We look at the division of 670315 by 81 
Our goal is to divide 670315 by 81.

Advancing to step 1:
When dividing 6 by 81, we get 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 81

Advancing to step 2:
The number 81 fits into 67 0 times, leaving a remainder of 67.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 67 to get 67.
Include the next digit (0) from the dividend after 67, then repeat: 670 / 81

Going ahead to step 3:
The number 81 fits into 670 8 times, leaving a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 648 from 670 and we're left with 22.
Append the next digit (3) from the dividend to 22 and continue with: 223 / 81

On to step 4:
81 can be fit into 223 2 times, resulting in a remainder of 61.
The number 2 becomes the next digit in our result. 
Result so far: 82.0
Subtracting 162 from 223 leaves us with 61.
Grab the next digit (1) from the dividend, add it to 61, then carry on: 611 / 81

Let's proceed to step 5:
When dividing 611 by 81, we get 7 with a remainder of 44.
Write down 7 as next digit of the result. 
Result so far: 827.0
Subtract 567 from 611 to get 44.
Fetch the next digit (5) from the dividend, attach it to 44 and continue: 445 / 81

Step 6:
The number 81 fits into 445 5 times, leaving a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 8275.0
Deduct 405 from 445 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 7:
81 goes into 400 4 times with a remainder of 76.
Record the quotient 4 as the next digit in the result. 
Result so far: 8275.4
The remainder is 76 after subtracting 324 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 8:
760 divided by 81 is 9 with a remainder of 31.
Use 9 as the next digit of our solution. 
Result so far: 8275.49
If we subtract 729 from 760, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Moving on to step 9:
When dividing 310 by 81, we get 3 with a remainder of 67.
Put 3 as the next digit of the answer. 
Result so far: 8275.493
Subtracting 243 from 310 leaves us 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.

Advancing to step 10:
The number 81 fits into 670 8 times, leaving a remainder of 22.
The number 8 becomes the next digit in our result. 
Result so far: 8275.4938
If we subtract 648 from 670, we 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 11:
When dividing 220 by 81, we get 2 with a remainder of 58.
The next digit of our result is 2. 
Result so far: 8275.49382
Subtract 162 from 220 to 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.

Advancing to step 12:
If we divide 580 by 81, we get 7 and a remainder of 13.
The number 7 becomes the next digit in our result. 
Result so far: 8275.493827
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.

Moving on to step 13:
If we divide 130 by 81, we get 1 and a remainder of 49.
The number 1 becomes the next digit in our result. 
Result so far: 8275.4938271
If we take 81 away from 130, we end up 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 14:
If we divide 490 by 81, we get 6 and a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 8275.49382716
The remainder is 4 after subtracting 486 from 490.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final outcome is 8275.49382716, with a leftover of 4e-09.
