We look at the division of 18100681 by 900 
We want to divide 18100681 by 900.

Going ahead to step 1:
When dividing 1 by 900, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 900

Going ahead to step 2:
900 goes into 18 0 times with a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 18 leaves us with 18.
Take the next digit (1) from the dividend and append it to 18, then repeat: 181 / 900

Step 3:
The number 900 fits into 181 0 times, leaving a remainder of 181.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 181 after subtracting 0 from 181.
Include the next digit (0) from the dividend after 181, then repeat: 1810 / 900

On to step 4:
The number 900 fits into 1810 2 times, leaving a remainder of 10.
The next digit of our result is 2. 
Result so far: 2.0
If we subtract 1800 from 1810, we get 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 900

Advancing to step 5:
If we divide 100 by 900, we get 0 and a remainder of 100.
The next digit of our result is 0. 
Result so far: 20.0
If we take 0 away from 100, we end up with 100.
Append the next digit (6) from the dividend to 100 and continue with: 1006 / 900

Step 6:
When dividing 1006 by 900, we get 1 with a remainder of 106.
Put 1 as the next digit of the answer. 
Result so far: 201.0
Subtract 900 from 1006 to get 106.
Take the next digit (8) from the dividend and append it to 106, then repeat: 1068 / 900

Advancing to step 7:
900 goes into 1068 1 times with a remainder of 168.
Use 1 as the next digit of our solution. 
Result so far: 2011.0
Deduct 900 from 1068 and we're left with 168.
Include the next digit (1) from the dividend after 168, then repeat: 1681 / 900

Let's proceed to step 8:
900 can be fit into 1681 1 times, resulting in a remainder of 781.
The number 1 becomes the next digit in our result. 
Result so far: 20111.0
If we subtract 900 from 1681, we get 781.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7810, and continue the process.

Advancing to step 9:
900 goes into 7810 8 times with a remainder of 610.
Put 8 as the next digit of the answer. 
Result so far: 20111.8
Subtract 7200 from 7810 to get 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6100, and continue the process.

On to step 10:
900 goes into 6100 6 times with a remainder of 700.
Record the quotient 6 as the next digit in the result. 
Result so far: 20111.86
Deduct 5400 from 6100 and we're left with 700.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

Step 11:
When dividing 7000 by 900, we get 7 with a remainder of 700.
The next digit of our result is 7. 
Result so far: 20111.867
The remainder is 700 after subtracting 6300 from 7000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

On to step 12:
When dividing 7000 by 900, we get 7 with a remainder of 700.
Write down 7 as next digit of the result. 
Result so far: 20111.8677
The remainder is 700 after subtracting 6300 from 7000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7000, and continue the process.

The final result is 20111.8677 with a remainder of 0.007.
