Finding my ether on etherscan

I copied my ether address off Binance and searched it on etherscan. It told me that the wallet could not be found. So my friend tried it and etherscan told him that he holds .3 ether in that wallet. The odd thing is, he doesn’t hold any of his ether on Binance. Does anyone have a solution or suggest of how I could find my Binance sub wallet on ether scan?
