We look at the division of 25403295 by 315 
We want to figure out the number of times 25403295 can be divided by 315.

Step 1:
If we divide 2 by 315, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 315

Moving on to step 2:
When dividing 25 by 315, we get 0 with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Append the next digit (4) from the dividend to 25 and continue with: 254 / 315

Advancing to step 3:
When dividing 254 by 315, we get 0 with a remainder of 254.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 254 and we're left with 254.
Include the next digit (0) from the dividend after 254, then repeat: 2540 / 315

Step 4:
When dividing 2540 by 315, we get 8 with a remainder of 20.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 2520 from 2540 leaves us with 20.
Append the next digit (3) from the dividend to 20 and continue with: 203 / 315

Going ahead to step 5:
The number 315 fits into 203 0 times, leaving a remainder of 203.
The number 0 becomes the next digit in our result. 
Result so far: 80.0
Subtracting 0 from 203 leaves us with 203.
Include the next digit (2) from the dividend after 203, then repeat: 2032 / 315

Advancing to step 6:
2032 divided by 315 is 6 with a remainder of 142.
Put 6 as the next digit of the answer. 
Result so far: 806.0
Deduct 1890 from 2032 and we're left with 142.
Bring next digit (9) of the dividend behind the 142 and repeat the process: 1429 / 315

Moving on to step 7:
315 goes into 1429 4 times with a remainder of 169.
Write down 4 as next digit of the result. 
Result so far: 8064.0
Subtract 1260 from 1429 to get 169.
Append the next digit (5) from the dividend to 169 and continue with: 1695 / 315

Moving on to step 8:
315 can be fit into 1695 5 times, resulting in a remainder of 120.
Record the quotient 5 as the next digit in the result. 
Result so far: 80645.0
Subtract 1575 from 1695 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 9:
The number 315 fits into 1200 3 times, leaving a remainder of 255.
Use 3 as the next digit of our solution. 
Result so far: 80645.3
Subtract 945 from 1200 to get 255.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

On to step 10:
315 goes into 2550 8 times with a remainder of 30.
Record the quotient 8 as the next digit in the result. 
Result so far: 80645.38
Deduct 2520 from 2550 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 11:
315 can be fit into 300 0 times, resulting in a remainder of 300.
Record the quotient 0 as the next digit in the result. 
Result so far: 80645.38
Subtract 0 from 300 to get 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Let's proceed to step 12:
The number 315 fits into 3000 9 times, leaving a remainder of 165.
Put 9 as the next digit of the answer. 
Result so far: 80645.3809
The remainder is 165 after subtracting 2835 from 3000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1650, and continue the process.

Step 13:
1650 divided by 315 is 5 with a remainder of 75.
The next digit of our result is 5. 
Result so far: 80645.38095
Subtract 1575 from 1650 to get 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Advancing to step 14:
315 goes into 750 2 times with a remainder of 120.
The number 2 becomes the next digit in our result. 
Result so far: 80645.380952
The remainder is 120 after subtracting 630 from 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 15:
1200 divided by 315 is 3 with a remainder of 255.
The number 3 becomes the next digit in our result. 
Result so far: 80645.3809523
The remainder is 255 after subtracting 945 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2550, and continue the process.

Step 16:
If we divide 2550 by 315, we get 8 and a remainder of 30.
The next digit of our result is 8. 
Result so far: 80645.38095238
If we subtract 2520 from 2550, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

In conclusion, the division gives 80645.38095238 with a balance of 3e-08.
