How to transfer money from your blockchain wallet to your bank account?

I'm curious about the process of transferring funds from a blockchain wallet to a traditional bank account. Could you please explain the steps involved in a clear and concise manner? Also, are there any fees associated with this process, and if so, how are they calculated? Additionally, how long does it typically take for the funds to arrive in the bank account after initiating the transfer? It would be great if you could provide some insight into these aspects.
