520073 ÷ 81 
Our goal is to divide 520073 by 81.

Let's proceed to step 1:
81 can be fit into 5 0 times, resulting in a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Grab the next digit (2) from the dividend, add it to 5, then carry on: 52 / 81

Moving on to step 2:
The number 81 fits into 52 0 times, leaving a remainder of 52.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 52, we end up with 52.
Fetch the next digit (0) from the dividend, attach it to 52 and continue: 520 / 81

On to step 3:
If we divide 520 by 81, we get 6 and a remainder of 34.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 486 from 520 and we're left with 34.
Take the next digit (0) from the dividend and append it to 34, then repeat: 340 / 81

Going ahead to step 4:
81 can be fit into 340 4 times, resulting in a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
If we subtract 324 from 340, we get 16.
Grab the next digit (7) from the dividend, add it to 16, then carry on: 167 / 81

Step 5:
If we divide 167 by 81, we get 2 and a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 642.0
The remainder is 5 after subtracting 162 from 167.
Append the next digit (3) from the dividend to 5 and continue with: 53 / 81

Step 6:
The number 81 fits into 53 0 times, leaving a remainder of 53.
Write down 0 as next digit of the result. 
Result so far: 6420.0
If we take 0 away from 53, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Advancing to step 7:
When dividing 530 by 81, we get 6 with a remainder of 44.
Use 6 as the next digit of our solution. 
Result so far: 6420.6
The remainder is 44 after subtracting 486 from 530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 8:
The number 81 fits into 440 5 times, leaving a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 6420.65
If we subtract 405 from 440, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Advancing to step 9:
The number 81 fits into 350 4 times, leaving a remainder of 26.
The next digit of our result is 4. 
Result so far: 6420.654
Subtracting 324 from 350 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 10:
260 divided by 81 is 3 with a remainder of 17.
The number 3 becomes the next digit in our result. 
Result so far: 6420.6543
Subtracting 243 from 260 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 11:
The number 81 fits into 170 2 times, leaving a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 6420.65432
If we subtract 162 from 170, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 12:
81 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 6420.65432
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Advancing to step 13:
When dividing 800 by 81, we get 9 with a remainder of 71.
The next digit of our result is 9. 
Result so far: 6420.6543209
If we subtract 729 from 800, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 14:
When dividing 710 by 81, we get 8 with a remainder of 62.
The number 8 becomes the next digit in our result. 
Result so far: 6420.65432098
Subtract 648 from 710 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

In conclusion, the division gives 6420.65432098 with a balance of 6.2e-08.
