1..3.times is being parsed as:  1..(3.times).  Since times returns its
receiver, that's the same as: 1..3

Try this:

   cgi.div {
     (1..3).map {
       cgi.div {
         "hello from div"     # or "huhu", or whatever
       }
     }
   }

You could also do:

   cgi.div { cgi.div { "hello from div" } * 3 }
