What is the least verbose way of doing a nested for loop?

I'm trying to do repeat a code block, but have something happen every 5th time.

In English:

Do this 30 times, every 5th time take an additional step

My Ruby so far:

  6.times do
     5.times do
        #standard step
       end
     #perform additional step
   end

but I wondered if there was a clever way to do it?

mostly you do "every nth time" problems with a modulo like this:

30.times do |n|
  # standard step
  if n % 5 == 0
    puts n # extra step
  end
end
