D. 123

Answer

To solve the problem of dividing 20.91 by 0.17, we can follow these steps:

### Step-by-Step Solution:

1. **Convert the Division to a Whole Number**:
We can eliminate the decimals by multiplying both the numerator (20.91) and the denominator (0.17) by 100. This gives us:
\[ \frac{20.91 \times 100}{0.17 \times 100} = \frac{2091}{17} \]

2. **Set Up Long Division**:
Now we need to divide 2091 by 17 using long division.

3. **Divide the First Part**:
- 17 goes into 20 (the first two digits of 2091) 1 time.
- Multiply 1 by 17 to get 17.
- Subtract 17 from 20 to get 3.
- Bring down the next digit (9) to make it 39.

4. **Continue Dividing**:
- 17 goes into 39 two times (since 17 x 2 = 34).
- Subtract 34 from 39 to get 5.
- Bring down the next digit (1) to make it 51.

5. **Final Division**:
- 17 goes into 51 three times (since 17 x 3 = 51).
- Subtract 51 from 51 to get 0.

6. **Combine the Results**:
- The result of the division is 123.

### Final Answer:
Thus, the value of \( 20.91 \div 0.17 \) is **123**.
