We look at the division of 686676 by 81 
We want to figure out the number of times 686676 can be divided by 81.

Let's proceed to step 1:
81 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 81

On to step 2:
If we divide 68 by 81, we get 0 and a remainder of 68.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 68 after subtracting 0 from 68.
Append the next digit (6) from the dividend to 68 and continue with: 686 / 81

Going ahead to step 3:
When dividing 686 by 81, we get 8 with a remainder of 38.
Write down 8 as next digit of the result. 
Result so far: 8.0
The remainder is 38 after subtracting 648 from 686.
Take the next digit (6) from the dividend and append it to 38, then repeat: 386 / 81

Step 4:
When dividing 386 by 81, we get 4 with a remainder of 62.
Put 4 as the next digit of the answer. 
Result so far: 84.0
Subtracting 324 from 386 leaves us with 62.
Append the next digit (7) from the dividend to 62 and continue with: 627 / 81

On to step 5:
81 goes into 627 7 times with a remainder of 60.
The next digit of our result is 7. 
Result so far: 847.0
Deduct 567 from 627 and we're left with 60.
Grab the next digit (6) from the dividend, add it to 60, then carry on: 606 / 81

Advancing to step 6:
When dividing 606 by 81, we get 7 with a remainder of 39.
Record the quotient 7 as the next digit in the result. 
Result so far: 8477.0
Subtracting 567 from 606 leaves us 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.

On to step 7:
The number 81 fits into 390 4 times, leaving a remainder of 66.
Record the quotient 4 as the next digit in the result. 
Result so far: 8477.4
Subtract 324 from 390 to 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.

Going ahead to step 8:
81 can be fit into 660 8 times, resulting in a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 8477.48
Subtracting 648 from 660 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Going ahead to step 9:
When dividing 120 by 81, we get 1 with a remainder of 39.
Write down 1 as next digit of the result. 
Result so far: 8477.481
If we take 81 away from 120, we end up 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.

Let's proceed to step 10:
When dividing 390 by 81, we get 4 with a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 8477.4814
The remainder is 66 after subtracting 324 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 11:
When dividing 660 by 81, we get 8 with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 8477.48148
If we subtract 648 from 660, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 12:
81 goes into 120 1 times with a remainder of 39.
Put 1 as the next digit of the answer. 
Result so far: 8477.481481
The remainder is 39 after subtracting 81 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 13:
When dividing 390 by 81, we get 4 with a remainder of 66.
Put 4 as the next digit of the answer. 
Result so far: 8477.4814814
If we subtract 324 from 390, 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.

Step 14:
81 goes into 660 8 times with a remainder of 12.
Record the quotient 8 as the next digit in the result. 
Result so far: 8477.48148148
If we subtract 648 from 660, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

After the division, we end up with 8477.48148148 and a remainder of 1.2e-08.
