Jquery .each through Divs inside another Div

I currently have the following html:

Apologies for edit, I was not paying attention when i wrote this.

 <div class ="left">
    <div>1</div>
    <div>2</div>
    <div>3</div>
</div>

I am using the JQuery .each command to iterate through each div using $('div').each. Although I only want to iterate through the divs inside the div with the class name 'left'.

I have tried using $('.left > div').each but it did not work.

Any help appreciated.
