If you look on the PICLIST at http://www.piclist.com there's floating point code, or MicroChip have an application note about it.
Presumably that isn't the only calculation you need to make?, if it was, simply do it on a calculator (or a piece of paper) and store the result. You could also scale the calculation, make it 233*34, which you could do with a simple 16*16 multiplication - then divide it by 1000 (by shifting the decimal point).
