How much is $40,000 a year per hour?

I'm curious, how would one calculate the hourly rate if someone earns $40,000 a year? It seems like a straightforward question, but I'm interested in understanding the methodology behind it. Assuming a standard 40-hour workweek and 52 weeks in a year, how does one arrive at the hourly wage? I'm looking for a clear and concise explanation, possibly with a step-by-step breakdown.
