 Using this property of ObjectId and also taking into consideration the fact that _id is always indexed, we can devise following approach for pagination:

 Fetch a page of documents from database
 Get the document id of the last document of the page
 Retrieve documents greater than that id
 In Mongo Shell your pagination code looks something like this

    // Page 1
    db.students.find().limit(10)

    // Page 2
    last_id = ...  # logic to get last_id
    db.students.find({'_id': {'$gt': last_id}}).limit(10)

    // Page 3
    last_id = ... # logic to get last_id
    db.students.find({'_id': {'$gt': last_id}}).limit(10)
