What is 91 divided by 7 in long division

what is 29 subtract 82

91 / 7

7 fits within 9 only once, so the first number is 1
you have two left over
drop the one from 91 down, so you have to figure out how many times 7 goes into 21

it goes in 3 times

so the answer is 13

   _1
7 | 91
  - 7
  
    2 1

   _13__
7 | 91
  - 7
  
    2 1
    2 1
  
      0

29 - 82
since 82 is bigger than 29, you will be getting a negative number.

 if you did 82 - 29 it would be 53   
but after you hit zero, it is 52 below zero, so the answer is -53
