Let's divide 25253642 by 604
We want to divide 25253642 by 604.

On to step 1:
604 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 604

Moving on to step 2:
When dividing 25 by 604, we get 0 with a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Include the next digit (2) from the dividend after 25, then repeat: 252 / 604

Moving on to step 3:
When dividing 252 by 604, we get 0 with a remainder of 252.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 252 to get 252.
Bring next digit (5) of the dividend behind the 252 and repeat the process: 2525 / 604

Moving on to step 4:
604 can be fit into 2525 4 times, resulting in a remainder of 109.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 2416 from 2525 leaves us with 109.
Fetch the next digit (3) from the dividend, attach it to 109 and continue: 1093 / 604

Advancing to step 5:
The number 604 fits into 1093 1 times, leaving a remainder of 489.
Use 1 as the next digit of our solution. 
Result so far: 41.0
The remainder is 489 after subtracting 604 from 1093.
Append the next digit (6) from the dividend to 489 and continue with: 4896 / 604

Going ahead to step 6:
4896 divided by 604 is 8 with a remainder of 64.
Write down 8 as next digit of the result. 
Result so far: 418.0
Subtract 4832 from 4896 to get 64.
Include the next digit (4) from the dividend after 64, then repeat: 644 / 604

Going ahead to step 7:
When dividing 644 by 604, we get 1 with a remainder of 40.
Write down 1 as next digit of the result. 
Result so far: 4181.0
If we take 604 away from 644, we end up with 40.
Take the next digit (2) from the dividend and append it to 40, then repeat: 402 / 604

Advancing to step 8:
604 can be fit into 402 0 times, resulting in a remainder of 402.
Put 0 as the next digit of the answer. 
Result so far: 41810.0
The remainder is 402 after subtracting 0 from 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Step 9:
604 can be fit into 4020 6 times, resulting in a remainder of 396.
Write down 6 as next digit of the result. 
Result so far: 41810.6
Subtract 3624 from 4020 to get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

Let's proceed to step 10:
604 can be fit into 3960 6 times, resulting in a remainder of 336.
Use 6 as the next digit of our solution. 
Result so far: 41810.66
Subtracting 3624 from 3960 leaves us with 336.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

The final outcome is 41810.66, with a leftover of 0.336.
