Then this begs the question of what avenue of consecration someone like Mary Magdalene would enter, who was neither widowed nor physically a virgin.
Some religious orders accept divorce/annulled women, and some don't. The director of novices or admissions would be in the best position to discuss the prospects of assuming vows following divorce.
The complicating factor which would give most orders pause, would be children. If a woman has children in the home, or has ongoing obligations concerning child support, that would probably prevent her taking vows in most congregations of women religious.
Other than religious orders, a woman might want to think of becoming an Oblate, a Lay Associate, or a member of a Third Order. I think there would be greater diversity in terms of the requirements of the various group: they are not all alike.
