How is the inheritance divided among: two sons, one grandson (son of a son), and seven daughters?

If those mentioned have no other heirs, the inheritance is to be divided among the direct children by ta'sib (residuary heirship), 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." The wealth is to be divided into eleven shares; the male takes two shares and the female takes one share. The grandson (son of the son) does not inherit because he is excluded by the direct children. It is recommended to give him something from the inheritance if there was no will for him, based on the Almighty's saying: "And when [other] relatives and orphans and the needy are present at the time of division, then provide for them [something] out of it and speak to them words of appropriate kindness."
