We look at the division of 801355 by 86 
Let's see how many times 86 fits into 801355.

Advancing to step 1:
When dividing 8 by 86, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 86

On to step 2:
86 goes into 80 0 times with a remainder of 80.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 80 to get 80.
Append the next digit (1) from the dividend to 80 and continue with: 801 / 86

Advancing to step 3:
The number 86 fits into 801 9 times, leaving a remainder of 27.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 774 from 801 leaves us with 27.
Bring next digit (3) of the dividend behind the 27 and repeat the process: 273 / 86

Let's proceed to step 4:
86 can be fit into 273 3 times, resulting in a remainder of 15.
Use 3 as the next digit of our solution. 
Result so far: 93.0
The remainder is 15 after subtracting 258 from 273.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 86

Let's proceed to step 5:
155 divided by 86 is 1 with a remainder of 69.
Put 1 as the next digit of the answer. 
Result so far: 931.0
Subtract 86 from 155 to get 69.
Take the next digit (5) from the dividend and append it to 69, then repeat: 695 / 86

Advancing to step 6:
When dividing 695 by 86, we get 8 with a remainder of 7.
Write down 8 as next digit of the result. 
Result so far: 9318.0
If we subtract 688 from 695, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
The number 86 fits into 70 0 times, leaving a remainder of 70.
Use 0 as the next digit of our solution. 
Result so far: 9318.0
Deduct 0 from 70 and we're left with 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Going ahead to step 8:
If we divide 700 by 86, we get 8 and a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 9318.08
Deduct 688 from 700 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 9:
If we divide 120 by 86, we get 1 and a remainder of 34.
The next digit of our result is 1. 
Result so far: 9318.081
If we subtract 86 from 120, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 10:
86 can be fit into 340 3 times, resulting in a remainder of 82.
Use 3 as the next digit of our solution. 
Result so far: 9318.0813
The remainder is 82 after subtracting 258 from 340.
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 11:
86 goes into 820 9 times with a remainder of 46.
The number 9 becomes the next digit in our result. 
Result so far: 9318.08139
The remainder is 46 after subtracting 774 from 820.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 12:
When dividing 460 by 86, we get 5 with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 9318.081395
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.

Advancing to step 13:
The number 86 fits into 300 3 times, leaving a remainder of 42.
Use 3 as the next digit of our solution. 
Result so far: 9318.0813953
Subtracting 258 from 300 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 14:
420 divided by 86 is 4 with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 9318.08139534
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.

The final result is 9318.08139534 with a remainder of 7.6e-08.
