This solves it if you don't mind change of code. jsfiddle

    var $findme = $('#numbers');
var exec = false;
function Scrolled() {
  $findme.each(function() {
    var $section = $(this),
      findmeOffset = $section.offset(),
      findmeTop = findmeOffset.top,
      findmeBottom = $section.height() + findmeTop,
      scrollTop = $(document).scrollTop(),
      visibleBottom = window.innerHeight,
      prevVisible = $section.prop('_visible');

    if ((findmeTop > scrollTop + visibleBottom) ||
      findmeBottom < scrollTop) {
      visible = false;
    } else visible = true;

    if (!prevVisible && visible) {
    	if(!exec){
              $('.fig-number').each(function() {
          $(this).prop('Counter', 0).animate({
            Counter: $(this).text()
          }, {
            duration: 1000,

            step: function(now) {
              $(this).text(Math.ceil(now));
              exec = true;
            }
          });
        });
      }
    }
    $section.prop('_visible', visible);
  });

}

function Setup() {
  var $top = $('#top'),
    $bottom = $('#bottom');

  $top.height(500);
  $bottom.height(500);

  $(window).scroll(function() {
    Scrolled();
  });
}
$(document).ready(function() {
  Setup();
});

html,
body {
  height: 100%;
}

#upper-push {
  height: 100%;
  width: 100%;
  display: block;
  background: red;
  color: white;
}

  Scroll down
