We're dividing 8431297 by 813 
Let's see how many times 813 fits into 8431297.

Going ahead to step 1:
8 divided by 813 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 813

On to step 2:
If we divide 84 by 813, we get 0 and a remainder of 84.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 84 leaves us with 84.
Include the next digit (3) from the dividend after 84, then repeat: 843 / 813

Moving on to step 3:
813 goes into 843 1 times with a remainder of 30.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 30 after subtracting 813 from 843.
Fetch the next digit (1) from the dividend, attach it to 30 and continue: 301 / 813

Step 4:
If we divide 301 by 813, we get 0 and a remainder of 301.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 301 leaves us with 301.
Append the next digit (2) from the dividend to 301 and continue with: 3012 / 813

Step 5:
813 goes into 3012 3 times with a remainder of 573.
The number 3 becomes the next digit in our result. 
Result so far: 103.0
If we subtract 2439 from 3012, we get 573.
Take the next digit (9) from the dividend and append it to 573, then repeat: 5739 / 813

Moving on to step 6:
813 can be fit into 5739 7 times, resulting in a remainder of 48.
Write down 7 as next digit of the result. 
Result so far: 1037.0
If we subtract 5691 from 5739, we get 48.
Take the next digit (7) from the dividend and append it to 48, then repeat: 487 / 813

Advancing to step 7:
813 can be fit into 487 0 times, resulting in a remainder of 487.
Use 0 as the next digit of our solution. 
Result so far: 10370.0
If we take 0 away from 487, we end up with 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

Let's proceed to step 8:
813 can be fit into 4870 5 times, resulting in a remainder of 805.
The number 5 becomes the next digit in our result. 
Result so far: 10370.5
If we subtract 4065 from 4870, we get 805.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8050, and continue the process.

Step 9:
When dividing 8050 by 813, we get 9 with a remainder of 733.
The number 9 becomes the next digit in our result. 
Result so far: 10370.59
If we subtract 7317 from 8050, we get 733.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7330, and continue the process.

Let's proceed to step 10:
The number 813 fits into 7330 9 times, leaving a remainder of 13.
The next digit of our result is 9. 
Result so far: 10370.599
If we take 7317 away from 7330, we end up with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

The final result is 10370.599 with a remainder of 0.0013.
