Let's divide 866524 by 87
We're looking to find how many times 87 goes into 866524.

Advancing to step 1:
8 divided by 87 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 87

Step 2:
87 can be fit into 86 0 times, resulting in a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 86 to get 86.
Grab the next digit (6) from the dividend, add it to 86, then carry on: 866 / 87

Going ahead to step 3:
87 goes into 866 9 times with a remainder of 83.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Deduct 783 from 866 and we're left with 83.
Bring next digit (5) of the dividend behind the 83 and repeat the process: 835 / 87

On to step 4:
When dividing 835 by 87, we get 9 with a remainder of 52.
The next digit of our result is 9. 
Result so far: 99.0
Subtracting 783 from 835 leaves us with 52.
Bring next digit (2) of the dividend behind the 52 and repeat the process: 522 / 87

Let's proceed to step 5:
522 divided by 87 is 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 996.0
Subtracting 522 from 522 leaves us with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 87

Advancing to step 6:
If we divide 4 by 87, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 9960.0
If we subtract 0 from 4, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
87 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 9960.0
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 8:
The number 87 fits into 400 4 times, leaving a remainder of 52.
The number 4 becomes the next digit in our result. 
Result so far: 9960.04
If we subtract 348 from 400, we get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Going ahead to step 9:
When dividing 520 by 87, we get 5 with a remainder of 85.
The number 5 becomes the next digit in our result. 
Result so far: 9960.045
The remainder is 85 after subtracting 435 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

On to step 10:
87 goes into 850 9 times with a remainder of 67.
The number 9 becomes the next digit in our result. 
Result so far: 9960.0459
If we subtract 783 from 850, we get 67.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 11:
If we divide 670 by 87, we get 7 and a remainder of 61.
The next digit of our result is 7. 
Result so far: 9960.04597
The remainder is 61 after subtracting 609 from 670.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 12:
610 divided by 87 is 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 9960.045977
If we subtract 609 from 610, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Our division results in 9960.045977 with a remaining 1e-07.
