How to buy USDT ERC20 in Binance?

Could you please guide me through the process of purchasing USDT ERC20 on Binance? I'm new to the platform and a bit confused about the steps involved. Specifically, I'm wondering how to select the right trading pair, deposit funds into my account, and execute the trade. Also, are there any fees or limitations I should be aware of? It would be great if you could break down the entire process in simple, easy-to-understand steps. Thank you in advance for your help!
