Baseboard issue on slanted floor

Came across a situation where the floor on one of the walls dips down about 3/8" from left to right. It's about 6' long and it ends at the door to the room. The left side has a 45* miter to join with an existing BB and the right side will be a 90* butt to join the door casing. The dip, if I let the bb follow the floor, pulls the top of the 45* miter up. Leveling the baseboard leaves a rather large gap between the bb and the floor but tightens up the miter. Is there a fix/trick/experiential knowledge to address this? PS: the corner is square.

I need to know cuts for both ends of the bb knowing that left end is 45*. I do have a compound miter saw. I also have a case of caulking somewhere if that makes it easier
! I should mention that this is rather substantial base at 3/4 x 5 1/4", mdf.

Ultimately, I'm trying to get rid of/diminish the gap at the floor, if possible. There seems to be a trade-off between removing the gap and having the corner miter sit properly: when I level the bb, the miter fits nicely but there is a gap at the floor but when I let the bb follow the floor, the gap disappears but the miter opens up and that top of the bb sits up taller than the other bb it is meant to join. aaaarrrrgggghhhh!! Thanks.

Glue and pin more wood onto the bottom of the baseboard then scribe it to the floor.
