We look at the division of 671575 by 81 
Our goal is to divide 671575 by 81.

Going ahead to step 1:
81 goes into 6 0 times with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 81

Let's proceed to step 2:
The number 81 fits into 67 0 times, leaving a remainder of 67.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 67 to get 67.
Include the next digit (1) from the dividend after 67, then repeat: 671 / 81

Advancing to step 3:
The number 81 fits into 671 8 times, leaving a remainder of 23.
Put 8 as the next digit of the answer. 
Result so far: 8.0
The remainder is 23 after subtracting 648 from 671.
Bring next digit (5) of the dividend behind the 23 and repeat the process: 235 / 81

Going ahead to step 4:
235 divided by 81 is 2 with a remainder of 73.
Put 2 as the next digit of the answer. 
Result so far: 82.0
If we take 162 away from 235, we end up with 73.
Append the next digit (7) from the dividend to 73 and continue with: 737 / 81

Step 5:
If we divide 737 by 81, we get 9 and a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 829.0
If we take 729 away from 737, we end up with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 81

Going ahead to step 6:
When dividing 85 by 81, we get 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 8291.0
Deduct 81 from 85 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.

Let's proceed to step 7:
81 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 8291.0
The remainder is 40 after subtracting 0 from 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 8:
When dividing 400 by 81, we get 4 with a remainder of 76.
The next digit of our result is 4. 
Result so far: 8291.04
Subtract 324 from 400 to get 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Going ahead to step 9:
81 goes into 760 9 times with a remainder of 31.
The number 9 becomes the next digit in our result. 
Result so far: 8291.049
Subtracting 729 from 760 leaves us 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.

Going ahead to step 10:
The number 81 fits into 310 3 times, leaving a remainder of 67.
The number 3 becomes the next digit in our result. 
Result so far: 8291.0493
Subtract 243 from 310 to get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Let's proceed to step 11:
81 can be fit into 670 8 times, resulting in a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 8291.04938
Subtract 648 from 670 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 12:
The number 81 fits into 220 2 times, leaving a remainder of 58.
The next digit of our result is 2. 
Result so far: 8291.049382
If we subtract 162 from 220, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 13:
580 divided by 81 is 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 8291.0493827
If we subtract 567 from 580, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 14:
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: 8291.04938271
Subtracting 81 from 130 leaves us 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.

After the division, we end up with 8291.04938271 and a remainder of 4.9e-08.
