820393 divided by 86 
Our goal is to divide 820393 by 86.

On to step 1:
86 goes into 8 0 times with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 86

Going ahead to step 2:
86 goes into 82 0 times with a remainder of 82.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 82 and we're left with 82.
Append the next digit (0) from the dividend to 82 and continue with: 820 / 86

Moving on to step 3:
820 divided by 86 is 9 with a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 46 after subtracting 774 from 820.
Grab the next digit (3) from the dividend, add it to 46, then carry on: 463 / 86

Advancing to step 4:
When dividing 463 by 86, we get 5 with a remainder of 33.
The next digit of our result is 5. 
Result so far: 95.0
Subtracting 430 from 463 leaves us with 33.
Bring next digit (9) of the dividend behind the 33 and repeat the process: 339 / 86

Let's proceed to step 5:
When dividing 339 by 86, we get 3 with a remainder of 81.
Write down 3 as next digit of the result. 
Result so far: 953.0
If we subtract 258 from 339, we get 81.
Take the next digit (3) from the dividend and append it to 81, then repeat: 813 / 86

On to step 6:
If we divide 813 by 86, we get 9 and a remainder of 39.
Record the quotient 9 as the next digit in the result. 
Result so far: 9539.0
Deduct 774 from 813 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 7:
The number 86 fits into 390 4 times, leaving a remainder of 46.
Put 4 as the next digit of the answer. 
Result so far: 9539.4
If we subtract 344 from 390, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 8:
460 divided by 86 is 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 9539.45
Subtract 430 from 460 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 9:
300 divided by 86 is 3 with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 9539.453
If we subtract 258 from 300, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 10:
86 can be fit into 420 4 times, resulting in a remainder of 76.
Use 4 as the next digit of our solution. 
Result so far: 9539.4534
Subtracting 344 from 420 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 11:
The number 86 fits into 760 8 times, leaving a remainder of 72.
Put 8 as the next digit of the answer. 
Result so far: 9539.45348
The remainder is 72 after subtracting 688 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Step 12:
When dividing 720 by 86, we get 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 9539.453488
If we take 688 away from 720, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

The quotient of the division is 9539.453488, and the remainder is 3.2e-06.
