How is an estate of 15,500 Egyptian pounds to be divided among a wife and two daughters, considering that the two brothers and sister entitled to the remaining portion of the inheritance died after the demise of the deceased?

If a person dies leaving a wife, two daughters, and three siblings (two men and one woman), the inheritance is divided as follows:

The wife: She receives one-eighth due to the existence of inheriting offspring (the two daughters), as Allah Almighty says: (But if you have offspring, then for them [the wives] is one-eighth of what you leave) An-Nisa/12. The two daughters: They receive two-thirds, as Allah Almighty says: (But if there are [only] daughters, two or more, for them is two thirds of what he left) An-Nisa/11. The siblings (two men and one woman): They receive the remainder by way of ta'seeb (residual inheritance), with the male receiving the share of two females, as Allah Almighty says: (And if there are brothers and sisters, then for the male is the share of two females) An-Nisa/176.

Accordingly, the amount is divided into 24 shares: The wife receives 3 shares, the two daughters receive 16 shares (8 shares for each daughter), and the siblings receive 5 shares (two shares for each brother, and one share for the sister).
