Grabbing the pseudocode from wikipedia: 

function quicksort(array)
     var list less, greater
     if length(array) ≤ 1  
         return array  
     select and remove a pivot value pivot from array
     for each x in array
         if x ≤ pivot then append x to less
         else append x to greater
     return concatenate(quicksort(less), pivot, quicksort(greater))

iteration 1 
 Choose any pivot, for instance, 3 looks good then
(1,1,2,3)  3 (4,5,9,6,5,5)

iteration 2
Chosing 2 as pivot, and 5 as pivot
(1,1) (2) (3) 3  (4,5,5) 5 (6,9)

Third iteration, chosing random pivot as usual
(1) (1) 2 (3) 3 (4,5) 5 5 (6)(9)

Last iteration:
1 1 2 3 3 4 5 5 5 6 9 

I hope I am right and I hope it helps. :)

This should give you the concept. Yellow bg indicates May Not Require This Step/Possibly wrong. Red int indicates the selection of the partition point ( starting at right -- pivot). underlined is the position where it is sorted. { } =selection of block . When block has one element, it is sorted already. Bold int= upcoming pivot
