Let's divide 855699 by 86
We want to figure out the number of times 855699 can be divided by 86.

On to step 1:
When dividing 8 by 86, we get 0 with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (5) from the dividend after 8, then repeat: 85 / 86

Advancing to step 2:
86 can be fit into 85 0 times, resulting in a remainder of 85.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Grab the next digit (5) from the dividend, add it to 85, then carry on: 855 / 86

On to step 3:
86 goes into 855 9 times with a remainder of 81.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we take 774 away from 855, we end up with 81.
Include the next digit (6) from the dividend after 81, then repeat: 816 / 86

On to step 4:
The number 86 fits into 816 9 times, leaving a remainder of 42.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
If we take 774 away from 816, we end up with 42.
Fetch the next digit (9) from the dividend, attach it to 42 and continue: 429 / 86

Step 5:
429 divided by 86 is 4 with a remainder of 85.
Record the quotient 4 as the next digit in the result. 
Result so far: 994.0
If we subtract 344 from 429, we get 85.
Include the next digit (9) from the dividend after 85, then repeat: 859 / 86

Advancing to step 6:
86 can be fit into 859 9 times, resulting in a remainder of 85.
Put 9 as the next digit of the answer. 
Result so far: 9949.0
Subtract 774 from 859 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 7:
86 can be fit into 850 9 times, resulting in a remainder of 76.
The next digit of our result is 9. 
Result so far: 9949.9
The remainder is 76 after subtracting 774 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Let's proceed to step 8:
If we divide 760 by 86, we get 8 and a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 9949.98
The remainder is 72 after subtracting 688 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 9:
720 divided by 86 is 8 with a remainder of 32.
Write down 8 as next digit of the result. 
Result so far: 9949.988
If we subtract 688 from 720, we get 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 result is 9949.988 with a remainder of 0.0032.
