Here's a fiddle: http://jsfiddle/d9584/1/ , don't forget that your div actually needs a height in order to be scroll-able.

Then you just bind the scroll event and get the position with $(this).scrollTop()

@crisbeto has got it ( jquery) $("#element").scrollTop() or natively document.getElementById("element").scrollTop

Throwing in an example of something I use for odd scroll elements here and there - has some extra ui nice to haves so thought worth posting up too

http://jsfiddle/5Jz8A/

In the Markup add a class of .content-scroller any elements you want to scroll.

$(".content-scoller").on("scroll",function() {    
    _contentDiv = $(this);    
    _contentDiv.addClass("scrolling"); 

    /* is it top ? */
    if(_contentDiv.scrollTop() ===0) { _contentDiv.removeClass("nottop"); }
    else { _contentDiv.addClass("nottop"); }

    /* have we stopped scrolling ? */
    clearTimeout($.data(this, 'this_timer'));   
       $.data(this, 'this_timer', setTimeout(function() {
        _contentDiv.removeClass("scrolling"); }, 100)); 
});

*^ check 'has scrolling stopped' neat shorthand from **@yckart's answer****
