I think you are missing one step after using the view break controls. The view break will cut out a portion of the view but the pieces that remain are do not get moved closer to one another.
Once the view is broken there is a little arrow inside the crop region of the remaining parts. it is sometimes hard to see because drawing elements obscure it. You can use this arrow to move the portions of the view closer to gether so whn placed onto a sheet it will fit.
You can find more information on this process at the resizing crop regions page of the wikihelp. The part that specifically mentions this is near the bottom of this page.
