18399809 divided by 900 
We want to divide 18399809 by 900.

Let's proceed to step 1:
900 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 900

Step 2:
900 goes into 18 0 times with a remainder of 18.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 18, we end up with 18.
Fetch the next digit (3) from the dividend, attach it to 18 and continue: 183 / 900

Advancing to step 3:
When dividing 183 by 900, we get 0 with a remainder of 183.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 183 leaves us with 183.
Grab the next digit (9) from the dividend, add it to 183, then carry on: 1839 / 900

Going ahead to step 4:
The number 900 fits into 1839 2 times, leaving a remainder of 39.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 1800 away from 1839, we end up with 39.
Fetch the next digit (9) from the dividend, attach it to 39 and continue: 399 / 900

Going ahead to step 5:
399 divided by 900 is 0 with a remainder of 399.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
Deduct 0 from 399 and we're left with 399.
Grab the next digit (8) from the dividend, add it to 399, then carry on: 3998 / 900

On to step 6:
When dividing 3998 by 900, we get 4 with a remainder of 398.
The next digit of our result is 4. 
Result so far: 204.0
The remainder is 398 after subtracting 3600 from 3998.
Fetch the next digit (0) from the dividend, attach it to 398 and continue: 3980 / 900

Advancing to step 7:
900 can be fit into 3980 4 times, resulting in a remainder of 380.
The next digit of our result is 4. 
Result so far: 2044.0
Deduct 3600 from 3980 and we're left with 380.
Include the next digit (9) from the dividend after 380, then repeat: 3809 / 900

Going ahead to step 8:
The number 900 fits into 3809 4 times, leaving a remainder of 209.
The number 4 becomes the next digit in our result. 
Result so far: 20444.0
If we subtract 3600 from 3809, we get 209.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2090, and continue the process.

Step 9:
When dividing 2090 by 900, we get 2 with a remainder of 290.
The next digit of our result is 2. 
Result so far: 20444.2
If we take 1800 away from 2090, we end up with 290.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2900, and continue the process.

Let's proceed to step 10:
900 goes into 2900 3 times with a remainder of 200.
The next digit of our result is 3. 
Result so far: 20444.23
If we subtract 2700 from 2900, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Advancing to step 11:
900 can be fit into 2000 2 times, resulting in a remainder of 200.
Use 2 as the next digit of our solution. 
Result so far: 20444.232
If we take 1800 away from 2000, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Going ahead to step 12:
900 goes into 2000 2 times with a remainder of 200.
The next digit of our result is 2. 
Result so far: 20444.2322
The remainder is 200 after subtracting 1800 from 2000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

Our division results in 20444.2322 with a remaining 0.002.
