Suppose when \( m \) is divided by \( n \), the quotient is \( q \) and the remainder is \( r \)....

Suppose when \( m \) is divided by \( n \), the quotient is \( q \) and the remainder is \( r \). So we can say that \( m=n q+r \), for every \( m \),
\( \mathrm{P} \)
\( n, q, r \) are integers and \( n \) is non-zero.
