Return number of days invoiced irrespective of the slicer

[EV]

Hello All, I have been breaking my head to find a solution. I need to return Avg Daily Sales with calculation of SalestotalMTD/Days Invoiced. I have a slicer for Division,based on the selection, days invoiced value changes accordingly. My problem is that I need to return Avg Daily Sales Total with this calculation, SalestotalMTD/(Value of Days Invoiced for 'C' division), FILTER is not working because of slicer
Days Invoiced should consider 'C' Division only irrespective of slicer selection

Days Invoiced	Division	Avg Daily Sales	Days Invoiced Total	Avg Daily Sales Total	SalesTotal MTD
8	A	$45,739.51	6	$60,986.02	$365,916.10
6	B	$148,800.43	6	$148,800.43	$892,802.59
6	C	$179,075.28	6	$179,075.28	$1,074,451.69

Can someone help please?

This worked, however when slicer is selected it shows value only for C division and not for the A and B, it returns blank for A and B.  

I updated Days Invoiced with the below, key was ALLSELECTED(Fact_Union),

CALCULATE (

DISTINCTCOUNT('Fact_Union'[Date]),

FILTER (

ALLSELECTED(Fact_Union),

AND(OR('Fact_Union'[SalesTotal] >0, 'Fact_Union'[SalesTotal] <0 ),Fact_Union[Division]="C")

)

)
