Let's divide 855219 by 86
We want to divide 855219 by 86.

On to step 1:
86 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 86

Let's proceed to step 2:
If we divide 85 by 86, we get 0 and a remainder of 85.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 85, we end up with 85.
Grab the next digit (5) from the dividend, add it to 85, then carry on: 855 / 86

On to step 3:
When dividing 855 by 86, we get 9 with a remainder of 81.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 774 from 855 to get 81.
Bring next digit (2) of the dividend behind the 81 and repeat the process: 812 / 86

Let's proceed to step 4:
86 goes into 812 9 times with a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 99.0
Deduct 774 from 812 and we're left with 38.
Bring next digit (1) of the dividend behind the 38 and repeat the process: 381 / 86

On to step 5:
If we divide 381 by 86, we get 4 and a remainder of 37.
Write down 4 as next digit of the result. 
Result so far: 994.0
Subtracting 344 from 381 leaves us with 37.
Include the next digit (9) from the dividend after 37, then repeat: 379 / 86

Going ahead to step 6:
379 divided by 86 is 4 with a remainder of 35.
The number 4 becomes the next digit in our result. 
Result so far: 9944.0
Subtracting 344 from 379 leaves us 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.

Let's proceed to step 7:
When dividing 350 by 86, we get 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 9944.4
If we subtract 344 from 350, we 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:
The number 86 fits into 60 0 times, leaving a remainder of 60.
Record the quotient 0 as the next digit in the result. 
Result so far: 9944.4
Subtract 0 from 60 to 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 9:
86 can be fit into 600 6 times, resulting in a remainder of 84.
Write down 6 as next digit of the result. 
Result so far: 9944.406
Subtract 516 from 600 to get 84.
Since there are no more digits in the dividend, we add a zero to the remainder making it 840, and continue the process.

Moving on to step 10:
If we divide 840 by 86, we get 9 and a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 9944.4069
Deduct 774 from 840 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Going ahead to step 11:
86 goes into 660 7 times with a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 9944.40697
If we take 602 away from 660, we end up 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.

Going ahead to step 12:
If we divide 580 by 86, we get 6 and a remainder of 64.
Use 6 as the next digit of our solution. 
Result so far: 9944.406976
Subtract 516 from 580 to 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.

Step 13:
86 can be fit into 640 7 times, resulting in a remainder of 38.
The next digit of our result is 7. 
Result so far: 9944.4069767
Subtract 602 from 640 to get 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 14:
380 divided by 86 is 4 with a remainder of 36.
Write down 4 as next digit of the result. 
Result so far: 9944.40697674
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.

In conclusion, the division gives 9944.40697674 with a balance of 3.6e-08.
