We divide 651142 by 81
We want to divide 651142 by 81.

On to step 1:
6 divided by 81 is 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Fetch the next digit (5) from the dividend, attach it to 6 and continue: 65 / 81

Step 2:
If we divide 65 by 81, we get 0 and a remainder of 65.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 65, we get 65.
Grab the next digit (1) from the dividend, add it to 65, then carry on: 651 / 81

Step 3:
The number 81 fits into 651 8 times, leaving a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 648 from 651 to get 3.
Take the next digit (1) from the dividend and append it to 3, then repeat: 31 / 81

Let's proceed to step 4:
If we divide 31 by 81, we get 0 and a remainder of 31.
Use 0 as the next digit of our solution. 
Result so far: 80.0
The remainder is 31 after subtracting 0 from 31.
Take the next digit (4) from the dividend and append it to 31, then repeat: 314 / 81

On to step 5:
314 divided by 81 is 3 with a remainder of 71.
Record the quotient 3 as the next digit in the result. 
Result so far: 803.0
Subtract 243 from 314 to get 71.
Bring next digit (2) of the dividend behind the 71 and repeat the process: 712 / 81

On to step 6:
When dividing 712 by 81, we get 8 with a remainder of 64.
The number 8 becomes the next digit in our result. 
Result so far: 8038.0
Subtracting 648 from 712 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Step 7:
81 can be fit into 640 7 times, resulting in a remainder of 73.
Record the quotient 7 as the next digit in the result. 
Result so far: 8038.7
If we subtract 567 from 640, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 8:
81 can be fit into 730 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 8038.79
Subtracting 729 from 730 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 9:
When dividing 10 by 81, we get 0 with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 8038.79
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
81 goes into 100 1 times with a remainder of 19.
Record the quotient 1 as the next digit in the result. 
Result so far: 8038.7901
If we take 81 away from 100, we end up with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

On to step 11:
The number 81 fits into 190 2 times, leaving a remainder of 28.
The next digit of our result is 2. 
Result so far: 8038.79012
If we take 162 away from 190, we end up with 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 12:
If we divide 280 by 81, we get 3 and a remainder of 37.
The next digit of our result is 3. 
Result so far: 8038.790123
Subtracting 243 from 280 leaves us with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 13:
370 divided by 81 is 4 with a remainder of 46.
The next digit of our result is 4. 
Result so far: 8038.7901234
Subtracting 324 from 370 leaves us with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 14:
460 divided by 81 is 5 with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 8038.79012345
Subtract 405 from 460 to get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

In conclusion, the division gives 8038.79012345 with a balance of 5.5e-08.
