Express 284 / 9 in decimal form.

Divide 14 by 9.

$$\frac{14}{9} = 1 \text{ with a remainder of } 5$$

So far, the quotient is 31.

Now we have 50. Divide 50 by 9.

$$\frac{50}{9} = 5 \text{ with a remainder of } 5$$

Divide 50 by 9.

$$\frac{50}{9} = 5 \text{ with a remainder of } 5$$

We can see a pattern here: the digit 5 will repeat indefinitely.

Therefore, $284 \div 9$ in decimal form is:

$$284 \div 9 = 31.555...$$

This can be written with a bar over the repeating digit.

$$284 \div 9 = \boxed{31.\overline{5}}$$
