25732960 ÷ 638 
We want to figure out the number of times 25732960 can be divided by 638.

Let's proceed to step 1:
638 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 638

Step 2:
The number 638 fits into 25 0 times, leaving a remainder of 25.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Bring next digit (7) of the dividend behind the 25 and repeat the process: 257 / 638

Advancing to step 3:
If we divide 257 by 638, we get 0 and a remainder of 257.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 257 to get 257.
Bring next digit (3) of the dividend behind the 257 and repeat the process: 2573 / 638

Advancing to step 4:
638 can be fit into 2573 4 times, resulting in a remainder of 21.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 2552 from 2573 leaves us with 21.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 638

On to step 5:
If we divide 212 by 638, we get 0 and a remainder of 212.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
If we subtract 0 from 212, we get 212.
Take the next digit (9) from the dividend and append it to 212, then repeat: 2129 / 638

Step 6:
638 can be fit into 2129 3 times, resulting in a remainder of 215.
The number 3 becomes the next digit in our result. 
Result so far: 403.0
If we subtract 1914 from 2129, we get 215.
Take the next digit (6) from the dividend and append it to 215, then repeat: 2156 / 638

On to step 7:
When dividing 2156 by 638, we get 3 with a remainder of 242.
Use 3 as the next digit of our solution. 
Result so far: 4033.0
Subtract 1914 from 2156 to get 242.
Include the next digit (0) from the dividend after 242, then repeat: 2420 / 638

Going ahead to step 8:
638 goes into 2420 3 times with a remainder of 506.
The next digit of our result is 3. 
Result so far: 40333.0
Subtracting 1914 from 2420 leaves us with 506.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5060, and continue the process.

Step 9:
The number 638 fits into 5060 7 times, leaving a remainder of 594.
The number 7 becomes the next digit in our result. 
Result so far: 40333.7
Subtracting 4466 from 5060 leaves us with 594.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5940, and continue the process.

On to step 10:
638 goes into 5940 9 times with a remainder of 198.
Use 9 as the next digit of our solution. 
Result so far: 40333.79
Subtracting 5742 from 5940 leaves us with 198.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1980, and continue the process.

Advancing to step 11:
If we divide 1980 by 638, we get 3 and a remainder of 66.
The next digit of our result is 3. 
Result so far: 40333.793
Subtract 1914 from 1980 to get 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Let's proceed to step 12:
638 can be fit into 660 1 times, resulting in a remainder of 22.
The number 1 becomes the next digit in our result. 
Result so far: 40333.7931
If we subtract 638 from 660, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 13:
638 can be fit into 220 0 times, resulting in a remainder of 220.
The next digit of our result is 0. 
Result so far: 40333.7931
The remainder is 220 after subtracting 0 from 220.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2200, and continue the process.

Let's proceed to step 14:
638 can be fit into 2200 3 times, resulting in a remainder of 286.
The number 3 becomes the next digit in our result. 
Result so far: 40333.793103
Deduct 1914 from 2200 and we're left with 286.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

On to step 15:
2860 divided by 638 is 4 with a remainder of 308.
Write down 4 as next digit of the result. 
Result so far: 40333.7931034
If we subtract 2552 from 2860, we get 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 16:
3080 divided by 638 is 4 with a remainder of 528.
Put 4 as the next digit of the answer. 
Result so far: 40333.79310344
The remainder is 528 after subtracting 2552 from 3080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5280, and continue the process.

After the division, we end up with 40333.79310344 and a remainder of 5.28e-07.
