divide.
$13.8 \div 3 = \boxed{8}$ (with a red cross mark on 8)

Explanation:

Step1: Divide the integer part

Divide 13 (the integer part of 13.8) by 3. $13\div3 = 4$ with a remainder of 1.

Step2: Combine the decimal part

Bring down the 8 (from the decimal part of 13.8) to make 18. Now divide 18 by 3. $18\div3 = 6$.

Step3: Combine results

The quotient from the integer part division is 4 and from the decimal part is 0.6 (since 6 is in the tenths place). So, $4 + 0.6 = 4.6$.

Answer:

$4.6$
