Comprobar si todos los dígitos de un número lo dividen

Dado un número n, encuentre si todos los dígitos de n lo dividen o no.
Ejemplos: 
 

Input : 128
Output : Yes
128 % 1 == 0, 128 % 2 == 0, and 128 % 8 == 0.

Input : 130
Output : No

Queremos probar si cada dígito es distinto de cero y divide el número. Por ejemplo, con 128, queremos probar d != 0 && 128 % d == 0 para d = 1, 2, 8. Para hacer eso, necesitamos iterar sobre cada dígito del número.
