a common method works as follows. first you split your string 
into chunks where newlines might appear. e.g. after every space. 
then you keep track of a "line buffer", you keep adding chunks to 
the line buffer until it's too wide, then you remove one chunk 
and output the buffer as a line. rinse and repeat.

I'll get to work on some example code.
