How do I transfer money from crypto to my bank account?

Could you please elaborate on the steps involved in transferring money from my cryptocurrency wallet to my bank account? I'm quite new to this and would appreciate it if you could break it down for me in a simple, step-by-step manner. Also, are there any fees associated with this process? And how long does it typically take for the funds to reflect in my bank account? Additionally, are there any security measures I should be aware of while performing this transaction? Thank you for your assistance.
