We look at the division of 520945 by 81 
We want to figure out the number of times 520945 can be divided by 81.

Going ahead to step 1:
The number 81 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Take the next digit (2) from the dividend and append it to 5, then repeat: 52 / 81

On 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
The remainder is 52 after subtracting 0 from 52.
Append the next digit (0) from the dividend to 52 and continue with: 520 / 81

Going ahead to step 3:
81 can be fit into 520 6 times, resulting in a remainder of 34.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Subtracting 486 from 520 leaves us with 34.
Append the next digit (9) from the dividend to 34 and continue with: 349 / 81

On to step 4:
349 divided by 81 is 4 with a remainder of 25.
Use 4 as the next digit of our solution. 
Result so far: 64.0
The remainder is 25 after subtracting 324 from 349.
Append the next digit (4) from the dividend to 25 and continue with: 254 / 81

Let's proceed to step 5:
254 divided by 81 is 3 with a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 643.0
Subtract 243 from 254 to get 11.
Include the next digit (5) from the dividend after 11, then repeat: 115 / 81

Going ahead to step 6:
If we divide 115 by 81, we get 1 and a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 6431.0
Deduct 81 from 115 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 7:
81 goes into 340 4 times with a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 6431.4
Subtracting 324 from 340 leaves us with 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 8:
81 can be fit into 160 1 times, resulting in a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 6431.41
If we take 81 away from 160, we end up 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.

Going ahead to step 9:
81 goes into 790 9 times with a remainder of 61.
Record the quotient 9 as the next digit in the result. 
Result so far: 6431.419
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.

Going ahead to step 10:
When dividing 610 by 81, we get 7 with a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 6431.4197
Subtract 567 from 610 to 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.

Moving on to step 11:
430 divided by 81 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 6431.41975
Subtract 405 from 430 to get 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Advancing to step 12:
If we divide 250 by 81, we get 3 and a remainder of 7.
Use 3 as the next digit of our solution. 
Result so far: 6431.419753
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.

Going ahead to step 13:
If we divide 70 by 81, we get 0 and a remainder of 70.
Write down 0 as next digit of the result. 
Result so far: 6431.419753
If we subtract 0 from 70, we get 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 14:
When dividing 700 by 81, we get 8 with a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 6431.41975308
If we take 648 away from 700, we end up 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.

Our division results in 6431.41975308 with a remaining 5.2e-08.
