SQL Update Statement

SQL question. I have the pieces and I think the answer is in front of me
but can't figure this one out.

I know I can't do an update on a join but I was wondering if one could
be used in a subselect somehow to accomplish this. 

I have 2 temp tables...
 
Tbluserpt
        oboprce
        ifoth
        obdiv
        obcls
        
Tblusrp
        obdiv
        obcls
        okmark

How do I write a statement to...

Where tbluserpt.oboprce = 0

I want to update it to tbluserpt.ifoth/(1-(tblusrp.okmark))  

For the update I need to select tblusrp.okmark

Where

tbluserpt.obdiv = tblusrp.obdiv

And 

tbluserpt.obcls = tblusrp.obcls


Hope the question is clear.

Thanks,

Tim
