Table Calculations without row limit

[akifozsoy]

Hello,

I have a sales table by seller. I want to calculate percent of sold quantity by each seller. But when i try these as in the screenshot, "Percent of Sold %" column calculated based on row limit. 

Is there any way to calculate percent of column without row limit? 
2.38% ==> 12,927 / 457433. 
But i want to calculate: 12,927 / 518,985

Thanks
