12157294 ÷ 900 
Let's see how many times 900 fits into 12157294.

Let's proceed 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.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 900

Step 2:
900 goes into 12 0 times with a remainder of 12.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Include the next digit (1) from the dividend after 12, then repeat: 121 / 900

Moving on to step 3:
The number 900 fits into 121 0 times, leaving a remainder of 121.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 121 to get 121.
Fetch the next digit (5) from the dividend, attach it to 121 and continue: 1215 / 900

Moving on to step 4:
1215 divided by 900 is 1 with a remainder of 315.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 315 after subtracting 900 from 1215.
Take the next digit (7) from the dividend and append it to 315, then repeat: 3157 / 900

On to step 5:
When dividing 3157 by 900, we get 3 with a remainder of 457.
Put 3 as the next digit of the answer. 
Result so far: 13.0
The remainder is 457 after subtracting 2700 from 3157.
Bring next digit (2) of the dividend behind the 457 and repeat the process: 4572 / 900

Let's proceed to step 6:
900 goes into 4572 5 times with a remainder of 72.
Write down 5 as next digit of the result. 
Result so far: 135.0
The remainder is 72 after subtracting 4500 from 4572.
Fetch the next digit (9) from the dividend, attach it to 72 and continue: 729 / 900

Let's proceed to step 7:
The number 900 fits into 729 0 times, leaving a remainder of 729.
Use 0 as the next digit of our solution. 
Result so far: 1350.0
Deduct 0 from 729 and we're left with 729.
Grab the next digit (4) from the dividend, add it to 729, then carry on: 7294 / 900

Moving on to step 8:
When dividing 7294 by 900, we get 8 with a remainder of 94.
Put 8 as the next digit of the answer. 
Result so far: 13508.0
Subtract 7200 from 7294 to get 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 9:
The number 900 fits into 940 1 times, leaving a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 13508.1
The remainder is 40 after subtracting 900 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Going ahead to step 10:
900 goes into 400 0 times with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 13508.1
If we subtract 0 from 400, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Going ahead to step 11:
4000 divided by 900 is 4 with a remainder of 400.
Record the quotient 4 as the next digit in the result. 
Result so far: 13508.104
If we subtract 3600 from 4000, we get 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

Moving on to step 12:
The number 900 fits into 4000 4 times, leaving a remainder of 400.
Record the quotient 4 as the next digit in the result. 
Result so far: 13508.1044
Deduct 3600 from 4000 and we're left with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

The final outcome is 13508.1044, with a leftover of 0.004.
