We look at the division of 25025641 by 400 
We want to divide 25025641 by 400.

Step 1:
2 divided by 400 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 400

Going ahead to step 2:
25 divided by 400 is 0 with a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Bring next digit (0) of the dividend behind the 25 and repeat the process: 250 / 400

Going ahead to step 3:
When dividing 250 by 400, we get 0 with a remainder of 250.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 250 and we're left with 250.
Take the next digit (2) from the dividend and append it to 250, then repeat: 2502 / 400

Going ahead to step 4:
2502 divided by 400 is 6 with a remainder of 102.
Write down 6 as next digit of the result. 
Result so far: 6.0
If we take 2400 away from 2502, we end up with 102.
Take the next digit (5) from the dividend and append it to 102, then repeat: 1025 / 400

On to step 5:
400 can be fit into 1025 2 times, resulting in a remainder of 225.
Put 2 as the next digit of the answer. 
Result so far: 62.0
Subtracting 800 from 1025 leaves us with 225.
Grab the next digit (6) from the dividend, add it to 225, then carry on: 2256 / 400

On to step 6:
When dividing 2256 by 400, we get 5 with a remainder of 256.
Record the quotient 5 as the next digit in the result. 
Result so far: 625.0
If we subtract 2000 from 2256, we get 256.
Include the next digit (4) from the dividend after 256, then repeat: 2564 / 400

Step 7:
If we divide 2564 by 400, we get 6 and a remainder of 164.
The number 6 becomes the next digit in our result. 
Result so far: 6256.0
Subtract 2400 from 2564 to get 164.
Bring next digit (1) of the dividend behind the 164 and repeat the process: 1641 / 400

Step 8:
400 goes into 1641 4 times with a remainder of 41.
The number 4 becomes the next digit in our result. 
Result so far: 62564.0
Subtracting 1600 from 1641 leaves us with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Let's proceed to step 9:
400 goes into 410 1 times with a remainder of 10.
The next digit of our result is 1. 
Result so far: 62564.1
Deduct 400 from 410 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
When dividing 100 by 400, we get 0 with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 62564.1
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Going ahead to step 11:
When dividing 1000 by 400, we get 2 with a remainder of 200.
The number 2 becomes the next digit in our result. 
Result so far: 62564.102
If we take 800 away from 1000, we end up with 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2000, and continue the process.

On to step 12:
2000 divided by 400 is 5 with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 62564.1025
If we take 2000 away from 2000, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 13:
400 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 62564.1025
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 14:
When dividing 0 by 400, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 62564.1025
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final result is 62564.1025 with a remainder of 0.0.
