Henry Ernest Dudeney/Modern Puzzles/65 - Dividing by 37

by : $65$

 * Dividing by $37$
 * I want to know whether the number $49,129,308,213$ is exactly divisible by $37$,
 * or if not, what is the remainder when so divided.
 * How may I do this quite easily without any process of actual division whatever?


 * It can be done by inspection in a few seconds -- if you know how.
