A standard deck of 52 cards contains, inter alia, four Queens.
After a perfect shuffle, one turns cards from the top one after another, until the first Queen appears.

Please provide your justified estimate at what step will the 1st Queen appear.

When I calculate it in Excel, I get exactly 10.6, which looks a lot like (52+1)/(4 + 1)
