We're dividing 622557 by 81 
We're looking to find how many times 81 goes into 622557.

Step 1:
The number 81 fits into 6 0 times, leaving a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 81

Step 2:
If we divide 62 by 81, we get 0 and a remainder of 62.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 62 after subtracting 0 from 62.
Include the next digit (2) from the dividend after 62, then repeat: 622 / 81

Let's proceed to step 3:
81 goes into 622 7 times with a remainder of 55.
Put 7 as the next digit of the answer. 
Result so far: 7.0
If we take 567 away from 622, we end up with 55.
Fetch the next digit (5) from the dividend, attach it to 55 and continue: 555 / 81

Let's proceed to step 4:
555 divided by 81 is 6 with a remainder of 69.
Write down 6 as next digit of the result. 
Result so far: 76.0
The remainder is 69 after subtracting 486 from 555.
Take the next digit (5) from the dividend and append it to 69, then repeat: 695 / 81

Going ahead to step 5:
81 goes into 695 8 times with a remainder of 47.
Use 8 as the next digit of our solution. 
Result so far: 768.0
If we take 648 away from 695, we end up with 47.
Append the next digit (7) from the dividend to 47 and continue with: 477 / 81

Advancing to step 6:
81 goes into 477 5 times with a remainder of 72.
The number 5 becomes the next digit in our result. 
Result so far: 7685.0
If we subtract 405 from 477, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Let's proceed to step 7:
81 goes into 720 8 times with a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 7685.8
If we subtract 648 from 720, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 8:
720 divided by 81 is 8 with a remainder of 72.
The number 8 becomes the next digit in our result. 
Result so far: 7685.88
Subtract 648 from 720 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

The final result is 7685.88 with a remainder of 0.072.
