Oh, so if I use your method I won't benefit from compiler optimizations. 
Great.

Ok, have it your way:

   t:=gettickcount;
   x:=0;

   for I := 0 to 1000000000 do
   begin
      l:=i mod 1000000;
      x:=x+l div 7;
   end;

   writeln(x);
   writeln('Normal operator: ',gettickcount-t,' ms');

   t:=gettickcount;
   x:=0;

   for I := 0 to 1000000000 do
   begin
      l:=i mod 1000000;
      x:=x+SimulatedDiv7(l);
   end;

   writeln(x);
   writeln('Flying dickheads method: ',gettickcount-t,' ms');
   readln;



Normal method:	18984 ms
Flying dickheads method: 23063 ms

Closer, but your still slower dip****, and its even worse if you don't 
limit the range of the divisor.

Nobody cares.

**** off and die.
