How to buy Beam on Binance?

Excuse me, I'm a bit confused about how to purchase Beam tokens on Binance. Could you possibly explain the process step by step? I'm not very familiar with crypto exchanges, so it would be great if you could include any necessary prerequisites or setup steps. Additionally, would it be possible to highlight any fees or costs associated with the purchase? I'd also appreciate any advice on how to ensure the security of my transactions and account. Thank you in advance for your assistance!
