delete-operator

I was reading this question Deleting a const pointer and wanted to know more about delete behavior. Now, as per my understanding:

delete expression works in two steps:

invoke destructor
then releases the memory (often with a call to free()) by calling operator delete.

operator delete accepts a void*. As part of a test program I overloaded operator delete and found that operator delete doesn't accept const pointer.

Since operator delete does not accept const pointer and delete internally calls operator delete, how does Deleting a const pointer work ?

Does delete uses const_cast internally?
