Q. Divide. Give the exact answer, written as a decimal.

\newline

8 \div 5=\square

Set up division problem: Set up the division problem. $\newline$ To divide $8$ by $5$ , we write it as $8 \div 5$ or as a fraction $\frac{8}{5}$ .
Perform the division: Perform the division. $\newline$ Since $8$ is not a multiple of $5$ , we expect a decimal result. We can start by seeing how many times $5$ goes into $8$ , which is $1$ time with a remainder of $3$ . To find the decimal, we can add a decimal point to the $8$ (making it $8.0$ ) and bring down a $0$ to continue the division.
Continue with remainder: Continue the division with the remainder. $\newline$ Now we divide $30$ (the remainder of $3$ with an additional $0$ after the decimal point) by $5$ . $5$ goes into $30$ exactly $6$ times with no remainder.
Write final answer: Write the final answer. $\newline$ Combining the whole number and decimal parts, we get $1.6$ as the exact decimal value of $8$ divided by $5$ .
