Which answer choice is not a correct method to illustrate the answer to this problem? 876 divided by 43

To solve the problem of dividing 876 by 43, let's first calculate the quotient:

\[
876 \div 43 = 20.37
\]

Since the quotient is approximately 20.37, let's look at possible methods to illustrate or represent this division problem. Typically, some methods include:

1. **Long division**: This method shows the process of division step by step.
2. **Using a calculator**: Inputting \(876 \div 43\) into a calculator will give the result directly.
3. **Estimation**: Rounding the numbers and dividing approximately, for instance, \( 880 \div 40 = 22 \), which gives an idea close to the actual result.
4. **Repeating subtraction**: Repeatedly subtracting 43 from 876 until you reach a number smaller than 43. This can also show how many times 43 fits into 876.
5. **Multiplying to check**: Multiplying 43 by various integers (like 20) to see how close the product gets to 876.

Now, the question asks which of these is **not** a correct method to illustrate the problem. The following would be invalid:

- **Using an unrelated or incorrect method**: For example, using addition or multiplication alone to represent a division problem would not be correct.

Based on this, the answer choice that is **not** correct might involve a method that isn't tied to division (like simple addition), or an incorrect result (like using the wrong numbers).
