Example: Check to see if 203 is divisible by 7. 1  double the last digit: 3 x 2 = 6. 2  subtract that from the rest of the number: 20 - 6 = 14. 3  check to see if the difference is divisible by 7: 14 is divisible by 7, therefore 203 is also divisible by 7.he number is divisible by both 2 and 3. 6. To find out if a number is divisible by seven, take the last digit, double it, and subtract it from the rest of the number. If you get an answer divisible by 7 (including zero), then the original number is divisible by seven.
