The post that is left behind is below ground level and surrounded by
a brick wall on one side and the other side is a driveway. Does
anyone have any bright ideas of how to remove the post? I have tried
drilling out the remainder with an auger bit but its not very easy!

I have done this a few times when I wanted to reuse a concrete
footing. What I found worked best was to get a 3" saw tooth bit
(e.g. 06J01.48 from leevalley.com) and drill out the core of the post.
The 3" bit allows you to stay within the post if you start slightly
off center or end up slightly off plumb; you don't want to hit the
concrete as that will quickly dull the bit. Getting the bit started
is the most difficult part, since the broken end of the post is
probably not flat.

Once you've drilled out the core of the post, use a long pry bar with
a flat chisel end to split the remainder of the post at the 4 places
it is thinnest. Then you can remove each of the remaining quarters by
prying it into the 3" hole and then pulling it out.
