dreamweaver CC layout help please (using floats)

Hi All,

I'd appreciate any help with this problem creating my ideal Dreamweaver CC layout!

Please see the screen shot below. Everything is perfect except I can't get the div labeled "div-right" at the bottom to sit on the right just like the one that sits on the left of middle divs that I have already aligned nicely.

I have my coding the way I understand most, so I can attach that in another post if needed.

Thanks!!!!
