858492 divided by 86 
We want to figure out the number of times 858492 can be divided by 86.

Moving on to step 1:
86 goes into 8 0 times with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 86

Moving on to step 2:
85 divided by 86 is 0 with a remainder of 85.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 85 and we're left with 85.
Grab the next digit (8) from the dividend, add it to 85, then carry on: 858 / 86

Going ahead to step 3:
If we divide 858 by 86, we get 9 and a remainder of 84.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 774 from 858 and we're left with 84.
Bring next digit (4) of the dividend behind the 84 and repeat the process: 844 / 86

Let's proceed to step 4:
If we divide 844 by 86, we get 9 and a remainder of 70.
The number 9 becomes the next digit in our result. 
Result so far: 99.0
Deduct 774 from 844 and we're left with 70.
Fetch the next digit (9) from the dividend, attach it to 70 and continue: 709 / 86

Going ahead to step 5:
When dividing 709 by 86, we get 8 with a remainder of 21.
Use 8 as the next digit of our solution. 
Result so far: 998.0
The remainder is 21 after subtracting 688 from 709.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 86

On to step 6:
The number 86 fits into 212 2 times, leaving a remainder of 40.
Record the quotient 2 as the next digit in the result. 
Result so far: 9982.0
If we take 172 away from 212, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 7:
The number 86 fits into 400 4 times, leaving a remainder of 56.
Put 4 as the next digit of the answer. 
Result so far: 9982.4
Subtract 344 from 400 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Advancing to step 8:
86 can be fit into 560 6 times, resulting in a remainder of 44.
The number 6 becomes the next digit in our result. 
Result so far: 9982.46
If we subtract 516 from 560, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 9:
86 can be fit into 440 5 times, resulting in a remainder of 10.
The next digit of our result is 5. 
Result so far: 9982.465
The remainder is 10 after subtracting 430 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 10:
When dividing 100 by 86, we get 1 with a remainder of 14.
Put 1 as the next digit of the answer. 
Result so far: 9982.4651
Subtracting 86 from 100 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 11:
If we divide 140 by 86, we get 1 and a remainder of 54.
Write down 1 as next digit of the result. 
Result so far: 9982.46511
The remainder is 54 after subtracting 86 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

The final result is 9982.46511 with a remainder of 5.4e-05.
