We look at the division of 520981 by 81 
Let's see how many times 81 fits into 520981.

On to step 1:
If we divide 5 by 81, we get 0 and a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 81

Let's proceed to step 2:
The number 81 fits into 52 0 times, leaving a remainder of 52.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 52 and we're left with 52.
Fetch the next digit (0) from the dividend, attach it to 52 and continue: 520 / 81

Advancing to step 3:
If we divide 520 by 81, we get 6 and a remainder of 34.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtract 486 from 520 to get 34.
Append the next digit (9) from the dividend to 34 and continue with: 349 / 81

Step 4:
The number 81 fits into 349 4 times, leaving a remainder of 25.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
Subtracting 324 from 349 leaves us with 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 81

On to step 5:
When dividing 258 by 81, we get 3 with a remainder of 15.
The number 3 becomes the next digit in our result. 
Result so far: 643.0
Deduct 243 from 258 and we're left with 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 81

Moving on to step 6:
When dividing 151 by 81, we get 1 with a remainder of 70.
The number 1 becomes the next digit in our result. 
Result so far: 6431.0
If we take 81 away from 151, we end up 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.

Let's proceed to step 7:
When dividing 700 by 81, we get 8 with a remainder of 52.
The number 8 becomes the next digit in our result. 
Result so far: 6431.8
Deduct 648 from 700 and we're left with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 8:
If we divide 520 by 81, we get 6 and a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 6431.86
Subtract 486 from 520 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 9:
The number 81 fits into 340 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 6431.864
The remainder is 16 after subtracting 324 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 10:
160 divided by 81 is 1 with a remainder of 79.
The number 1 becomes the next digit in our result. 
Result so far: 6431.8641
The remainder is 79 after subtracting 81 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 11:
When dividing 790 by 81, we get 9 with a remainder of 61.
Write down 9 as next digit of the result. 
Result so far: 6431.86419
If we take 729 away from 790, we end up with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Step 12:
81 can be fit into 610 7 times, resulting in a remainder of 43.
Record the quotient 7 as the next digit in the result. 
Result so far: 6431.864197
If we subtract 567 from 610, we get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

On to step 13:
81 can be fit into 430 5 times, resulting in a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 6431.8641975
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.

On to step 14:
The number 81 fits into 250 3 times, leaving a remainder of 7.
Write down 3 as next digit of the result. 
Result so far: 6431.86419753
Subtract 243 from 250 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

In conclusion, the division gives 6431.86419753 with a balance of 7e-09.
