25493179 ÷ 400 
Let's see how many times 400 fits into 25493179.

Going ahead to step 1:
The number 400 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 400

Let's proceed to step 2:
400 goes into 25 0 times with a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 25 and we're left with 25.
Take the next digit (4) from the dividend and append it to 25, then repeat: 254 / 400

Moving on to step 3:
When dividing 254 by 400, we get 0 with a remainder of 254.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 254 to get 254.
Include the next digit (9) from the dividend after 254, then repeat: 2549 / 400

Moving on to step 4:
400 goes into 2549 6 times with a remainder of 149.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 2400 from 2549, we get 149.
Take the next digit (3) from the dividend and append it to 149, then repeat: 1493 / 400

On to step 5:
The number 400 fits into 1493 3 times, leaving a remainder of 293.
Put 3 as the next digit of the answer. 
Result so far: 63.0
If we take 1200 away from 1493, we end up with 293.
Grab the next digit (1) from the dividend, add it to 293, then carry on: 2931 / 400

Let's proceed to step 6:
The number 400 fits into 2931 7 times, leaving a remainder of 131.
The number 7 becomes the next digit in our result. 
Result so far: 637.0
If we take 2800 away from 2931, we end up with 131.
Take the next digit (7) from the dividend and append it to 131, then repeat: 1317 / 400

Moving on to step 7:
400 can be fit into 1317 3 times, resulting in a remainder of 117.
Write down 3 as next digit of the result. 
Result so far: 6373.0
Deduct 1200 from 1317 and we're left with 117.
Fetch the next digit (9) from the dividend, attach it to 117 and continue: 1179 / 400

Moving on to step 8:
400 goes into 1179 2 times with a remainder of 379.
Write down 2 as next digit of the result. 
Result so far: 63732.0
If we take 800 away from 1179, we end up with 379.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3790, and continue the process.

Advancing to step 9:
3790 divided by 400 is 9 with a remainder of 190.
Put 9 as the next digit of the answer. 
Result so far: 63732.9
The remainder is 190 after subtracting 3600 from 3790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

On to step 10:
1900 divided by 400 is 4 with a remainder of 300.
Record the quotient 4 as the next digit in the result. 
Result so far: 63732.94
The remainder is 300 after subtracting 1600 from 1900.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3000, and continue the process.

Step 11:
400 can be fit into 3000 7 times, resulting in a remainder of 200.
Put 7 as the next digit of the answer. 
Result so far: 63732.947
Subtract 2800 from 3000 to 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.

Going ahead to step 12:
400 goes into 2000 5 times with a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 63732.9475
Deduct 2000 from 2000 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.

Let's proceed to step 13:
If we divide 0 by 400, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 63732.9475
The remainder is 0 after subtracting 0 from 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 14:
If we divide 0 by 400, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 63732.9475
If we subtract 0 from 0, we 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.

Our division results in 63732.9475 with a remaining 0.0.
