The remainder is 14 and the quotient is 13.

So dividend = divisor * 13+ 14.

The sum of dividend, divisor and remainder is 392.

So dividend+divisor+14=392.

So dividend+divisor =378.

Because dividend = divisor * 13+ 14

So divisor * 13+ 14+ divisor =378.

14* divider =378- 14=364

So divisor =364÷ 14=26.
