681431 divided by 81 
We want to figure out the number of times 681431 can be divided by 81.

Moving on to step 1:
If we divide 6 by 81, we get 0 and a remainder of 6.
Write down 0 as next digit of 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:
If we divide 68 by 81, we get 0 and a remainder of 68.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 68 to get 68.
Grab the next digit (1) from the dividend, add it to 68, then carry on: 681 / 81

Let's proceed to step 3:
81 goes into 681 8 times with a remainder of 33.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 648 from 681 and we're left with 33.
Bring next digit (4) of the dividend behind the 33 and repeat the process: 334 / 81

Step 4:
The number 81 fits into 334 4 times, leaving a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 84.0
The remainder is 10 after subtracting 324 from 334.
Bring next digit (3) of the dividend behind the 10 and repeat the process: 103 / 81

Going ahead to step 5:
The number 81 fits into 103 1 times, leaving a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 841.0
If we take 81 away from 103, we end up with 22.
Fetch the next digit (1) from the dividend, attach it to 22 and continue: 221 / 81

Step 6:
The number 81 fits into 221 2 times, leaving a remainder of 59.
Write down 2 as next digit of the result. 
Result so far: 8412.0
If we take 162 away from 221, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

On to step 7:
When dividing 590 by 81, we get 7 with a remainder of 23.
Use 7 as the next digit of our solution. 
Result so far: 8412.7
Subtracting 567 from 590 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Advancing to step 8:
When dividing 230 by 81, we get 2 with a remainder of 68.
The number 2 becomes the next digit in our result. 
Result so far: 8412.72
If we take 162 away from 230, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 9:
81 goes into 680 8 times with a remainder of 32.
The number 8 becomes the next digit in our result. 
Result so far: 8412.728
The remainder is 32 after subtracting 648 from 680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 10:
If we divide 320 by 81, we get 3 and a remainder of 77.
Use 3 as the next digit of our solution. 
Result so far: 8412.7283
If we subtract 243 from 320, we get 77.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

Step 11:
81 can be fit into 770 9 times, resulting in a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 8412.72839
The remainder is 41 after subtracting 729 from 770.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 12:
When dividing 410 by 81, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 8412.728395
Subtracting 405 from 410 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 13:
When dividing 50 by 81, we get 0 with a remainder of 50.
Write down 0 as next digit of the result. 
Result so far: 8412.728395
Subtracting 0 from 50 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.

Advancing to step 14:
500 divided by 81 is 6 with a remainder of 14.
Record the quotient 6 as the next digit in the result. 
Result so far: 8412.72839506
If we take 486 away from 500, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

After the division, we end up with 8412.72839506 and a remainder of 1.4e-08.
