Predict the result
Thirteen thousand six hundred bags are shared equally among five markets.
Estimate how many bags each market receives before calculating.

Set up the model
Put the total first: thirteen thousand six hundred divided by five.
Count how many groups of five use the total. Each market gets the same share.

Work the example
Remove batches of groups of five.
One thousand groups of five use five thousand bags, leaving eight thousand six hundred.
Another thousand groups leave three thousand six hundred.
Seven hundred more groups leave one hundred.
Twenty more groups use the final hundred, leaving zero.
Add the group counts: one thousand plus one thousand plus seven hundred plus twenty.
That equals two thousand seven hundred twenty.

Check the result
Now try two hundred fifty two divided by seven.
Pause to calculate the quotient and remainder before checking.
[Eight-second silent pause to work; the answer remains hidden.]
Seven goes into twenty five three times. Seven times three is twenty one, leaving four.
Bring down the two to make forty two. Seven times six is forty two, so nothing remains.
The quotient is thirty six, with a remainder of zero. Seven times thirty six recovers two hundred fifty two.

Interpret the result
Each market receives two thousand seven hundred twenty bags.
Multiply that share by five to recover thirteen thousand six hundred.
There are no bags left over. Multiplication checks both the division and its interpretation.
