Open hive, pull end frame out that has bees on, least likely to have queen on, check frame to make sure the queen is not on, brush/flick/pick off into honey jar.
Seal jar up
Make sure queen is not in jar, if she is, return to colony.
Do all this on a day that is least windy/wet and suited up. I would wear marigolds.
If getting on a day when bees are flying, around mid day, seal entrance and harvest flying bees that come back and can't get in.
