Division can be done using repeated subtraction by repeatedly subtracting the divisor from the dividend until reaching zero. For example, to divide 12 by 2, one would repeatedly subtract 2 from 12 until reaching 0, with the number of subtractions equaling the quotient. A calculator can perform this repeated subtraction automatically without needing to count, displaying the zero result and number of subtractions performed.

1. A) Division using Repeated Subtraction
Example: Solve 12 ÷ 2 using repeated subtraction
Method: Take away by 2 until it gets zero result.
12 – 2 = 10
10 – 2 = 8
8 – 2 = 6
6 – 2 = 4
4 – 2 = 2
2 – 2 = 0
Therefore, 12 ÷ 2 = 6
B) How the calculator skip reading and counting?
For example, key in 12 – 6 on the calculator then press “=” continuously until it displays
zero result.
Count how many times it is subtracted by
2?
Answer: There are six 2s.
