How is the estate of a woman who died, leaving behind a husband, two daughters, two sisters, two maternal aunts, a maternal uncle, and a grandmother, to be distributed?

If a woman dies and leaves behind a husband, two daughters, two sisters, two maternal aunts, a maternal uncle, and a grandmother, the inheritance is distributed as follows: The husband gets one-fourth (3 shares), the two daughters get two-thirds (8 shares), and the grandmother gets one-sixth (2 shares). The two maternal aunts and the maternal uncle get nothing because they are from among the relatives by blood (dhawu al-arham). The two sisters get nothing because nothing remains after the sharers of fixed portions due to 'awl (proportional reduction), as the estate is divided into thirteen equal parts.
