cumulative sum by Date and address

The code below will produce your desired results from the data you posted.

You'll need to replace the Source line with your actual data source.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("i45WMtQ31DcyMDJW0lEyBJKxOiAhI0whuCojYxOokDGmkCmmRjOYkImpGboQWFUsAA==", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [Date = _t, #"Address Number" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"Date", type date}, {"Address Number", Int64.Type}}),

//To be able to return to original order
    #"Added Index" = Table.AddIndexColumn(#"Changed Type", "Index", 0, 1, Int64.Type),
   
//Group by Address Number, then add an Index column to each subtable (starting with `1`)
    #"Grouped Rows" = Table.Group(#"Added Index", {"Address Number"}, {
        {"Count", each Table.AddIndexColumn(_,"Order Count", 1, 1, Int64.Type), 
            type table [Date=nullable date, Address Number=nullable number, Index=Int64.Type, Order Count=Int64.Type]}}),
   
    #"Expanded Count" = Table.ExpandTableColumn(#"Grouped Rows", "Count", {"Date", "Index", "Order Count"}),

//Return to original order
//Then remove the index column and set the columns to desired order
    #"Sorted Rows" = Table.Sort(#"Expanded Count",{{"Index", Order.Ascending}}),
    #"Removed Columns" = Table.RemoveColumns(#"Sorted Rows",{"Index"}),
    #"Reordered Columns" = Table.ReorderColumns(#"Removed Columns",{"Date", "Address Number", "Order Count"})
