We look at the division of 12800223 by 900 
We want to divide 12800223 by 900.

On to step 1:
1 divided by 900 is 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 900

On to step 2:
When dividing 12 by 900, we get 0 with a remainder of 12.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Bring next digit (8) of the dividend behind the 12 and repeat the process: 128 / 900

Going ahead to step 3:
If we divide 128 by 900, we get 0 and a remainder of 128.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 128, we get 128.
Take the next digit (0) from the dividend and append it to 128, then repeat: 1280 / 900

Advancing to step 4:
1280 divided by 900 is 1 with a remainder of 380.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 900 away from 1280, we end up with 380.
Fetch the next digit (0) from the dividend, attach it to 380 and continue: 3800 / 900

On to step 5:
If we divide 3800 by 900, we get 4 and a remainder of 200.
Write down 4 as next digit of the result. 
Result so far: 14.0
The remainder is 200 after subtracting 3600 from 3800.
Append the next digit (2) from the dividend to 200 and continue with: 2002 / 900

Advancing to step 6:
900 goes into 2002 2 times with a remainder of 202.
Put 2 as the next digit of the answer. 
Result so far: 142.0
If we subtract 1800 from 2002, we get 202.
Fetch the next digit (2) from the dividend, attach it to 202 and continue: 2022 / 900

Step 7:
The number 900 fits into 2022 2 times, leaving a remainder of 222.
The number 2 becomes the next digit in our result. 
Result so far: 1422.0
The remainder is 222 after subtracting 1800 from 2022.
Append the next digit (3) from the dividend to 222 and continue with: 2223 / 900

Step 8:
If we divide 2223 by 900, we get 2 and a remainder of 423.
Put 2 as the next digit of the answer. 
Result so far: 14222.0
If we take 1800 away from 2223, we end up with 423.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4230, and continue the process.

Moving on to step 9:
The number 900 fits into 4230 4 times, leaving a remainder of 630.
The number 4 becomes the next digit in our result. 
Result so far: 14222.4
The remainder is 630 after subtracting 3600 from 4230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Moving on to step 10:
If we divide 6300 by 900, we get 7 and a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 14222.47
If we take 6300 away from 6300, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 11:
The number 900 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 14222.47
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 12:
When dividing 0 by 900, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 14222.47
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 14222.47, with a leftover of 0.0.
