85863 divided by 86 
We want to figure out the number of times 85863 can be divided by 86.

Let's proceed to step 1:
8 divided by 86 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 86

On to step 2:
If we divide 85 by 86, we get 0 and a remainder of 85.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 85 leaves us with 85.
Include the next digit (8) from the dividend after 85, then repeat: 858 / 86

Step 3:
The number 86 fits into 858 9 times, leaving a remainder of 84.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 774 from 858 to get 84.
Include the next digit (6) from the dividend after 84, then repeat: 846 / 86

Let's proceed to step 4:
86 goes into 846 9 times with a remainder of 72.
Write down 9 as next digit of the result. 
Result so far: 99.0
Subtract 774 from 846 to get 72.
Include the next digit (3) from the dividend after 72, then repeat: 723 / 86

Going ahead to step 5:
The number 86 fits into 723 8 times, leaving a remainder of 35.
The number 8 becomes the next digit in our result. 
Result so far: 998.0
If we take 688 away from 723, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 6:
When dividing 350 by 86, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 998.4
The remainder is 6 after subtracting 344 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
86 goes into 60 0 times with a remainder of 60.
Write down 0 as next digit of the result. 
Result so far: 998.4
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.

On to step 8:
86 goes into 600 6 times with a remainder of 84.
The next digit of our result is 6. 
Result so far: 998.406
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.

Let's proceed to step 9:
86 goes into 840 9 times with a remainder of 66.
Write down 9 as next digit of the result. 
Result so far: 998.4069
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.

Let's proceed to step 10:
86 can be fit into 660 7 times, resulting in a remainder of 58.
Put 7 as the next digit of the answer. 
Result so far: 998.40697
If we subtract 602 from 660, we get 58.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Step 11:
86 goes into 580 6 times with a remainder of 64.
The next digit of our result is 6. 
Result so far: 998.406976
The remainder is 64 after subtracting 516 from 580.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Going ahead to step 12:
When dividing 640 by 86, we get 7 with a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 998.4069767
Deduct 602 from 640 and we're left with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 13:
When dividing 380 by 86, we get 4 with a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 998.40697674
Subtract 344 from 380 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

In conclusion, the division gives 998.40697674 with a balance of 3.6e-08.
