If you are riding a bike that can freewheel then advice to “not use the brakes” is nonsense. Unless you only trackstand on an upslope then you have to use your brakes. As had been said, in and of itself it isn’t that useful a skill, but it does help with slow speed balance and manouvers.
Use your brakes if you want to especially when learning what it feels like. By all means progress to using an upslope with no brakes but don’t feel bad if you do.
Head up and look to the distance.
Stand up with your cranks level.
Roll to a stop. (using your brakes if you want)
Turn your handlebars towards your forward foot.
As with all skills it takes time and practice.
Edit. Also remember that it is not passive, you will have to move your body around to maintain balance.
