We're dividing 25919209 by 400 
Our goal is to divide 25919209 by 400.

Step 1:
The number 400 fits into 2 0 times, leaving a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 400

Advancing to step 2:
If we divide 25 by 400, we get 0 and a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 25, we end up with 25.
Bring next digit (9) of the dividend behind the 25 and repeat the process: 259 / 400

On to step 3:
400 goes into 259 0 times with a remainder of 259.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 259 and we're left with 259.
Fetch the next digit (1) from the dividend, attach it to 259 and continue: 2591 / 400

Moving on to step 4:
The number 400 fits into 2591 6 times, leaving a remainder of 191.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
The remainder is 191 after subtracting 2400 from 2591.
Bring next digit (9) of the dividend behind the 191 and repeat the process: 1919 / 400

Advancing to step 5:
When dividing 1919 by 400, we get 4 with a remainder of 319.
Use 4 as the next digit of our solution. 
Result so far: 64.0
Subtracting 1600 from 1919 leaves us with 319.
Grab the next digit (2) from the dividend, add it to 319, then carry on: 3192 / 400

Moving on to step 6:
3192 divided by 400 is 7 with a remainder of 392.
Put 7 as the next digit of the answer. 
Result so far: 647.0
The remainder is 392 after subtracting 2800 from 3192.
Bring next digit (0) of the dividend behind the 392 and repeat the process: 3920 / 400

On to step 7:
If we divide 3920 by 400, we get 9 and a remainder of 320.
The next digit of our result is 9. 
Result so far: 6479.0
Deduct 3600 from 3920 and we're left with 320.
Grab the next digit (9) from the dividend, add it to 320, then carry on: 3209 / 400

Advancing to step 8:
400 can be fit into 3209 8 times, resulting in a remainder of 9.
The next digit of our result is 8. 
Result so far: 64798.0
If we subtract 3200 from 3209, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 9:
If we divide 90 by 400, we get 0 and a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 64798.0
The remainder is 90 after subtracting 0 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Let's proceed to step 10:
400 can be fit into 900 2 times, resulting in a remainder of 100.
Record the quotient 2 as the next digit in the result. 
Result so far: 64798.02
Subtract 800 from 900 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 11:
1000 divided by 400 is 2 with a remainder of 200.
Record the quotient 2 as the next digit in the result. 
Result so far: 64798.022
If we subtract 800 from 1000, we get 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

In conclusion, the division gives 64798.022 with a balance of 0.02.
