859066 divided by 86 
Let's see how many times 86 fits into 859066.

Let's proceed to step 1:
When dividing 8 by 86, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 8 to get 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.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 85, we get 85.
Grab the next digit (9) from the dividend, add it to 85, then carry on: 859 / 86

Moving on to step 3:
The number 86 fits into 859 9 times, leaving a remainder of 85.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 774 from 859 and we're left with 85.
Include the next digit (0) from the dividend after 85, then repeat: 850 / 86

Going ahead to step 4:
86 goes into 850 9 times with a remainder of 76.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
Subtract 774 from 850 to get 76.
Append the next digit (6) from the dividend to 76 and continue with: 766 / 86

Advancing to step 5:
If we divide 766 by 86, we get 8 and a remainder of 78.
Record the quotient 8 as the next digit in the result. 
Result so far: 998.0
If we take 688 away from 766, we end up with 78.
Fetch the next digit (6) from the dividend, attach it to 78 and continue: 786 / 86

Step 6:
86 goes into 786 9 times with a remainder of 12.
Record the quotient 9 as the next digit in the result. 
Result so far: 9989.0
Deduct 774 from 786 and we're left with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 7:
When dividing 120 by 86, we get 1 with a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 9989.1
Subtracting 86 from 120 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Step 8:
340 divided by 86 is 3 with a remainder of 82.
Put 3 as the next digit of the answer. 
Result so far: 9989.13
If we take 258 away from 340, we end up with 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Moving on to step 9:
86 can be fit into 820 9 times, resulting in a remainder of 46.
Put 9 as the next digit of the answer. 
Result so far: 9989.139
If we take 774 away from 820, we end up with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 10:
The number 86 fits into 460 5 times, leaving a remainder of 30.
The next digit of our result is 5. 
Result so far: 9989.1395
The remainder is 30 after subtracting 430 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 11:
The number 86 fits into 300 3 times, leaving a remainder of 42.
Write down 3 as next digit of the result. 
Result so far: 9989.13953
The remainder is 42 after subtracting 258 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 12:
86 goes into 420 4 times with a remainder of 76.
Write down 4 as next digit of the result. 
Result so far: 9989.139534
Subtracting 344 from 420 leaves us with 76.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Moving on to step 13:
When dividing 760 by 86, we get 8 with a remainder of 72.
Use 8 as the next digit of our solution. 
Result so far: 9989.1395348
Subtracting 688 from 760 leaves us with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 14:
720 divided by 86 is 8 with a remainder of 32.
Record the quotient 8 as the next digit in the result. 
Result so far: 9989.13953488
Subtracting 688 from 720 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 9989.13953488 with a balance of 3.2e-08.
