We look at the division of 816105 by 86 
Let's see how many times 86 fits into 816105.

Going ahead to step 1:
86 goes into 8 0 times with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Append the next digit (1) from the dividend to 8 and continue with: 81 / 86

Let's proceed to step 2:
86 goes into 81 0 times with a remainder of 81.
Record the quotient 0 as the next digit in the result. 
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

Moving on to step 3:
86 goes into 816 9 times with a remainder of 42.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
The remainder is 42 after subtracting 774 from 816.
Take the next digit (1) from the dividend and append it to 42, then repeat: 421 / 86

On to step 4:
86 can be fit into 421 4 times, resulting in a remainder of 77.
Write down 4 as next digit of the result. 
Result so far: 94.0
If we subtract 344 from 421, we get 77.
Append the next digit (0) from the dividend to 77 and continue with: 770 / 86

Moving on to step 5:
86 goes into 770 8 times with a remainder of 82.
Write down 8 as next digit of the result. 
Result so far: 948.0
Deduct 688 from 770 and we're left with 82.
Fetch the next digit (5) from the dividend, attach it to 82 and continue: 825 / 86

Step 6:
The number 86 fits into 825 9 times, leaving a remainder of 51.
The number 9 becomes the next digit in our result. 
Result so far: 9489.0
If we take 774 away from 825, we end up with 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Going ahead to step 7:
If we divide 510 by 86, we get 5 and a remainder of 80.
Record the quotient 5 as the next digit in the result. 
Result so far: 9489.5
Subtract 430 from 510 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 8:
800 divided by 86 is 9 with a remainder of 26.
Write down 9 as next digit of the result. 
Result so far: 9489.59
Deduct 774 from 800 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 9:
When dividing 260 by 86, we get 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 9489.593
The remainder is 2 after subtracting 258 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 10:
86 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 9489.593
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 11:
200 divided by 86 is 2 with a remainder of 28.
The next digit of our result is 2. 
Result so far: 9489.59302
If we subtract 172 from 200, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 12:
If we divide 280 by 86, we get 3 and a remainder of 22.
Use 3 as the next digit of our solution. 
Result so far: 9489.593023
Subtracting 258 from 280 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 13:
When dividing 220 by 86, we get 2 with a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 9489.5930232
Subtracting 172 from 220 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 14:
86 goes into 480 5 times with a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 9489.59302325
If we subtract 430 from 480, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

The final outcome is 9489.59302325, with a leftover of 5e-08.
