Screenshot to divide

I have made a screenshot of a web page and the dimensions came to roughly 17" x 35"  I've got it in photoshop to slice so that i can make it into 3 readable pages of 8.5" x 11", but i can't figure out how to do the "Save to Web" to where it saves each slice as its own separate file.  I'm using CS5.  Any help would be appreciated.

2 different world's my friend. when you take a screenshot of a webpage its like taking a photo
so cutting this photo into smaller photos will not make it a webpage again. A webpage is made of HTML code. So the only way to show this now is to include this slice (photo.jpg) in html code in a file.
Save for web only prepare the photo so that it is smaller in size and sutable for web.

let me rephrase

1 jpg file to be split into 3 jpg files of equal dimensions.

8.5 x 33

into 8.5 x 11 + 8.5 x 11 + 8.5 x 11

and each 8.5 x 11 saved as file1.jpg, file2.jpg, and file3.jpg

open the layer  (F7)
create 3 new layers (tool beside the trash can in the layer, bottom corner)
now using the "rectangular marquee tool" in your tool box (upper left corner)
make a squere around your first slice - press ctrl-C (copy)
click on the first new layer you created in your layer tool
press ctrl-v (paste) - click on the eye in the layer tool to turn off the other layers.
now click on the save for web
