Well, the only problem with going that route, is the one group is not
equally sized to the others. 18 is ok for a group in this instance, but if
it was a remainder of only 1 or 2, there would be an issue. Which is where
I come to looking for a the right method to break it equally.

_Dan:
As I see it -- you are asking is "What would be the 'optimum' group
size for 1,252,398?"
"Optimum" here meaning:
1. A group size of 30 or under;
2. All groups being of equal size.
Is that correct?
There may not be an exact solution, but a first order attempt would
be to divide the total number by 30 and check the remainder (i.e.,
MOD), the do the same for 29, 28, 27... and so on.
The group size "solution" would be a number with a zero remainder OR
with a remainder closest to your group size.
That would be my first blush solution.
Cheers,
