How is inheritance calculated for heirs including: 3 sons, 5 grandsons, 1 daughter, 1 granddaughter, and 1 wife?

If the deceased left behind only a wife, three sons, and a daughter, then the wife receives one-eighth (1/8) as her prescribed share due to the presence of inheriting descendants. The remaining portion is distributed among the sons and daughter by way of ta'sib (residuary inheritance), with the male receiving the share of two females. The son's daughter and the son's sons receive nothing, as they are blocked by the presence of the direct son. The estate is to be divided into eight shares: one share for the wife, two shares for each son, and one share for the daughter. Matters of inheritance must be referred to the Sharia courts for investigation.
