25677144 ÷ 451 
We want to figure out the number of times 25677144 can be divided by 451.

On to step 1:
The number 451 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 451

Advancing to step 2:
The number 451 fits into 25 0 times, leaving a remainder of 25.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 25 leaves us with 25.
Fetch the next digit (6) from the dividend, attach it to 25 and continue: 256 / 451

Let's proceed to step 3:
The number 451 fits into 256 0 times, leaving a remainder of 256.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 256 and we're left with 256.
Grab the next digit (7) from the dividend, add it to 256, then carry on: 2567 / 451

Going ahead to step 4:
2567 divided by 451 is 5 with a remainder of 312.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 2255 from 2567 leaves us with 312.
Grab the next digit (7) from the dividend, add it to 312, then carry on: 3127 / 451

Let's proceed to step 5:
451 goes into 3127 6 times with a remainder of 421.
Write down 6 as next digit of the result. 
Result so far: 56.0
The remainder is 421 after subtracting 2706 from 3127.
Take the next digit (1) from the dividend and append it to 421, then repeat: 4211 / 451

Going ahead to step 6:
The number 451 fits into 4211 9 times, leaving a remainder of 152.
Put 9 as the next digit of the answer. 
Result so far: 569.0
If we subtract 4059 from 4211, we get 152.
Include the next digit (4) from the dividend after 152, then repeat: 1524 / 451

On to step 7:
451 can be fit into 1524 3 times, resulting in a remainder of 171.
The number 3 becomes the next digit in our result. 
Result so far: 5693.0
Subtract 1353 from 1524 to get 171.
Include the next digit (4) from the dividend after 171, then repeat: 1714 / 451

Advancing to step 8:
The number 451 fits into 1714 3 times, leaving a remainder of 361.
The number 3 becomes the next digit in our result. 
Result so far: 56933.0
Subtracting 1353 from 1714 leaves us with 361.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3610, and continue the process.

Step 9:
451 can be fit into 3610 8 times, resulting in a remainder of 2.
The next digit of our result is 8. 
Result so far: 56933.8
Subtracting 3608 from 3610 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 10:
451 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 56933.8
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 11:
451 can be fit into 200 0 times, resulting in a remainder of 200.
Put 0 as the next digit of the answer. 
Result so far: 56933.8
If we take 0 away from 200, 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.

The quotient of the division is 56933.8, and the remainder is 0.02.
