what happens when trample creature hits prevent all dmage creature in magic

[Biefall]

The difference between the attacking creature's power and defending creature's toughness goes into the players life as damage.

[Ivlonkey]

no dmg is delt to the Defending creature there for trample dmg couldnt' go over the "toughness" of the creature..

[Kappu1]

You still have to assign enough damage to the defending creature to deal what would be leathal damage (even though it isn't going to be dealt to it) the remainder of the attacking creatures power is dealt to the player.

Trample only cares abot the blocking creature's toughness - it doesn't matter how much damage is actually dealt to the blocker. If a 5/5 trampler is blocked by Cho-Manno, Revolutionary, for example, you only need to assign 2 to Cho-Manno, and the remaining 3 can go to the defending player.
