How do I fix the fucking bucket tool in Photoshop?

It gives me these blank spaces and I have to manually fill these which is a pain in the ass.
Also another question, but how do you color your drawings without going outside of the lines?
Picrel, I always have to erase the parts that are outside the drawing and that shit consumes time and is frustrating to deal with that.
