We're dividing 571284 by 81 
Let's see how many times 81 fits into 571284.

Going ahead to step 1:
5 divided by 81 is 0 with a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 81

Advancing to step 2:
57 divided by 81 is 0 with a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Fetch the next digit (1) from the dividend, attach it to 57 and continue: 571 / 81

On to step 3:
If we divide 571 by 81, we get 7 and a remainder of 4.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
The remainder is 4 after subtracting 567 from 571.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 81

Moving on to step 4:
The number 81 fits into 42 0 times, leaving a remainder of 42.
The number 0 becomes the next digit in our result. 
Result so far: 70.0
Subtracting 0 from 42 leaves us with 42.
Append the next digit (8) from the dividend to 42 and continue with: 428 / 81

On to step 5:
81 goes into 428 5 times with a remainder of 23.
Record the quotient 5 as the next digit in the result. 
Result so far: 705.0
If we subtract 405 from 428, we get 23.
Grab the next digit (4) from the dividend, add it to 23, then carry on: 234 / 81

Step 6:
The number 81 fits into 234 2 times, leaving a remainder of 72.
Put 2 as the next digit of the answer. 
Result so far: 7052.0
The remainder is 72 after subtracting 162 from 234.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 7:
When dividing 720 by 81, we get 8 with a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 7052.8
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.

On to step 8:
When dividing 720 by 81, we get 8 with a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 7052.88
Deduct 648 from 720 and we're left with 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 quotient of the division is 7052.88, and the remainder is 0.072.
