Oh, dude, it's like this magical thing called division. So, when you divide 1428 by 14, you're basically splitting up 1428 into 14 equal parts, and each part ends up being 102. It's like cutting a Pizza into 14 slices and each slice magically becomes 102 calories, or in this case, 102.
No. 102 can be divided (exactly) by neither 14 nor 12.
