How is inheritance divided among 7 sons, 10 daughters, and 2 wives?

The deceased's estate is to be divided among his heirs as follows: The two wives receive one-eighth as a prescribed share, to be divided equally between them, based on the Almighty's saying: "But if you have a child, then for them [the wives] is one-eighth of what you leave." What remains after the wives' prescribed share is for the children by way of 'asabah (agnatic kinship), with the male receiving the share of two females, based on the Almighty's saying: "Allah instructs you concerning your children: for the male, what is equal to the share of two females."
