A number divisible by 123456789 must be 0 or bigger than 123456789. It must, therefore have 1 digit or 9 digits (or more). A remainder of 1 makes no difference to the number of digits. In any case, there can be no number of 4 digits that is divisible by 123456789.
There are 504 such numbers.
Just add up the digits and if that sum is divisible by 9 then the original number is divisible by 9. Example 729 = 7+2+9 = 18 (18 is divisible by 9 therefore 729 is divisible by 9) 123456789 = 1+2+3+4+5+6+7+8+9 = 45 (45 is divisible by 9 therefore 123456789 is divisible by 9)
