The #insert code, I think, did what your pseudo-code would have done.
But, given the above, I'm a bit confused as to what you are trying to do.

Perhaps an example would be clearer.  For instance, given:

@array = [ 0,1,2,3,4,5 ]
counter = 3

What do you want @array to look like after your operation?
