25430245 ÷ 629 
We want to figure out the number of times 25430245 can be divided by 629.

Advancing to step 1:
2 divided by 629 is 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 629

Step 2:
When dividing 25 by 629, we get 0 with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Fetch the next digit (4) from the dividend, attach it to 25 and continue: 254 / 629

Moving on to step 3:
If we divide 254 by 629, we get 0 and a remainder of 254.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 254 after subtracting 0 from 254.
Grab the next digit (3) from the dividend, add it to 254, then carry on: 2543 / 629

Moving on to step 4:
629 goes into 2543 4 times with a remainder of 27.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtract 2516 from 2543 to get 27.
Append the next digit (0) from the dividend to 27 and continue with: 270 / 629

Going ahead to step 5:
629 goes into 270 0 times with a remainder of 270.
Write down 0 as next digit of the result. 
Result so far: 40.0
Deduct 0 from 270 and we're left with 270.
Take the next digit (2) from the dividend and append it to 270, then repeat: 2702 / 629

Advancing to step 6:
2702 divided by 629 is 4 with a remainder of 186.
Write down 4 as next digit of the result. 
Result so far: 404.0
If we take 2516 away from 2702, we end up with 186.
Bring next digit (4) of the dividend behind the 186 and repeat the process: 1864 / 629

Let's proceed to step 7:
1864 divided by 629 is 2 with a remainder of 606.
Write down 2 as next digit of the result. 
Result so far: 4042.0
Subtracting 1258 from 1864 leaves us with 606.
Include the next digit (5) from the dividend after 606, then repeat: 6065 / 629

Going ahead to step 8:
The number 629 fits into 6065 9 times, leaving a remainder of 404.
The number 9 becomes the next digit in our result. 
Result so far: 40429.0
The remainder is 404 after subtracting 5661 from 6065.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4040, and continue the process.

Advancing to step 9:
4040 divided by 629 is 6 with a remainder of 266.
Record the quotient 6 as the next digit in the result. 
Result so far: 40429.6
If we subtract 3774 from 4040, we get 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Going ahead to step 10:
629 goes into 2660 4 times with a remainder of 144.
The next digit of our result is 4. 
Result so far: 40429.64
Deduct 2516 from 2660 and we're left with 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 11:
When dividing 1440 by 629, we get 2 with a remainder of 182.
Write down 2 as next digit of the result. 
Result so far: 40429.642
If we subtract 1258 from 1440, we get 182.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1820, and continue the process.

On to step 12:
The number 629 fits into 1820 2 times, leaving a remainder of 562.
Use 2 as the next digit of our solution. 
Result so far: 40429.6422
Subtract 1258 from 1820 to get 562.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5620, and continue the process.

In conclusion, the division gives 40429.6422 with a balance of 0.00562.
