We're dividing 816432 by 86 
We want to divide 816432 by 86.

Let's proceed to step 1:
If we divide 8 by 86, we get 0 and a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 86

Going ahead to step 2:
81 divided by 86 is 0 with a remainder of 81.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 81 and we're left with 81.
Fetch the next digit (6) from the dividend, attach it to 81 and continue: 816 / 86

On to step 3:
816 divided by 86 is 9 with a remainder of 42.
Write down 9 as next digit of the result. 
Result so far: 9.0
Deduct 774 from 816 and we're left with 42.
Fetch the next digit (4) from the dividend, attach it to 42 and continue: 424 / 86

Step 4:
86 can be fit into 424 4 times, resulting in a remainder of 80.
The next digit of our result is 4. 
Result so far: 94.0
If we take 344 away from 424, we end up with 80.
Grab the next digit (3) from the dividend, add it to 80, then carry on: 803 / 86

Going ahead to step 5:
803 divided by 86 is 9 with a remainder of 29.
Record the quotient 9 as the next digit in the result. 
Result so far: 949.0
If we take 774 away from 803, we end up with 29.
Fetch the next digit (2) from the dividend, attach it to 29 and continue: 292 / 86

Let's proceed to step 6:
The number 86 fits into 292 3 times, leaving a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 9493.0
The remainder is 34 after subtracting 258 from 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 7:
The number 86 fits into 340 3 times, leaving a remainder of 82.
Record the quotient 3 as the next digit in the result. 
Result so far: 9493.3
If we subtract 258 from 340, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 8:
820 divided by 86 is 9 with a remainder of 46.
Record the quotient 9 as the next digit in the result. 
Result so far: 9493.39
Subtract 774 from 820 to 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.

Moving on to step 9:
If we divide 460 by 86, we get 5 and a remainder of 30.
The next digit of our result is 5. 
Result so far: 9493.395
If we take 430 away from 460, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
300 divided by 86 is 3 with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 9493.3953
Subtract 258 from 300 to 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.

Step 11:
If we divide 420 by 86, we get 4 and a remainder of 76.
The number 4 becomes the next digit in our result. 
Result so far: 9493.39534
If we subtract 344 from 420, we 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.

On to step 12:
86 goes into 760 8 times with a remainder of 72.
Record the quotient 8 as the next digit in the result. 
Result so far: 9493.395348
If we subtract 688 from 760, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 13:
720 divided by 86 is 8 with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 9493.3953488
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 final outcome is 9493.3953488, with a leftover of 3.2e-07.
