We divide 87989 by 80
Our goal is to divide 87989 by 80.

Advancing to step 1:
The number 80 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 80

Step 2:
If we divide 87 by 80, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 80 from 87, we get 7.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 80

Advancing to step 3:
79 divided by 80 is 0 with a remainder of 79.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 79, we end up with 79.
Grab the next digit (8) from the dividend, add it to 79, then carry on: 798 / 80

Step 4:
80 can be fit into 798 9 times, resulting in a remainder of 78.
The number 9 becomes the next digit in our result. 
Result so far: 109.0
If we subtract 720 from 798, we get 78.
Include the next digit (9) from the dividend after 78, then repeat: 789 / 80

Advancing to step 5:
When dividing 789 by 80, we get 9 with a remainder of 69.
Put 9 as the next digit of the answer. 
Result so far: 1099.0
If we take 720 away from 789, we end up with 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Moving on to step 6:
690 divided by 80 is 8 with a remainder of 50.
Use 8 as the next digit of our solution. 
Result so far: 1099.8
Subtracting 640 from 690 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 7:
500 divided by 80 is 6 with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 1099.86
Subtract 480 from 500 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
80 goes into 200 2 times with a remainder of 40.
The number 2 becomes the next digit in our result. 
Result so far: 1099.862
If we subtract 160 from 200, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
80 can be fit into 400 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 1099.8625
If we take 400 away from 400, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 10:
When dividing 0 by 80, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 1099.8625
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
80 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1099.8625
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 1099.8625 with a remaining 0.0.
