REM Program to check if a number is divisible by 5 or not
CLS
INPUT "Enter a number: "; n
IF n MOD 5 = 0 THEN
  PRINT n;" is divisible by 5"
ELSE 
  PRINT n;" is not divisible by 5"  
END IF
END

Explanation

To check if a number is divisible by any number, we will be using the modulo operator (MOD). In this program, we need to check if the number is divisible by 5 or not, so we need to execute modulo division of the number by 5 i.e., n MOD 5. The modulo division returns a remainder 0 if the number is divisible and greater than 0 if the number is not divisible.

Hence, if the modulo division of number n by 5 returns 0 then display the number is divisible by 5 else not divisible by 5.
