Modern Puzzles by Henry Ernest Dudeney: $65$

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.
