813323 divided by 86 
Our goal is to divide 813323 by 86.

Going ahead to step 1:
If we divide 8 by 86, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 86

On to step 2:
86 can be fit into 81 0 times, resulting in a remainder of 81.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Fetch the next digit (3) from the dividend, attach it to 81 and continue: 813 / 86

Advancing to step 3:
The number 86 fits into 813 9 times, leaving a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 774 from 813 and we're left with 39.
Include the next digit (3) from the dividend after 39, then repeat: 393 / 86

Going ahead to step 4:
393 divided by 86 is 4 with a remainder of 49.
Write down 4 as next digit of the result. 
Result so far: 94.0
Subtracting 344 from 393 leaves us with 49.
Include the next digit (2) from the dividend after 49, then repeat: 492 / 86

Going ahead to step 5:
When dividing 492 by 86, we get 5 with a remainder of 62.
The number 5 becomes the next digit in our result. 
Result so far: 945.0
If we take 430 away from 492, we end up with 62.
Append the next digit (3) from the dividend to 62 and continue with: 623 / 86

Step 6:
623 divided by 86 is 7 with a remainder of 21.
Use 7 as the next digit of our solution. 
Result so far: 9457.0
Subtracting 602 from 623 leaves us with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 7:
When dividing 210 by 86, we get 2 with a remainder of 38.
Write down 2 as next digit of the result. 
Result so far: 9457.2
Subtracting 172 from 210 leaves us with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Going ahead to step 8:
86 can be fit into 380 4 times, resulting in a remainder of 36.
The next digit of our result is 4. 
Result so far: 9457.24
Subtract 344 from 380 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 9:
86 goes into 360 4 times with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 9457.244
Subtract 344 from 360 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 9457.244 with a remainder of 0.0016.
