8 $overline{)3.000}$

Explanation:

Step1: Divide 3 by 8

Since $3 < 8$, we write 0 as the whole number part, then add a decimal point.

Step2: Bring down first 0, make 30

Calculate $\frac{30}{8}=3$ with remainder $30-(8\times3)=6$. Write 3 after decimal.

Step3: Bring down second 0, make 60

Calculate $\frac{60}{8}=7$ with remainder $60-(8\times7)=4$. Write 7 after 3.

Step4: Bring down third 0, make 40

Calculate $\frac{40}{8}=5$ with remainder 0. Write 5 after 7.

Answer:

$0.375$
