# Long Division

### Adventures in Place Value and Front-End Estimation

### 7237 divided by 6.

Eyebrows raised, colleagues and students look on as I reach for a piece of scrap paper instead of a calculator.

*Divide.*

*Multiply.*

*Subtract.*

*Bring the next digit down.*

Of course, **their** calculator has already given them *"the answer"*. But they don't see the numbers like I do.

They don't see the dividend, . . .
