Divding of estate

Assalaamu-alaikum respected Mufti-sap. This is a question on the shares of inheritance in a specific situation.
The deceased was a married woman with no children. She is survived by her husband, mother, father, paternal grandmother, a brother and a sister. Assuming the net amount left in her estate after paying all debts and bequests is 100, what is the proportion that each of the above survivors will get?
2nd question – How does the above change if the husband divorced her before her death but while the period of Iddat was still running?
