We divide 520648 by 81
We're looking to find how many times 81 goes into 520648.

Step 1:
The number 81 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 81

Going ahead to step 2:
52 divided by 81 is 0 with a remainder of 52.
Put 0 as the next digit of the answer. 
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

Let's proceed to step 3:
When dividing 520 by 81, we get 6 with a remainder of 34.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 486 from 520 and we're left with 34.
Include the next digit (6) from the dividend after 34, then repeat: 346 / 81

Let's proceed to step 4:
If we divide 346 by 81, we get 4 and a remainder of 22.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
If we subtract 324 from 346, we get 22.
Grab the next digit (4) from the dividend, add it to 22, then carry on: 224 / 81

Going ahead to step 5:
If we divide 224 by 81, we get 2 and a remainder of 62.
Use 2 as the next digit of our solution. 
Result so far: 642.0
If we subtract 162 from 224, we get 62.
Append the next digit (8) from the dividend to 62 and continue with: 628 / 81

Let's proceed to step 6:
628 divided by 81 is 7 with a remainder of 61.
The number 7 becomes the next digit in our result. 
Result so far: 6427.0
Subtract 567 from 628 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.

Moving on to step 7:
The number 81 fits into 610 7 times, leaving a remainder of 43.
Write down 7 as next digit of the result. 
Result so far: 6427.7
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.

Step 8:
When dividing 430 by 81, we get 5 with a remainder of 25.
Record the quotient 5 as the next digit in the result. 
Result so far: 6427.75
If we subtract 405 from 430, we 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.

Moving on to step 9:
250 divided by 81 is 3 with a remainder of 7.
The number 3 becomes the next digit in our result. 
Result so far: 6427.753
The remainder is 7 after subtracting 243 from 250.
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 10:
When dividing 70 by 81, we get 0 with a remainder of 70.
Put 0 as the next digit of the answer. 
Result so far: 6427.753
The remainder is 70 after subtracting 0 from 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 11:
When dividing 700 by 81, we get 8 with a remainder of 52.
Write down 8 as next digit of the result. 
Result so far: 6427.75308
Subtract 648 from 700 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Let's proceed to step 12:
If we divide 520 by 81, we get 6 and a remainder of 34.
Write down 6 as next digit of the result. 
Result so far: 6427.753086
Deduct 486 from 520 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.

Advancing to step 13:
81 can be fit into 340 4 times, resulting in a remainder of 16.
Put 4 as the next digit of the answer. 
Result so far: 6427.7530864
If we take 324 away from 340, we end up 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.

Let's proceed to step 14:
160 divided by 81 is 1 with a remainder of 79.
Record the quotient 1 as the next digit in the result. 
Result so far: 6427.75308641
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.

In conclusion, the division gives 6427.75308641 with a balance of 7.9e-08.
