Large gap between baseboard and floor


We recently replaced our kitchen floors and now we have a large gap between the baseboard and floor on one side of the room (turns out our floor is a little uneven). I care a little about how it looks, but mostly I'm concerned about the very cold draft coming in through it (this is an external wall and right above the garage.)

This gap is a little too big to calk. Any tips on what to do here? Should I use a quarter round molding and put some insulation behind it? What kind of insulation? Any other tips?

Here are three images that show what this looks like: 1 2 3

Yes you need 1/4 rd.
The insulation really needed to be done under the floor and in the rim joist.
If it's an old house with balloon framing there should be fire blocking added to the bottom of the stud bays.
That gaps big enough that I would used round foam cording not caulking.
You'll find it in any home store in the masonry dept.

Once you get the draft eliminated, I'd install shoe mold. It will look better than caulking [or 1/4 round]
If you prime, sand and apply 1 coat of enamel prior to installation it will save you a bunch of time/work.
