc,

You need to add it to the Fixnum class, and use self to get at the 
value, like so:

---===<<< SNIP >>>===---

class Fixnum
   def divisions
     n = self
     i=1
     while i <= n
       if n%i>0
         i += 1
       else
         yield n/i
         i += 1
       end
     end
   end
end

12.divisions {|x| puts x}

---===<<< SNIP >>>===---

I haven't checked your algorithm, just made the changes needed to get it 
to work the way you want.

HTH

PS. Don't forget to indent. ;)
