Add 1 for the cases with the most questions, and 1 for the cases with the least questions. Quotient plus 1 may be because the formula uses a one-step method, that is, the remaining number is added to the quotient as 1, which is like saying that 52 people in a school go out and all use a van with seven people, so there are still three people left and they need a car to ride. If 1 is not entered in the quotient, it may be a tail-cutting method or an ordinary formula.

Basic explanation

The remainder refers to the undivided part of the dividend in integer division, and its value range is between 0 and divisor (excluding divisor). For example, if 27 is divided by 6, the quotient is 4 and the remainder is 3. If a number is divided by another number, if it is smaller than another number, the quotient is 0 and the remainder is itself. ? [1] For example, if 1 is divided by 2, the quotient is 0 and the remainder is1; When 2 is divided by 3, the quotient is 0 and the remainder is 2.
