We look at the division of 868549 by 86 
Our goal is to divide 868549 by 86.

On to step 1:
86 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Fetch the next digit (6) from the dividend, attach it to 8 and continue: 86 / 86

Step 2:
When dividing 86 by 86, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 86 from 86 and we're left with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 86

Step 3:
8 divided by 86 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 86

Moving on to step 4:
85 divided by 86 is 0 with a remainder of 85.
Put 0 as the next digit of the answer. 
Result so far: 100.0
Deduct 0 from 85 and we're left with 85.
Grab the next digit (4) from the dividend, add it to 85, then carry on: 854 / 86

Let's proceed to step 5:
The number 86 fits into 854 9 times, leaving a remainder of 80.
The number 9 becomes the next digit in our result. 
Result so far: 1009.0
If we subtract 774 from 854, we get 80.
Append the next digit (9) from the dividend to 80 and continue with: 809 / 86

Advancing to step 6:
86 can be fit into 809 9 times, resulting in a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 10099.0
Subtract 774 from 809 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 7:
When dividing 350 by 86, we get 4 with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 10099.4
Subtract 344 from 350 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 8:
86 goes into 60 0 times with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 10099.4
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 9:
86 goes into 600 6 times with a remainder of 84.
The next digit of our result is 6. 
Result so far: 10099.406
The remainder is 84 after subtracting 516 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Step 10:
86 can be fit into 840 9 times, resulting in a remainder of 66.
Write down 9 as next digit of the result. 
Result so far: 10099.4069
Subtract 774 from 840 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 11:
86 goes into 660 7 times with a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 10099.40697
Subtracting 602 from 660 leaves us with 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Moving on to step 12:
86 goes into 580 6 times with a remainder of 64.
The next digit of our result is 6. 
Result so far: 10099.406976
If we subtract 516 from 580, we get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 13:
86 goes into 640 7 times with a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 10099.4069767
The remainder is 38 after subtracting 602 from 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

On to step 14:
86 goes into 380 4 times with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 10099.40697674
Deduct 344 from 380 and we're left with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 10099.40697674, with a leftover of 3.6e-08.
