How to make line breaks without spaces?

Question

Bootstrap

There is a line

<div class="row">
     <div class="col-lg-4">
         fffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffffff
     </div>
</div>

Which in the layout is displayed at full length. Regardless of block size. Everything else is correct. But a line without spaces gets into other blocks, crosses buttons, etc.
How to force such line to be within the block?
