How is the value of a car inherited from the deceased distributed among his heirs, and the heirs of his father who died after him, and the heirs of the deceased's mother?

If a father passes away and leaves behind a wife, a father, a mother, three sons, and seven daughters, then the wife receives one-eighth (1/8), the father and mother each receive one-sixth (1/6), and the remainder is for the children, with the male receiving the share of two females. If the grandfather then passes away, his inheritance is divided among his heirs: his wife receives one-eighth (1/8), and the remainder is for his children, with the male receiving the share of two females.
