My magician gives you 3 regular dice and asks you to do the following, while he is out of the room:
"Roll them, and write in sequence the three results, followed by a 3-digit number representing the hidden sides of the rolled dice.

Once you got the 6–digit number, divide it by 111.

THEN CALL ME."

Then he exits and you roll 1,2,4 and write down 124653, divide by 111 and get 1123. The magician upon entering the room gets the result and quips within a second 1,2,4.

How did he do it?

Since the first three digits will always add up to less than 10, it is no great surprise to the magician that they were so. If they added up to more than ten, then the audience member was not following instructions correctly.
