Here's a simple jQuery solution:

Not sure what you mean by "id like to span each divs nr."

Within PHP, you could use the DOM extension to do this, I would think.

Ahh if i can solve it with jQuery thats great! What I ment by "id like to span each divs nr." is that 'XX' should represent the actual number of the div. So the first div would have '01' instead of XX, the second '02'…

Tested jquery on jsfiddle -> http://jsfiddle.net/ZuDJD/ :

<script type="text/javascript" src="http://code.jquery.com/jquery-latest.min.js"></script>
<script type="text/javascript">
function zeroPad(num, places) {
  var zero = places - num.toString().length + 1;
  return Array(+(zero > 0 && zero)).join("0") + num;
}
$(function() {
  $('.count').each(function (i, div) {
     $(div).children('.count_nr').html(zeroPad(i+1, 2));
  });
});  
</script>
