The given equation 42 ÷ 7 = 6 is correct because when we divide 42 by 7, we get a quotient of 6. In division, we are trying to find out how many times the divisor (7) can be subtracted from the dividend (42) without resulting in a negative number. In this case, we can subtract 7 from 42 a total of 6 times, which gives us a remainder of 0. Therefore, the answer is 6.
