Sorry I am not so smart at Bitcoins and I did not get logic.
Someone has my wallet number. They sent to taht wallet 500USD. Blockchani devided this transaction into two parts. One arrived another in no idea where
Blockchain shows that I received one part of 45USD and I should be happy
?
My main questions would be the second part of payment should arrive shortly or it also a big question
?
No problem, you're just learning... But no, there's still something wrong with your logic.
Blockchain.info = just a company that analyses bitcoin's blockchain. When they mess up, it has no implication for you. They're not the ones sending BTC, they're not the ones dividing transactions, they're just a way of visualising the bitcoin network (the blockchain). The network itself will exist and work properly without blockchain.info.
I'm only guessing here, but because you said you were going to receive $500, i'm guessing address 1AWgAHXjX7fVWhsYZegMNCG3MBwzDXNMQZ belongs to your wallet. The wallet containing this address received an input of 0.18114157
BTC ($461 at the time of writing).
This unspent output can be used as an input by your wallet, hence you are payed.
The fact that you expected $500, but only received $461 is something you have to take up with the sender.
If address 1AWgAHXjX7fVWhsYZegMNCG3MBwzDXNMQZ does not belong to your wallet, you might be looking at the wrong transaction, or the sender might have decided to pay you in little tranches. Once again, you'll have to contact the sender to clear this out.
