Embedding div container from another site into an IPS post?

[Aramaech]

I'd really like to take a specific div container from another website and embed it into the html of a post in IPS.
I am aware this can't be done using html alone, or an iframe.  Unfortunately I'm not familiar with how to use jQuery or Ajax to do this.
I do have the ability to post html, thanks to Nathan Explosion. 

Specifically I'd get to take the Main Rankings container from this site and drop it into a post.
Does anyone know how to do this?

Any help would be greatly appreciated.  Thanks
