We're dividing 87864110 by 900 
We want to divide 87864110 by 900.

Let's proceed to step 1:
8 divided by 900 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.
Append the next digit (7) from the dividend to 8 and continue with: 87 / 900

Step 2:
When dividing 87 by 900, we get 0 with a remainder of 87.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 87 and we're left with 87.
Bring next digit (8) of the dividend behind the 87 and repeat the process: 878 / 900

Step 3:
The number 900 fits into 878 0 times, leaving a remainder of 878.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 878, we end up with 878.
Take the next digit (6) from the dividend and append it to 878, then repeat: 8786 / 900

On to step 4:
900 can be fit into 8786 9 times, resulting in a remainder of 686.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Deduct 8100 from 8786 and we're left with 686.
Fetch the next digit (4) from the dividend, attach it to 686 and continue: 6864 / 900

Step 5:
The number 900 fits into 6864 7 times, leaving a remainder of 564.
Put 7 as the next digit of the answer. 
Result so far: 97.0
If we subtract 6300 from 6864, we get 564.
Append the next digit (1) from the dividend to 564 and continue with: 5641 / 900

Going ahead to step 6:
900 goes into 5641 6 times with a remainder of 241.
The next digit of our result is 6. 
Result so far: 976.0
Subtracting 5400 from 5641 leaves us with 241.
Grab the next digit (1) from the dividend, add it to 241, then carry on: 2411 / 900

On to step 7:
2411 divided by 900 is 2 with a remainder of 611.
The number 2 becomes the next digit in our result. 
Result so far: 9762.0
Subtracting 1800 from 2411 leaves us with 611.
Include the next digit (0) from the dividend after 611, then repeat: 6110 / 900

Let's proceed to step 8:
900 goes into 6110 6 times with a remainder of 710.
Record the quotient 6 as the next digit in the result. 
Result so far: 97626.0
If we take 5400 away from 6110, we end up with 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7100, and continue the process.

Moving on to step 9:
The number 900 fits into 7100 7 times, leaving a remainder of 800.
Put 7 as the next digit of the answer. 
Result so far: 97626.7
If we take 6300 away from 7100, we end up with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Going ahead to step 10:
When dividing 8000 by 900, we get 8 with a remainder of 800.
Write down 8 as next digit of the result. 
Result so far: 97626.78
If we take 7200 away from 8000, we end up with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

Going ahead to step 11:
8000 divided by 900 is 8 with a remainder of 800.
The next digit of our result is 8. 
Result so far: 97626.788
Subtracting 7200 from 8000 leaves us with 800.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8000, and continue the process.

After the division, we end up with 97626.788 and a remainder of 0.08.
