【Question 18】
Two natural numbers are divided, the quotient is 15, and the remainder is 5. It is known that the sum of the dividend, divisor, quotient, and remainder is 2169. Find the dividend.
【Analysis and Solution】
Let the divisor be $x$, then the dividend is $15 x+5$;
$$
(15 x+5)+x+15+5=2169 \text {; }
$$

Solving for $x$ gives $x=134$;
The dividend is $15 \times 134+5=2015$.
