I'm trying to write a program that will accept a long integer as in[put and remove the last digit...click message for more info

Step 1 Enter the ticket number; for example, 123454. Step 2 Remove the last digit, leaving 12345. Step 3 Determine the remainder when the ticket number is divided by 7. In this case, 12345 divided by 7 leaves a remainder of 4. Step 4 Assign the Boolean value of the comparison between the remainder and the digit dropped from the ticket number. Step 5 Display the result—true or false—in a message box.

Removing last digit can be done by dividing the number by 10. Finding the final digit can easily be done with: number % 10. Remainder after dividing by 7 is just number % 7. Compare the final digit with the remainder. Then your basically Done. ✔

From what I can see, this is pretty straight forward... except for removing the last digit thing, you could hhmmmm... get the remainder of the number by dividing it by 10...
