Count a column as percentage

hi guys, i need to count one column but i need the result as percentage.

the column that i need to count is [disponibilidade] and i need to count if it = “parcial”
so i did with virtual column and in app formula:


but i need to get the result as percentage from the total “358”

so if the count is 11 the result must be 3% (11*100/358)

is there anyway to do the calc with the Count appformula above?
because i need 3 percentages so if i do the calc separated i will need 6 virtual column instead 3.

You could change it to percent column and then use…
