Imagine a large number of chips on a table. If we make stacks of size 13, we get a certain number of stacks with 3 chips remaining.
If we have 6 times as many chips to begin with, we get 6 times as many stacks of 13, and then 6 piles of 3, or a total of 18 chips not included in the stacks. We can stack up 13 of those, and we have 5 chips left over. So the remainder is 5.
No algebra!
