A student asks why she should learn the standard long division algorithm if she can get a correct answer using repeated subtraction. How do you respond?

Choose the correct answer below.

A$.$ The long division algorithm is always more efficient than the repeated ction algorithm, especially when dividing large multiples of the divisor.

B$.$ If the repeated subtraction algorithm is done with large multiples of $t$ the repeated subtraction can be quite efficient. However, if a student uses repeated subtraction by subtracting small multiples of the divisor, the process can be very time consuming.

C$.$ It is always more efficient to use the repeated subtraction algorithm, however it is helpful to learn the long division algorithm to better understand the process of dividing large numbers.

D$.$ The repeated subtraction algorithm does not always produce the correct answer, however the long division algorithm is guaranteed to produce a correct answer.A
