If it is just one instance that needs to be wrapped over 2 or 3 lines I would just use a few <wbr>
in the string. It will treat those just like <br>
but it wont insert the line break if it isn't necessary.
<div id="w74" class="dpinfo">
adsfadsadsads<wbr>fadsadsadsfadsadsa<wbr>dsfadsadsadsfadsadsads<wbr>fadsadsadsfadsadsadsfa<wbr>dsadsadsfadsadsadsfadsad<wbr>sadsfadsadsads<wbr>fadsadsadsfadsads adsfadsads
</div>
Here is a fiddle.
