858761 divided by 86 
We want to figure out the number of times 858761 can be divided by 86.

On 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
The remainder is 8 after subtracting 0 from 8.
Bring next digit (5) of the dividend behind the 8 and repeat the process: 85 / 86

Advancing to step 2:
86 can be fit into 85 0 times, resulting in a remainder of 85.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 85 to get 85.
Take the next digit (8) from the dividend and append it to 85, then repeat: 858 / 86

Advancing to step 3:
86 can be fit into 858 9 times, resulting in a remainder of 84.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtracting 774 from 858 leaves us with 84.
Append the next digit (7) from the dividend to 84 and continue with: 847 / 86

On to step 4:
847 divided by 86 is 9 with a remainder of 73.
Record the quotient 9 as the next digit in the result. 
Result so far: 99.0
If we take 774 away from 847, we end up with 73.
Grab the next digit (6) from the dividend, add it to 73, then carry on: 736 / 86

Advancing to step 5:
If we divide 736 by 86, we get 8 and a remainder of 48.
Write down 8 as next digit of the result. 
Result so far: 998.0
Subtract 688 from 736 to get 48.
Fetch the next digit (1) from the dividend, attach it to 48 and continue: 481 / 86

Let's proceed to step 6:
When dividing 481 by 86, we get 5 with a remainder of 51.
Write down 5 as next digit of the result. 
Result so far: 9985.0
If we subtract 430 from 481, we get 51.
Since there are no more digits in the dividend, we add a zero to the remainder making it 510, and continue the process.

Let's proceed to step 7:
If we divide 510 by 86, we get 5 and a remainder of 80.
Write down 5 as next digit of the result. 
Result so far: 9985.5
Subtract 430 from 510 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Moving on to step 8:
86 goes into 800 9 times with a remainder of 26.
The next digit of our result is 9. 
Result so far: 9985.59
Deduct 774 from 800 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

On to step 9:
86 can be fit into 260 3 times, resulting in a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 9985.593
If we take 258 away from 260, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
86 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 9985.593
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 11:
200 divided by 86 is 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 9985.59302
If we subtract 172 from 200, we get 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Advancing to step 12:
280 divided by 86 is 3 with a remainder of 22.
The number 3 becomes the next digit in our result. 
Result so far: 9985.593023
Subtract 258 from 280 to get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

On to step 13:
86 can be fit into 220 2 times, resulting in a remainder of 48.
The next digit of our result is 2. 
Result so far: 9985.5930232
Subtract 172 from 220 to get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Step 14:
The number 86 fits into 480 5 times, leaving a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 9985.59302325
Subtracting 430 from 480 leaves us with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

In conclusion, the division gives 9985.59302325 with a balance of 5e-08.
