How is the inheritance of a deceased father to be distributed among four wives, one daughter, two sons, and twelve brothers and sisters?

The wives receive one-eighth due to the existence of a lineal descendant, and this is distributed equally among them, based on the Almighty's saying: (But if you have a child, then for them [i.e., the wives] is one eighth of what you leave) An-Nisa/12. The remainder goes to the children, 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) An-Nisa/11. The brothers and sisters receive nothing, as they are excluded by the sons. The inheritance is divided into 40 parts: the wives receive 5 shares, distributed equally among them; the daughter receives 7 shares; and each son receives 14 shares.
