Cereus Cactus Split In Two

Picked up this sectioned of Cereus cactus back in August, which brought me three blooms at that time. All this time
I had suspended on a broken clay pot outdoors for drying.
A month ago I noticed two new cactus sprouting. I've
wanting to split this in two for a month or so. So, yesterday
was that day and I'm going to keep indoors to dry and callus.
