It has been a while, but I'll try. First make sure the hammer is cocked, then drift out the pins that hold the trigger group and remove it from the bottom of the receiver. Then push the bolt back a little and pull out (hard) on the operating handle and remove it. This should let the bolt, locking block, bolt carrier and the recoil spring struts come out to the front. Unless necessary for cleaning (if the gun was dropped in water or something like that) don't remove the butt stock or the recoil spring. Try to keep the shell latch in place until you can see how it fits.
I don't recommend taking down the trigger group. Leave the hammer cocked. If the group needs cleaning, dunk it in a cleaner (there are a number of good ones) and slosh it around. If you must disregard this advice, work in an area where pieces won't get lost, as they have a habit of flying away.
BTW, since you have the barrel off, check the position of the friction rings. Unless you know how you want them, reassemble the same way. That gun is an updated version of the old Model 11 (Browning Auto 5) and the friction rings are critical to proper operation.
