It depends on your objective and your starting point. If you can clearly 
identify the area you want to be background, then remove it from the image. This 
might need you to use the lasso tool to outline the background, which might take 
some time - especially if it is in pieces.

If the background color is set to white (the default state) then exporting to 
jpg will produce your image with a white background.

If, however, you want the background to be the default background of your image 
(rather than simply "white"), you should add an alpha channel to the image, then 
remove the area that is supposed to be background (it will show up as a 
light-gray/dark-gray checkerboard), and export the picture to png.

If this doesn't help, perhaps you might rephrase your question. Some of the 
tutorials might also help.
