Teaser 2842: The best policy

From The Sunday Times, 12th March 2017 [link]

George and Martha’s home insurance policy number is a six-figure number consisting of six different digits. George commented that the number was divisible by each of its digits and also by the sum of its digits. Martha then added that, if you deleted the left-hand digit, then you were left with a five-figure number divisible by the sum of its five digits. If you then deleted that number’s left-hand digit, then you were left with a four-figure number divisible by the sum of its four digits, and so on all the way down.

What is their policy number?
