Let's divide 866793 by 87
Our goal is to divide 866793 by 87.

Let's proceed to step 1:
8 divided by 87 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 87

Moving on to step 2:
86 divided by 87 is 0 with a remainder of 86.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 86 after subtracting 0 from 86.
Bring next digit (6) of the dividend behind the 86 and repeat the process: 866 / 87

On to step 3:
The number 87 fits into 866 9 times, leaving a remainder of 83.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 83 after subtracting 783 from 866.
Append the next digit (7) from the dividend to 83 and continue with: 837 / 87

Moving on to step 4:
When dividing 837 by 87, we get 9 with a remainder of 54.
Use 9 as the next digit of our solution. 
Result so far: 99.0
The remainder is 54 after subtracting 783 from 837.
Fetch the next digit (9) from the dividend, attach it to 54 and continue: 549 / 87

Moving on to step 5:
87 can be fit into 549 6 times, resulting in a remainder of 27.
The number 6 becomes the next digit in our result. 
Result so far: 996.0
The remainder is 27 after subtracting 522 from 549.
Grab the next digit (3) from the dividend, add it to 27, then carry on: 273 / 87

Advancing to step 6:
If we divide 273 by 87, we get 3 and a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 9963.0
The remainder is 12 after subtracting 261 from 273.
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 87, we get 1 with a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 9963.1
Subtract 87 from 120 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Let's proceed to step 8:
If we divide 330 by 87, we get 3 and a remainder of 69.
Write down 3 as next digit of the result. 
Result so far: 9963.13
Subtract 261 from 330 to get 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 690, and continue the process.

Step 9:
690 divided by 87 is 7 with a remainder of 81.
The next digit of our result is 7. 
Result so far: 9963.137
If we subtract 609 from 690, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 10:
810 divided by 87 is 9 with a remainder of 27.
Use 9 as the next digit of our solution. 
Result so far: 9963.1379
If we take 783 away from 810, we end up with 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 11:
270 divided by 87 is 3 with a remainder of 9.
The number 3 becomes the next digit in our result. 
Result so far: 9963.13793
Deduct 261 from 270 and we're left with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 12:
When dividing 90 by 87, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 9963.137931
Subtracting 87 from 90 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 13:
The number 87 fits into 30 0 times, leaving a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 9963.137931
Subtract 0 from 30 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

On to step 14:
If we divide 300 by 87, we get 3 and a remainder of 39.
The next digit of our result is 3. 
Result so far: 9963.13793103
If we take 261 away from 300, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The final outcome is 9963.13793103, with a leftover of 3.9e-08.
