So 13 divided by 3 is 4 but where is the 4 coming from because 4 groups of 3 is 12 so 13 minus 12 is 1 so how dose the 4 make it the remander

13/3= 4.25 because

13-12 is 1.

SO:

When you have your problem  set up, you have 4, and then a 1 left over. You turn it into a fraction.

Make 4 and 1/4, then put it as a mixed number, 4 1/4

or you can keep dividing by adding a decimal then zeroes and keep solving until you get 4.25 which is equivalent to 4 1/4

13 divides by 3 is not 4. You are correct of 3 times 4 is 12 not 13. 13 divided by 3 would be 3 and 1/3 since 3 can't go into 13 evenly. Hope I help you understand!
