Illustrator: Pathfinder divide not working as expected


I'm trying my hand at making a map using illustrator. I'm fairly new at it so I'm still learning the ropes. I'm trying to divide up a continent into several countries using border lines. Here's an example of what I'd like to do:

This image restriction for new users is kinda silly I would end up with two separate, enclosed figures sharing that border. I've tried using divide, but it doesn't work like all the tutorials (like this one) are saying it should. They say that when I use divide, it should keep both figures. But when I use the divide tool with the coastline and border, it cuts the left country as I want it, but discards the right, like shown below. Naturally, I want to keep both.

(I mean, I've got over 10 rep on other sub-sites)

Any help would be much appreciated. Thanks.

Accepted Answer

It would appear what you really want is Object > Path > Divide Objects Below

divide below.

If you have a shape, draw a path where you want to split the shape, select the path and choose Object > path > Divide Objects Below, you will then be left with two separate shapes split where your path was drawn.

The Pathfinder Divide function will not retain both portions of a shape. And the response in that question you linked to indicated the shape was duplicated before performing Patherfinder operations. The divide did not retain both sides of the shape.
