Let's divide 12575430 by 900
We're looking to find how many times 900 goes into 12575430.

Moving on to step 1:
The number 900 fits into 1 0 times, leaving a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 900

Let's proceed to step 2:
If we divide 12 by 900, we get 0 and a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 12 to get 12.
Fetch the next digit (5) from the dividend, attach it to 12 and continue: 125 / 900

Step 3:
If we divide 125 by 900, we get 0 and a remainder of 125.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 125, we end up with 125.
Fetch the next digit (7) from the dividend, attach it to 125 and continue: 1257 / 900

Moving on to step 4:
If we divide 1257 by 900, we get 1 and a remainder of 357.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 357 after subtracting 900 from 1257.
Include the next digit (5) from the dividend after 357, then repeat: 3575 / 900

Moving on to step 5:
900 goes into 3575 3 times with a remainder of 875.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 2700 from 3575 leaves us with 875.
Grab the next digit (4) from the dividend, add it to 875, then carry on: 8754 / 900

Step 6:
900 can be fit into 8754 9 times, resulting in a remainder of 654.
The next digit of our result is 9. 
Result so far: 139.0
If we subtract 8100 from 8754, we get 654.
Fetch the next digit (3) from the dividend, attach it to 654 and continue: 6543 / 900

Going ahead to step 7:
The number 900 fits into 6543 7 times, leaving a remainder of 243.
Put 7 as the next digit of the answer. 
Result so far: 1397.0
Subtracting 6300 from 6543 leaves us with 243.
Append the next digit (0) from the dividend to 243 and continue with: 2430 / 900

Going ahead to step 8:
2430 divided by 900 is 2 with a remainder of 630.
The next digit of our result is 2. 
Result so far: 13972.0
If we take 1800 away from 2430, we end up with 630.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6300, and continue the process.

Step 9:
The number 900 fits into 6300 7 times, leaving a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 13972.7
Subtracting 6300 from 6300 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.

Going ahead to step 10:
If we divide 0 by 900, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13972.7
If we subtract 0 from 0, we 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.

On to step 11:
900 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13972.7
The remainder is 0 after subtracting 0 from 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 result is 13972.7 with a remainder of 0.0.
