How do I withdraw crypto from crypto to bank account?

Could you please explain to me, in simple terms, the process of withdrawing cryptocurrency from a crypto exchange to a bank account? I'm particularly interested in knowing the steps involved, any potential fees that may apply, and any precautions I should take to ensure a smooth and secure transaction. Additionally, is there a limit to the amount of cryptocurrency I can withdraw at any given time, and how long does the process typically take? Thank you for your help.
