Calculate the number of nonleaf pages:
(2016 / Size of nonleaf row) - 2 = Number of nonleaf index rows per page
(Number of leaf pages / Number of nonleaf index rows per page) = Number of index pages at Level 1
If the result is greater than 1, repeat the following division step, using the quotient as the next dividend, until the quotient is equal to 1. When the quotient is equal to 1, you have reached the root level of the index.
(Number of index pages at last level / Number of nonleaf index rows per page) = Number of index pages at next level
