Trying to divide a large amount of polygons with a single line shapefile

I am a Student with a relatively intermediate skill set when it comes to GIS.

I was wondering if there is any good way to split or divide a large number of (~4000) polygons at the same time using a single line shapefile.

Essentially I have a boundary and a number of polygons that cross that boundary. In order to create a weighted average of different attributes within these polygons I would like to "divide" them into two parts. What I really need to do is calculate the area of side A and side B of each polygon AB, so if there is a way to do this besides "dividing" the polygons maybe that would work as well. I have tried a number of different geoprocessing tools so far but have been unsuccessful in having all or a large group of polygons "divide" at the same time. Please see below for visual.


Any help of suggestions would be greatly appreciated, however I have very little knowledge of how to use Python.

Thanks again,
