Here are the calculations for the circled problems:

Part 1.1

To divide by 10, move the decimal point one place to the left.

2,64÷10=0,2642,64 \div 10 = 0,264

The answer is 0,264\boxed{0,264}.

Part 1.30,9734

To divide by 1000, move the decimal point three places to the left.

973,4÷1000=0,9734973,4 \div 1000 = 0,9734

The answer is 0,9734\boxed{0,9734}.

Part 1.40,0576

To divide by 100, move the decimal point two places to the left.

5,76÷100=0,05765,76 \div 100 = 0,0576

The answer is 0,0576\boxed{0,0576}.

Part 2.39,82

  1. Set up the long division.

    9.829)88.38‾\begin{array}{r} 9.82 \\ 9 \overline{\smash{)} 88.38 } \\ \end{array}

  2. Divide 88 by 9.

    9×9=819 \times 9 = 81.

    9.9)88.38‾−81↓7\begin{array}{r} 9. \\ 9 \overline{\smash{)} 88.38 } \\ -81 \downarrow \\ \hline 7 \\ \end{array}

  3. Bring down the next digit (3) after the decimal point.

    Place the decimal point in the quotient. Divide 73 by 9. 9×8=729 \times 8 = 72.

    9.89)88.38‾−81↓73−72↓1\begin{array}{r} 9.8 \\ 9 \overline{\smash{)} 88.38 } \\ -81 \downarrow \\ \hline 73 \\ -72 \downarrow \\ \hline 1 \\ \end{array}

  4. Bring down the next digit (8).

    Divide 18 by 9. 9×2=189 \times 2 = 18.

    9.829)88.38‾−81↓73−72↓18−180\begin{array}{r} 9.82 \\ 9 \overline{\smash{)} 88.38 } \\ -81 \downarrow \\ \hline 73 \\ -72 \downarrow \\ \hline 18 \\ -18 \\ \hline 0 \\ \end{array}

    The answer is 9,82\boxed{9,82}.

Part 2.43,61

  1. Set up the long division.

    3.6112)43.32‾\begin{array}{r} 3.61 \\ 12 \overline{\smash{)} 43.32 } \\ \end{array}

  2. Divide 43 by 12.

    12×3=3612 \times 3 = 36.

    3.12)43.32‾−36↓7\begin{array}{r} 3. \\ 12 \overline{\smash{)} 43.32 } \\ -36 \downarrow \\ \hline 7 \\ \end{array}

  3. Bring down the next digit (3) after the decimal point.

    Place the decimal point in the quotient. Divide 73 by 12. 12×6=7212 \times 6 = 72.

    3.612)43.32‾−36↓73−72↓1\begin{array}{r} 3.6 \\ 12 \overline{\smash{)} 43.32 } \\ -36 \downarrow \\ \hline 73 \\ -72 \downarrow \\ \hline 1 \\ \end{array}

  4. Bring down the next digit (2).

    Divide 12 by 12. 12×1=1212 \times 1 = 12.

    3.6112)43.32‾−36↓73−72↓12−120\begin{array}{r} 3.61 \\ 12 \overline{\smash{)} 43.32 } \\ -36 \downarrow \\ \hline 73 \\ -72 \downarrow \\ \hline 12 \\ -12 \\ \hline 0 \\ \end{array}

    The answer is 3,61\boxed{3,61}.
