need total of a column and then divide it to each row of that column

[Anonymous]

i need to divide 9/17 and get that value in a new column same for 5/17 similarly if i select any particular date from the slicer then the total will change same i need when the total changes like after selection say total is 19 then i need 19 in denominator and what ever number comes in the place of 9 that to replace 9 and get divide by 19 as 19 is the new total so basically need a new column in whh this be done and that column needs to be shown right side of count minutes field

@Anonymous , You need a measure like 

divide( Count(Table[Minute]), calculate(Count(Table[Minute]), allselected() ) )
