pathfinder - How can I cut up a raster image in Illustrator?

I want to split this apple (jpeg) into pieces along the outline I've created over it. I created and edited a pie chart/graph for the lines, then edited it to conform to the apple shape. I want to be able to show one piece of the "pie" at a time as a separate image. I tried path > divide objects below and all of the pathfinder combinations I could. I used the graph tool to create the "pie" and edited it by hand to conform it to the apple shape.
