What is the depth of recursion if we split an array into $\log_2(n)$ with each recursive call?

Question

We have a function which takes an array as input. It breaks an array into $\log_2(n)$ parts with equal sizes where $n$ is the size of the subarray. It keeps breaking each of the subarrays until there are only two elements left in it. What is the depth of this recursion?

Example of the process:

First we have $n$ elements and break them up into $\log_2(n)$ parts with equal sizes. Each of these parts has $\frac {n} {log_2(n)}$ elements in it. In the next level of recursion we will break each of the subarrays into $log_2(\frac {n} {log_2(n)})$ parts again with equal sizes. These will now have $\frac {\frac {n} {log_2(n)}} {log_2(\frac {n} {log_2(n)})}$ elements in each one of them. And we keep on breaking the array in this manner until we reach a subarray with only two elements in it.
