As we all learn in grade school, you can do nearly anything in arithmetic except divide a number by zero. It’s simply mathematically impossible. In our modern world, it’s easy to take the ease of digital computing for granted. It wasn’t that long ago that you needed a large machine if you wanted to calculate arithmetic without a pen and paper. 

This video of a Facit ESA-01 classic mechanic calculator perfectly demonstrates the infinite loop error of dividing by zero. MultiGlizda published this clip in 2012, but it has only gone viral now with over 750,000 new views!
