We're dividing 12252544 by 804 
Let's see how many times 804 fits into 12252544.

Let's proceed to step 1:
804 goes into 1 0 times with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 804

On to step 2:
When dividing 12 by 804, we get 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 12 after subtracting 0 from 12.
Append the next digit (2) from the dividend to 12 and continue with: 122 / 804

Moving on to step 3:
122 divided by 804 is 0 with a remainder of 122.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 122, we get 122.
Append the next digit (5) from the dividend to 122 and continue with: 1225 / 804

Let's proceed to step 4:
When dividing 1225 by 804, we get 1 with a remainder of 421.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 804 from 1225 to get 421.
Include the next digit (2) from the dividend after 421, then repeat: 4212 / 804

Let's proceed to step 5:
804 goes into 4212 5 times with a remainder of 192.
The next digit of our result is 5. 
Result so far: 15.0
The remainder is 192 after subtracting 4020 from 4212.
Grab the next digit (5) from the dividend, add it to 192, then carry on: 1925 / 804

Let's proceed to step 6:
1925 divided by 804 is 2 with a remainder of 317.
The number 2 becomes the next digit in our result. 
Result so far: 152.0
If we take 1608 away from 1925, we end up with 317.
Include the next digit (4) from the dividend after 317, then repeat: 3174 / 804

On to step 7:
3174 divided by 804 is 3 with a remainder of 762.
Record the quotient 3 as the next digit in the result. 
Result so far: 1523.0
Subtract 2412 from 3174 to get 762.
Include the next digit (4) from the dividend after 762, then repeat: 7624 / 804

Let's proceed to step 8:
The number 804 fits into 7624 9 times, leaving a remainder of 388.
Use 9 as the next digit of our solution. 
Result so far: 15239.0
If we subtract 7236 from 7624, we get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Let's proceed to step 9:
If we divide 3880 by 804, we get 4 and a remainder of 664.
Write down 4 as next digit of the result. 
Result so far: 15239.4
Deduct 3216 from 3880 and we're left with 664.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6640, and continue the process.

Moving on to step 10:
The number 804 fits into 6640 8 times, leaving a remainder of 208.
The next digit of our result is 8. 
Result so far: 15239.48
Subtracting 6432 from 6640 leaves us with 208.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2080, and continue the process.

Let's proceed to step 11:
The number 804 fits into 2080 2 times, leaving a remainder of 472.
The number 2 becomes the next digit in our result. 
Result so far: 15239.482
Subtracting 1608 from 2080 leaves us with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Going ahead to step 12:
The number 804 fits into 4720 5 times, leaving a remainder of 700.
Record the quotient 5 as the next digit in the result. 
Result so far: 15239.4825
Subtract 4020 from 4720 to get 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 13:
If we divide 7000 by 804, we get 8 and a remainder of 568.
Put 8 as the next digit of the answer. 
Result so far: 15239.48258
Subtracting 6432 from 7000 leaves us with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Moving on to step 14:
804 can be fit into 5680 7 times, resulting in a remainder of 52.
The next digit of our result is 7. 
Result so far: 15239.482587
Subtract 5628 from 5680 to get 52.
Since there are no more digits in the dividend, we add a zero to the remainder making it 520, and continue the process.

Moving on to step 15:
The number 804 fits into 520 0 times, leaving a remainder of 520.
The number 0 becomes the next digit in our result. 
Result so far: 15239.482587
The remainder is 520 after subtracting 0 from 520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5200, and continue the process.

Step 16:
804 can be fit into 5200 6 times, resulting in a remainder of 376.
Put 6 as the next digit of the answer. 
Result so far: 15239.48258706
Deduct 4824 from 5200 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

In conclusion, the division gives 15239.48258706 with a balance of 3.76e-07.
