How is inheritance divided between the deceased's father, husband, and only daughter?

If the deceased woman left no heirs other than a husband, a father, and a daughter, then the husband receives one-fourth due to the presence of a lineal descendant heir. The daughter receives one-half. The father receives one-sixth as a fixed share (fard) due to the presence of a lineal descendant heir, and he takes the remainder by residuary right (ta'sib). The estate is divided into 12 shares: the husband receives 3 shares, the daughter receives 6 shares, and the father receives 2 shares as a fixed share and 1 share by residuary right, making his total share 3 shares.
