25011475 divided by 406 
Our goal is to divide 25011475 by 406.

Let's proceed to step 1:
If we divide 2 by 406, we get 0 and 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.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 406

Let's proceed to step 2:
If we divide 25 by 406, we get 0 and a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Bring next digit (0) of the dividend behind the 25 and repeat the process: 250 / 406

On to step 3:
406 can be fit into 250 0 times, resulting in a remainder of 250.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 250 after subtracting 0 from 250.
Append the next digit (1) from the dividend to 250 and continue with: 2501 / 406

Going ahead to step 4:
2501 divided by 406 is 6 with a remainder of 65.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 2436 from 2501 and we're left with 65.
Bring next digit (1) of the dividend behind the 65 and repeat the process: 651 / 406

Going ahead to step 5:
406 can be fit into 651 1 times, resulting in a remainder of 245.
Use 1 as the next digit of our solution. 
Result so far: 61.0
Subtract 406 from 651 to get 245.
Append the next digit (4) from the dividend to 245 and continue with: 2454 / 406

Moving on to step 6:
406 can be fit into 2454 6 times, resulting in a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 616.0
If we subtract 2436 from 2454, we get 18.
Fetch the next digit (7) from the dividend, attach it to 18 and continue: 187 / 406

Let's proceed to step 7:
406 goes into 187 0 times with a remainder of 187.
The number 0 becomes the next digit in our result. 
Result so far: 6160.0
Deduct 0 from 187 and we're left with 187.
Fetch the next digit (5) from the dividend, attach it to 187 and continue: 1875 / 406

Step 8:
When dividing 1875 by 406, we get 4 with a remainder of 251.
Put 4 as the next digit of the answer. 
Result so far: 61604.0
Subtract 1624 from 1875 to get 251.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2510, and continue the process.

Let's proceed to step 9:
The number 406 fits into 2510 6 times, leaving a remainder of 74.
The next digit of our result is 6. 
Result so far: 61604.6
Subtract 2436 from 2510 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

On to step 10:
406 goes into 740 1 times with a remainder of 334.
The number 1 becomes the next digit in our result. 
Result so far: 61604.61
Subtract 406 from 740 to get 334.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3340, and continue the process.

Step 11:
406 can be fit into 3340 8 times, resulting in a remainder of 92.
Put 8 as the next digit of the answer. 
Result so far: 61604.618
Subtracting 3248 from 3340 leaves us with 92.
Since there are no more digits in the dividend, we add a zero to the remainder making it 920, and continue the process.

Let's proceed to step 12:
If we divide 920 by 406, we get 2 and a remainder of 108.
Write down 2 as next digit of the result. 
Result so far: 61604.6182
Subtracting 812 from 920 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Going ahead to step 13:
If we divide 1080 by 406, we get 2 and a remainder of 268.
Put 2 as the next digit of the answer. 
Result so far: 61604.61822
If we take 812 away from 1080, we end up with 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

The final outcome is 61604.61822, with a leftover of 0.000268.
