X + 1 + X + 1 + X +1+ X +1 = 2X -3+ 2X -3+ X -1+ X -1
4x + 4 = 4x-6+2x-2
4x+4=6x-8
12=2x
6=x
Side lengths:
6-1=5
6+1=7
2(6)-3=9

To get the greatest possible quotient, you need the biggest possible 
dividend and the smallest possible divisor.
       96,432 divided by 225  =   428.5666...  <== greatest possible
       23,469 divided by 522  =     44.9597...  <== smallest possible
