Yes. It can also mean 'change' when talking about money returned to you when you pay for something (e.g. in a shop).
The occasions when the word "to see" uses Continous aspect are rather rare, that shouldn't work here.

The sounds seem okay, although there is something weird in the pronunciation at this point that you mention. Anyway, it's supposed to be sz.
"remainder" not accepted in this sentence, although it is allowed in other similar sentences....
