80876809 divided by 71 
We want to figure out the number of times 80876809 can be divided by 71.

Step 1:
When dividing 8 by 71, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 71

Advancing to step 2:
71 can be fit into 80 1 times, resulting in a remainder of 9.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 71 from 80 and we're left with 9.
Include the next digit (8) from the dividend after 9, then repeat: 98 / 71

Step 3:
98 divided by 71 is 1 with a remainder of 27.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 27 after subtracting 71 from 98.
Grab the next digit (7) from the dividend, add it to 27, then carry on: 277 / 71

Moving on to step 4:
The number 71 fits into 277 3 times, leaving a remainder of 64.
Write down 3 as next digit of the result. 
Result so far: 113.0
If we take 213 away from 277, we end up with 64.
Append the next digit (6) from the dividend to 64 and continue with: 646 / 71

Going ahead to step 5:
71 goes into 646 9 times with a remainder of 7.
Record the quotient 9 as the next digit in the result. 
Result so far: 1139.0
Subtracting 639 from 646 leaves us with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 71

Advancing to step 6:
71 can be fit into 78 1 times, resulting in a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 11391.0
Subtract 71 from 78 to get 7.
Grab the next digit (0) from the dividend, add it to 7, then carry on: 70 / 71

Step 7:
71 can be fit into 70 0 times, resulting in a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 113910.0
Subtract 0 from 70 to get 70.
Grab the next digit (9) from the dividend, add it to 70, then carry on: 709 / 71

Advancing to step 8:
71 goes into 709 9 times with a remainder of 70.
The number 9 becomes the next digit in our result. 
Result so far: 1139109.0
If we take 639 away from 709, we end up with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Advancing to step 9:
700 divided by 71 is 9 with a remainder of 61.
The number 9 becomes the next digit in our result. 
Result so far: 1139109.9
The remainder is 61 after subtracting 639 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 10:
610 divided by 71 is 8 with a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 1139109.98
Deduct 568 from 610 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 11:
If we divide 420 by 71, we get 5 and a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 1139109.985
Subtracting 355 from 420 leaves us with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 12:
650 divided by 71 is 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 1139109.9859
If we subtract 639 from 650, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 13:
If we divide 110 by 71, we get 1 and a remainder of 39.
Record the quotient 1 as the next digit in the result. 
Result so far: 1139109.98591
Deduct 71 from 110 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 14:
390 divided by 71 is 5 with a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 1139109.985915
Subtract 355 from 390 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 15:
When dividing 350 by 71, we get 4 with a remainder of 66.
Write down 4 as next digit of the result. 
Result so far: 1139109.9859154
If we subtract 284 from 350, we get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 16:
The number 71 fits into 660 9 times, leaving a remainder of 21.
Put 9 as the next digit of the answer. 
Result so far: 1139109.98591549
Deduct 639 from 660 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

After the division, we end up with 1139109.98591549 and a remainder of 2.1e-08.
