try (untested)

var divs = document.getElementsByTagName('div');
var number= undefined;
// loop over all divs
for(var i=divs.length;i-->0;) {
  // className colud have mor in than just "gwt-Label", so use a regular 
expression
  if( divs[i].className.match(/\bgwt-Label\b/) ) {
    // got the number
    number= divs[i].textContent;
    // so we're done…
    break;
  }
}
if( number !== undefined ){
  // youhave it
} else{
  // Lots of divs but not the one we searched.
}
 
I, btw, prefer nowadays to @require jQuery which makes stuff like this more 
easy.
