You don't need to take it to 16 digits :

mysql 4 :

select 1/666;

| 1/666 |
+-------+
|  0.00 |
+-------+

mysql 5.0.18:
select 1/666;
+--------+
| 1/666  |
+--------+
| 0.0015 |
+--------+

That has nothing to do with the precision of the calculation. It is due to the assumptions MySQL makes about how many digits to display. Try select 1.00/666 and it will give the 0.0015. Add more zeros, and it displays more significant digits.
