These commands helped us split a large file into two smaller components.

To create a split screen:
:split filename (the second screen will fill with either a new file or existing file, depending on whether or not the filename exists or not)

To find out what line you are on:
Ctrl-g

To perform a multi-line cut to that line:
:1 (gets you to the beginning of the cut-worthy text
Ndd (N=number of lines you wish to cut)

To switch between the windows:
Ctrl-ww

To past the multi-line cut:
p
