Here a solution with probe to debug

rules: [
     thru 

     (div-count: 1)
      some [
        "" mark:  ( probe -- div-count   if div-count = 0 [insert mark "closing main div"]) skip 
      |  skip
     ]
  ]
parse/all content rules 

The problems with your rules are, that the div-count is never or seldom subtracted. The parse pointer goes straight to the next opening div as to is always the first fulfilled condition.

You can break out or better return from parse if you add a to end after a successful condition. If you are unsure use brackets for grouping [ sucessful sub-rules ... to end ]

An example with an end-rule

end-rule: [] ; or none
rules: [
    thru 

    (div-count: 1)
    some [
        [""mark:  (-- div-count   if div-count = 0 [insert mark "closing main div"  end-rule: [to end]]) end-rule ]
    |  skip
]
