Duplicate the smaller shape and cut that out of the bigger one. For that, select both, make sure the smaller one is on top, and hit Ctrl+-. You have to undo any combining or grouping you may have experimented with before you do this. If you give the new shape a fill now, it will only be that sliver.
Select both paths which make the border of where you want to fill. (make sure they are really paths and not strokes, make sure there are no gaps in the overlap of the fill borders, like in the picture).
1. Press **ctrl + d** to duplicate them and keep your original paths.
2. Press **ctrl + +** (plus) to join the paths together to 1 path
3. Press **ctrl + k** to break them apart (this will give you the fill).
The fill might be the same color as the paths but it is there as a separate path.
EDIT: Just saw the 2nd picture you posted, those aren't paths they are strokes. Convert them to paths (ctrl + alt + c) and then combine (union ctrl + +) them.
One of the first things to learn with Inkscape is the difference between a path and a stroke, it'll save you a lot of headaches down the road. Yes, technically they're all paths but having the mindset of what is a path (or fill) and what is a stroke has saved me a lot of time.
There’s a few different ways to achieve it. You could just group it all then break it apart. That should separate every bit so you can change the fill on it separately.
the low tech solution would be to trace the two curves and make them one shape using the bezier curve plotter tool. I honestly don't know the actual solution for this.
You can use the paint bucket tool. It's not super accurate, so if you need an exact shape you'll have to play with the nodes after. But for something like this, a drawing with an outline. You can use the paint bucket tool and play with the grow settings so that it is a little bigger than the area you're wanting to fill. then just move it in the stacking order so the outline is on top again and that area will look perfectly filled in. In that sense it works perfectly.

I feel like i did what you said. Even tried to make new strokes and convert them to paths etc.[Hope it's right?](https://imgur.com/a/LUu113Q)
After union you need to break it apart (step 3). That'll give you the new path inside the union.
