We're dividing 685222 by 81 
We want to divide 685222 by 81.

Let's proceed to step 1:
The number 81 fits into 6 0 times, leaving a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 81

Going ahead to step 2:
81 can be fit into 68 0 times, resulting in a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Take the next digit (5) from the dividend and append it to 68, then repeat: 685 / 81

Moving on to step 3:
If we divide 685 by 81, we get 8 and a remainder of 37.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 648 from 685, we get 37.
Fetch the next digit (2) from the dividend, attach it to 37 and continue: 372 / 81

Going ahead to step 4:
372 divided by 81 is 4 with a remainder of 48.
Write down 4 as next digit of the result. 
Result so far: 84.0
Deduct 324 from 372 and we're left with 48.
Grab the next digit (2) from the dividend, add it to 48, then carry on: 482 / 81

Going ahead to step 5:
The number 81 fits into 482 5 times, leaving a remainder of 77.
Put 5 as the next digit of the answer. 
Result so far: 845.0
Subtracting 405 from 482 leaves us with 77.
Append the next digit (2) from the dividend to 77 and continue with: 772 / 81

Moving on to step 6:
772 divided by 81 is 9 with a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 8459.0
If we take 729 away from 772, we end up with 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Going ahead to step 7:
81 can be fit into 430 5 times, resulting in a remainder of 25.
The number 5 becomes the next digit in our result. 
Result so far: 8459.5
Subtracting 405 from 430 leaves us with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 8:
The number 81 fits into 250 3 times, leaving a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 8459.53
If we take 243 away from 250, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 9:
70 divided by 81 is 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 8459.53
Deduct 0 from 70 and we're left 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.

On to step 10:
81 can be fit into 700 8 times, resulting in a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 8459.5308
The remainder is 52 after subtracting 648 from 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

On to step 11:
When dividing 520 by 81, we get 6 with a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 8459.53086
The remainder is 34 after subtracting 486 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 12:
The number 81 fits into 340 4 times, leaving a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 8459.530864
If we subtract 324 from 340, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
81 goes into 160 1 times with a remainder of 79.
Write down 1 as next digit of the result. 
Result so far: 8459.5308641
Subtracting 81 from 160 leaves us with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 14:
The number 81 fits into 790 9 times, leaving a remainder of 61.
Use 9 as the next digit of our solution. 
Result so far: 8459.53086419
Subtract 729 from 790 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

After the division, we end up with 8459.53086419 and a remainder of 6.1e-08.
