\\( 3 \overline{)2.58} \\)
\\( 3 \overline{)2.58} = \square
\text{(type a whole number or a decimal.)}

Explanation:

Step1: Set up division

We divide 2.58 by 3. First, consider the decimal 2.58. We can think of it as 258 hundredths.

Step2: Divide by 3

Divide 258 by 3: \(258\div3 = 86\). Since we had two decimal places in 2.58, the result is \(0.86\) (because \(86\) hundredths is \(0.86\)). Alternatively, using long division:

• 3 goes into 2 zero times, so we look at 25. 3 goes into 25 eight times (\(3\times8 = 24\)), subtract 24 from 25 to get 1.
• Bring down the 8 to make 18. 3 goes into 18 six times (\(3\times6 = 18\)), subtract 18 from 18 to get 0.
• The decimal point is placed above, so the result is \(0.86\).

Answer:

\(0.86\)
