A number that is divisible by 6 will be divisible by 2and by 3. An integer is divisible by 2 if its units digit is even. An integer is divisible by 3 if the sum of its digits is divisible by 3.
__
The given number has a units digit of 9, which is <em>not even</em>. The number cannot be made divisible by 2 for any inserted digit.
You'd have to divide it by a number that is a fraction less than one and greater than zero, without any integer in order to get a greater quotient, so no.
