We look at the division of 80686193 by 131 
We want to divide 80686193 by 131.

On to step 1:
131 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 131

On to step 2:
80 divided by 131 is 0 with a remainder of 80.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 80 and we're left with 80.
Append the next digit (6) from the dividend to 80 and continue with: 806 / 131

Let's proceed to step 3:
806 divided by 131 is 6 with a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
If we subtract 786 from 806, we get 20.
Take the next digit (8) from the dividend and append it to 20, then repeat: 208 / 131

Let's proceed to step 4:
When dividing 208 by 131, we get 1 with a remainder of 77.
Put 1 as the next digit of the answer. 
Result so far: 61.0
Subtract 131 from 208 to get 77.
Fetch the next digit (6) from the dividend, attach it to 77 and continue: 776 / 131

Going ahead to step 5:
If we divide 776 by 131, we get 5 and a remainder of 121.
Put 5 as the next digit of the answer. 
Result so far: 615.0
Subtracting 655 from 776 leaves us with 121.
Bring next digit (1) of the dividend behind the 121 and repeat the process: 1211 / 131

Advancing to step 6:
When dividing 1211 by 131, we get 9 with a remainder of 32.
Record the quotient 9 as the next digit in the result. 
Result so far: 6159.0
If we take 1179 away from 1211, we end up with 32.
Include the next digit (9) from the dividend after 32, then repeat: 329 / 131

Moving on to step 7:
When dividing 329 by 131, we get 2 with a remainder of 67.
Put 2 as the next digit of the answer. 
Result so far: 61592.0
Subtracting 262 from 329 leaves us with 67.
Grab the next digit (3) from the dividend, add it to 67, then carry on: 673 / 131

Let's proceed to step 8:
If we divide 673 by 131, we get 5 and a remainder of 18.
The number 5 becomes the next digit in our result. 
Result so far: 615925.0
If we subtract 655 from 673, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 9:
180 divided by 131 is 1 with a remainder of 49.
Put 1 as the next digit of the answer. 
Result so far: 615925.1
Subtract 131 from 180 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 10:
If we divide 490 by 131, we get 3 and a remainder of 97.
Use 3 as the next digit of our solution. 
Result so far: 615925.13
Subtracting 393 from 490 leaves us with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Going ahead to step 11:
131 can be fit into 970 7 times, resulting in a remainder of 53.
Record the quotient 7 as the next digit in the result. 
Result so far: 615925.137
Subtracting 917 from 970 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 12:
131 can be fit into 530 4 times, resulting in a remainder of 6.
The next digit of our result is 4. 
Result so far: 615925.1374
If we take 524 away from 530, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 13:
When dividing 60 by 131, we get 0 with a remainder of 60.
Use 0 as the next digit of our solution. 
Result so far: 615925.1374
If we take 0 away from 60, we end up with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Moving on to step 14:
131 can be fit into 600 4 times, resulting in a remainder of 76.
The next digit of our result is 4. 
Result so far: 615925.137404
Deduct 524 from 600 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 15:
131 can be fit into 760 5 times, resulting in a remainder of 105.
Use 5 as the next digit of our solution. 
Result so far: 615925.1374045
If we take 655 away from 760, we end up with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

On to step 16:
131 goes into 1050 8 times with a remainder of 2.
The number 8 becomes the next digit in our result. 
Result so far: 615925.13740458
Deduct 1048 from 1050 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Our division results in 615925.13740458 with a remaining 2e-09.
