How can I free up some space?

AC Question

I have tablet from prestigio and it's a multipad quantum 9.7. And it works fine until I have to update or install an app. In settings it says it still has 112MB (under DATA STORAGE) and 4.81GB (under INTERNAL STORAGE). I am really confused why this thing says it has no more space when update is only 45MB big. And why do I have two storage sections, data and internal storage and why not have one single?

The filesize of an app that's listed in Google Play Store is just the size of the installer file. Apps often take up more storage once they're installed, just like on Windows PCs. And the system has a threshold storage level where it starts preventing you from installing more, because it has to keep enough storage free for other processes, like storing cached data.
