Let's divide 860866 by 86
We want to figure out the number of times 860866 can be divided by 86.

On to step 1:
8 divided by 86 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 86

Moving on to step 2:
86 can be fit into 86 1 times, resulting in a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 86 from 86, we get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 86

Advancing to step 3:
If we divide 0 by 86, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we take 0 away from 0, we end up with 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 86

On to step 4:
86 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 100.0
Subtract 0 from 8 to get 8.
Take the next digit (6) from the dividend and append it to 8, then repeat: 86 / 86

Going ahead to step 5:
The number 86 fits into 86 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1001.0
Subtract 86 from 86 to get 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 86

On to step 6:
When dividing 6 by 86, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 10010.0
Subtracting 0 from 6 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
86 goes into 60 0 times with a remainder of 60.
The next digit of our result is 0. 
Result so far: 10010.0
Deduct 0 from 60 and we're left with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 8:
If we divide 600 by 86, we get 6 and a remainder of 84.
The number 6 becomes the next digit in our result. 
Result so far: 10010.06
If we subtract 516 from 600, we 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 9:
86 goes into 840 9 times with a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 10010.069
The remainder is 66 after subtracting 774 from 840.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 10:
If we divide 660 by 86, we get 7 and a remainder of 58.
Use 7 as the next digit of our solution. 
Result so far: 10010.0697
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.

Step 11:
580 divided by 86 is 6 with a remainder of 64.
The number 6 becomes the next digit in our result. 
Result so far: 10010.06976
Subtracting 516 from 580 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 12:
If we divide 640 by 86, we get 7 and a remainder of 38.
The next digit of our result is 7. 
Result so far: 10010.069767
Subtracting 602 from 640 leaves us 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:
If we divide 380 by 86, we get 4 and a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 10010.0697674
The remainder is 36 after subtracting 344 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 14:
When dividing 360 by 86, we get 4 with a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 10010.06976744
The remainder is 16 after subtracting 344 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

In conclusion, the division gives 10010.06976744 with a balance of 1.6e-08.
