We divide 579577 by 81
We want to figure out the number of times 579577 can be divided by 81.

Advancing 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
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 81

Let's proceed to step 2:
81 can be fit into 57 0 times, resulting in a remainder of 57.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 57, we get 57.
Fetch the next digit (9) from the dividend, attach it to 57 and continue: 579 / 81

Advancing to step 3:
The number 81 fits into 579 7 times, leaving a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 7.0
Subtracting 567 from 579 leaves us with 12.
Append the next digit (5) from the dividend to 12 and continue with: 125 / 81

Step 4:
81 goes into 125 1 times with a remainder of 44.
Use 1 as the next digit of our solution. 
Result so far: 71.0
The remainder is 44 after subtracting 81 from 125.
Grab the next digit (7) from the dividend, add it to 44, then carry on: 447 / 81

Moving on to step 5:
447 divided by 81 is 5 with a remainder of 42.
The number 5 becomes the next digit in our result. 
Result so far: 715.0
The remainder is 42 after subtracting 405 from 447.
Take the next digit (7) from the dividend and append it to 42, then repeat: 427 / 81

On to step 6:
81 can be fit into 427 5 times, resulting in a remainder of 22.
Record the quotient 5 as the next digit in the result. 
Result so far: 7155.0
Deduct 405 from 427 and we're left with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 7:
If we divide 220 by 81, we get 2 and a remainder of 58.
The number 2 becomes the next digit in our result. 
Result so far: 7155.2
The remainder is 58 after subtracting 162 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 8:
81 can be fit into 580 7 times, resulting in a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 7155.27
The remainder is 13 after subtracting 567 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 9:
When dividing 130 by 81, we get 1 with a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 7155.271
Deduct 81 from 130 and we're left with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 10:
When dividing 490 by 81, we get 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 7155.2716
Deduct 486 from 490 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
81 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 7155.2716
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 12:
The number 81 fits into 400 4 times, leaving a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 7155.271604
Deduct 324 from 400 and we're left with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 13:
81 goes into 760 9 times with a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 7155.2716049
If we take 729 away from 760, we end up with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

On to step 14:
When dividing 310 by 81, we get 3 with a remainder of 67.
Record the quotient 3 as the next digit in the result. 
Result so far: 7155.27160493
Deduct 243 from 310 and we're left with 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

The final result is 7155.27160493 with a remainder of 6.7e-08.
