How is the inheritance divided between a daughter, a wife, a maternal brother, and two maternal sisters?

The deceased's wife receives one-eighth as a prescribed share, and his daughter receives one-half as a prescribed share. The daughter takes the remainder by way of return (radd). The brother and the two sisters from the mother's side receive nothing, as they are excluded by the daughter. The inheritance is divided into eight shares: the wife receives one share, and the daughter receives four shares (the half). Three shares remain, which the daughter takes by way of return, making her total share seven shares.
