How is the estate of a person who died leaving a surviving daughter from his first (deceased) wife, six daughters from his second (deceased) wife, and two grandsons (males) and a daughter-in-law from his deceased son (from his second wife) divided, knowing that he adopted another son?

If a person dies leaving seven daughters and two grandsons (sons of his son), the inheritance is divided as follows: The daughters receive two-thirds of the inheritance, based on the Almighty's saying: "But if there are [only] daughters, two or more, for them is two thirds of what he left." (An-Nisa/11). The remainder goes to the deceased's two grandsons, to be divided equally between them, based on the Prophet's (peace and blessings be upon him) saying: "Give the prescribed shares to those who are entitled to them, and whatever remains is for the closest male heir." The inheritance is divided into 42 shares; each daughter receives four shares, and each grandson receives seven shares.
