869356 divided by 87 
Let's see how many times 87 fits into 869356.

On to step 1:
87 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 87

Moving on to step 2:
When dividing 86 by 87, we get 0 with a remainder of 86.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 86, we end up with 86.
Grab the next digit (9) from the dividend, add it to 86, then carry on: 869 / 87

Advancing to step 3:
When dividing 869 by 87, we get 9 with a remainder of 86.
Put 9 as the next digit of the answer. 
Result so far: 9.0
The remainder is 86 after subtracting 783 from 869.
Append the next digit (3) from the dividend to 86 and continue with: 863 / 87

Step 4:
87 goes into 863 9 times with a remainder of 80.
Use 9 as the next digit of our solution. 
Result so far: 99.0
Deduct 783 from 863 and we're left with 80.
Include the next digit (5) from the dividend after 80, then repeat: 805 / 87

Let's proceed to step 5:
87 goes into 805 9 times with a remainder of 22.
The next digit of our result is 9. 
Result so far: 999.0
Deduct 783 from 805 and we're left with 22.
Include the next digit (6) from the dividend after 22, then repeat: 226 / 87

Going ahead to step 6:
87 goes into 226 2 times with a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 9992.0
If we take 174 away from 226, we end up with 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Step 7:
When dividing 520 by 87, we get 5 with a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 9992.5
Deduct 435 from 520 and we're left with 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Going ahead to step 8:
87 goes into 850 9 times with a remainder of 67.
Put 9 as the next digit of the answer. 
Result so far: 9992.59
The remainder is 67 after subtracting 783 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Advancing to step 9:
The number 87 fits into 670 7 times, leaving a remainder of 61.
Record the quotient 7 as the next digit in the result. 
Result so far: 9992.597
If we subtract 609 from 670, we get 61.
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 10:
The number 87 fits into 610 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 9992.5977
If we take 609 away from 610, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The final outcome is 9992.5977, with a leftover of 1e-05.
