Need help : DAX Measure - Expected output vs Actual output

[Anonymous]

Hi Community, 

I need some help to resolve an issue i have been facing or trying to understand and fix it.  I have columns like MonthYear , Forecast 2021(% value) , Forecast 2021 Nr(numerator) , Total Count of rows ( Denominator) . Month year is a calculated column created using some format function from date .  Rest of the 3 are measures created . 

I have also added DAX codes for reference : 

Forecast 2021 Nr = CALCULATE(COUNT('Mainframe Turndown'[PROCESSNAME]),FILTER('Mainframe Turndown','Mainframe Turndown'[Turndown PeriodForecast]="5/1/2021"))

Total Count of rows = CALCULATE(COUNT('Mainframe Turndown'[PROCESSNAME]),FILTER('Mainframe Turndown',NOT(ISBLANK('Mainframe Turndown'[PROCESSNAME]))))

Forecast 2021 = [Forecast 2021 Nr]/[Total Count of rows]

Actual Output : 

My expectation is for May 2021 , Numerator value should be 391 and should be divided by 28852(total count of rows) . However, Numerator and Denominator are same (391) and when are divided , its showing 100% . I am expecting it to be 

-  391/28852  = 1.36% 

I am not sure how to change the Denominator part to work as i am expecting.  Below shown is the expected ouput . 

Expected output : 

Please Assist !!

@Anonymous I suggest to create a Datedim

use this function

 1 .CALCULATE(
       COUNT('Mainframe Turndown'[PROCESSNAME]),
       FILTER(ALLSELECTED(DateDim), DateDim[Date]="Desired Date")

2. Calculate(COUNT('Mainframe Turndown'[PROCESSNAME]),
    All(FACT Table))

3. DIVIDE(First Measure, Second Measure,0)
Please do let me know if it works!
