How can I transfer my coin to my bank account?

Excuse me, I'm a bit new to this whole cryptocurrency thing and I was wondering if you could help me out. I've got some coins that I'd like to transfer into my bank account, but I'm not sure how to go about it. Could you give me a step-by-step breakdown of the process? I'd really appreciate it if you could take the time to explain it to me. Thanks in advance!
