          y^2 + 9 
        ______________________________
y^2 - 9 | y^4 + 0y^3 + 0y^2 + 7y +  1
      -  (y^4 + 0y^3 - 9y^3)
       ---------------------
                       9y^2 
                    - (9y^2 + 0y - 81)
                    ------------------
                              7y - 82

{{{(y^4+7y+1)/(y^2-9)=(y^2+9)-(7y-82)/(y^2-9)}}}
