    0.81 (repeated 81) (On paper, raw a straight line above the 8 and 1)

    Step-by-step explanation:

    To divide by long division to get a decimal number, you divide normally. For the decimals after "9", add some 0's. Follow the long division process, which you remember with DMS↓. (Divide, multiply, subtract, down).

    This is the set up:

    11 ∫9.0000

    Here are the first few steps:

    Divide: (11 goes into 9 "0" times. Write "0" in the answer place directly above the "9").

    0.

    11 ∫9.0000

    Multiply the last used digit in answer by 11. (0 X 11 = 0. Write the answer under "9").

    0.

    11 ∫9.0000

    0

    Subtract under the original division question. (9 - 0 = 9)

    0.

    11 ∫9.0000

    - 0

    9

    Down ↓. Bring down the next digit from the question.

    0.

    11 ∫9.0000

    - 0 ↓

    9 0

    Now start the process again.

    Divide. (Divide 11 by 90. It goes in 8 times with remainders. Write "8" in the answer.)

    0.8

    11 ∫9.0000

    - 0 ↓

    9 0

    Multiply. (Multiply 8 and 11, write the product under 90.)

    0.8

    11 ∫9.0000

    - 0 ↓

    9 0

    8 8

    Multiply. (Subtract 88 from 90.)

    0.8

    11 ∫9.0000

    - 0 ↓

    9 0

    - 8 8

    2

    Repeat the process until you end up subtracting 0s, or until you get repeating decimals.

    The final looks like this:

    0.8 181 Decimal is going to repeat.

    11 ∫9.0000

    - 0 ↓

    9 0

    - 8 8 ↓

    2 0

    - 1 1 ↓

    9 0

    - 8 8 ↓

    2 0
