Let's divide 511572 by 81
Our goal is to divide 511572 by 81.

Step 1:
81 can be fit into 5 0 times, resulting in a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 81

Moving on to step 2:
If we divide 51 by 81, we get 0 and a remainder of 51.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 51 after subtracting 0 from 51.
Include the next digit (1) from the dividend after 51, then repeat: 511 / 81

Moving on to step 3:
81 can be fit into 511 6 times, resulting in a remainder of 25.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 486 from 511 and we're left with 25.
Bring next digit (5) of the dividend behind the 25 and repeat the process: 255 / 81

Let's proceed to step 4:
81 can be fit into 255 3 times, resulting in a remainder of 12.
The next digit of our result is 3. 
Result so far: 63.0
If we take 243 away from 255, we end up with 12.
Include the next digit (7) from the dividend after 12, then repeat: 127 / 81

On to step 5:
127 divided by 81 is 1 with a remainder of 46.
Use 1 as the next digit of our solution. 
Result so far: 631.0
Subtracting 81 from 127 leaves us with 46.
Include the next digit (2) from the dividend after 46, then repeat: 462 / 81

Going ahead to step 6:
462 divided by 81 is 5 with a remainder of 57.
Write down 5 as next digit of the result. 
Result so far: 6315.0
Deduct 405 from 462 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 7:
570 divided by 81 is 7 with a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 6315.7
Deduct 567 from 570 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 8:
The number 81 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 6315.7
Subtracting 0 from 30 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 9:
81 goes into 300 3 times with a remainder of 57.
Write down 3 as next digit of the result. 
Result so far: 6315.703
If we take 243 away from 300, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 10:
When dividing 570 by 81, we get 7 with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 6315.7037
Subtract 567 from 570 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 11:
81 goes into 30 0 times with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 6315.7037
If we take 0 away from 30, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 12:
300 divided by 81 is 3 with a remainder of 57.
The number 3 becomes the next digit in our result. 
Result so far: 6315.703703
If we take 243 away from 300, we end up with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Step 13:
570 divided by 81 is 7 with a remainder of 3.
Record the quotient 7 as the next digit in the result. 
Result so far: 6315.7037037
Deduct 567 from 570 and we're left with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 14:
30 divided by 81 is 0 with a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 6315.7037037
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The quotient of the division is 6315.7037037, and the remainder is 3e-08.
