We divide 852584 by 86
We want to divide 852584 by 86.

Advancing 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
If we subtract 0 from 8, we get 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 86

Let's proceed to step 2:
86 goes into 85 0 times with 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.
Append the next digit (2) from the dividend to 85 and continue with: 852 / 86

Let's proceed to step 3:
If we divide 852 by 86, we get 9 and a remainder of 78.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Deduct 774 from 852 and we're left with 78.
Bring next digit (5) of the dividend behind the 78 and repeat the process: 785 / 86

Let's proceed to step 4:
When dividing 785 by 86, we get 9 with a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 99.0
Deduct 774 from 785 and we're left with 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 86

On to step 5:
The number 86 fits into 118 1 times, leaving a remainder of 32.
The number 1 becomes the next digit in our result. 
Result so far: 991.0
Subtract 86 from 118 to get 32.
Fetch the next digit (4) from the dividend, attach it to 32 and continue: 324 / 86

On to step 6:
324 divided by 86 is 3 with a remainder of 66.
Use 3 as the next digit of our solution. 
Result so far: 9913.0
Subtract 258 from 324 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Step 7:
If we divide 660 by 86, we get 7 and a remainder of 58.
The number 7 becomes the next digit in our result. 
Result so far: 9913.7
The remainder is 58 after subtracting 602 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 580, and continue the process.

Let's proceed to step 8:
86 can be fit into 580 6 times, resulting in a remainder of 64.
Record the quotient 6 as the next digit in the result. 
Result so far: 9913.76
The remainder is 64 after subtracting 516 from 580.
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 9:
640 divided by 86 is 7 with a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 9913.767
If we subtract 602 from 640, we 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.

Going ahead to step 10:
86 goes into 380 4 times with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 9913.7674
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.

Step 11:
86 can be fit into 360 4 times, resulting in a remainder of 16.
The next digit of our result is 4. 
Result so far: 9913.76744
If we subtract 344 from 360, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The final result is 9913.76744 with a remainder of 1.6e-05.
