25904201 divided by 204 
Our goal is to divide 25904201 by 204.

On to step 1:
204 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 204

Step 2:
The number 204 fits into 25 0 times, leaving a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Take the next digit (9) from the dividend and append it to 25, then repeat: 259 / 204

Advancing to step 3:
259 divided by 204 is 1 with a remainder of 55.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 204 from 259 and we're left with 55.
Append the next digit (0) from the dividend to 55 and continue with: 550 / 204

Step 4:
The number 204 fits into 550 2 times, leaving a remainder of 142.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 408 from 550 leaves us with 142.
Grab the next digit (4) from the dividend, add it to 142, then carry on: 1424 / 204

Going ahead to step 5:
204 goes into 1424 6 times with a remainder of 200.
Record the quotient 6 as the next digit in the result. 
Result so far: 126.0
If we subtract 1224 from 1424, we get 200.
Include the next digit (2) from the dividend after 200, then repeat: 2002 / 204

Advancing to step 6:
The number 204 fits into 2002 9 times, leaving a remainder of 166.
Put 9 as the next digit of the answer. 
Result so far: 1269.0
If we subtract 1836 from 2002, we get 166.
Append the next digit (0) from the dividend to 166 and continue with: 1660 / 204

On to step 7:
When dividing 1660 by 204, we get 8 with a remainder of 28.
Put 8 as the next digit of the answer. 
Result so far: 12698.0
If we subtract 1632 from 1660, we get 28.
Take the next digit (1) from the dividend and append it to 28, then repeat: 281 / 204

Advancing to step 8:
If we divide 281 by 204, we get 1 and a remainder of 77.
Put 1 as the next digit of the answer. 
Result so far: 126981.0
The remainder is 77 after subtracting 204 from 281.
Since there are no more digits in the dividend, we add a zero to the remainder making it 770, and continue the process.

On to step 9:
When dividing 770 by 204, we get 3 with a remainder of 158.
Write down 3 as next digit of the result. 
Result so far: 126981.3
If we subtract 612 from 770, we get 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

On to step 10:
When dividing 1580 by 204, we get 7 with a remainder of 152.
The next digit of our result is 7. 
Result so far: 126981.37
If we subtract 1428 from 1580, we get 152.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1520, and continue the process.

Step 11:
When dividing 1520 by 204, we get 7 with a remainder of 92.
Put 7 as the next digit of the answer. 
Result so far: 126981.377
The remainder is 92 after subtracting 1428 from 1520.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

The final result is 126981.377 with a remainder of 0.0092.
