I would like to know how does the V86 mode work (how to program and handle it,
exceptions in V86 mode, interrupt handling, etc.).

In other words, _everything_.
That's a little bit too in depth for here, I'm afraid. The message'd be many pages long. Try checking out the source of some of the OSs on this page which implement vm86 mode (a lot do so for access to bios ints).
Also of interest is Tim Robinson's VM86 Article:
