How do I buy a deposit on Binance?

Could you please elaborate on the process of purchasing a deposit on Binance? I'm a bit unclear on the steps involved and I'd like to ensure I'm doing it correctly. Specifically, I'm wondering if I need to first create an account on Binance, deposit funds into my account, and then navigate to a specific section to make the deposit purchase. Are there any fees associated with this process? Additionally, I'd like to know if there are any specific requirements or qualifications I need to meet before I can purchase a deposit. Any detailed information you could provide would be greatly appreciated.
