What if the size of the matter that is about to enter the black hole alot bigger than the hole of the black hole itself, would the matter entering the black hole be broken down or would the black hole expand in some sort of way or what?

The way a solid object stays together as one solid object is because of the forces between the atoms and molecules inside the object. If you push or pull one end of it, that pushes or pulls the bit next to it, which pushes or pulls the bit next to that, and so on and so on until the whole object appears to move together.

However, it actually takes some time for a push or pull on one side of an object to reach the other side. This is actually much slower than the speed of light - it's the speed of sound. This means there's no need for the entire object to get pulled in at once - one part could cross the event horizon before the other end even knows what's happening.

Also, this strength is of course not infinite - if the strength of the bonds in the solid object are weaker than the tidal forces of the black hole, the object will get ripped apart.

So the short answer is that it would break down whatever is falling into it.

The black hole would also expand a bit, just because it's gaining extra mass. But it's not like it's opening its mouth to suck in something bigger than its diameter.
