We're dividing 25793940 by 637 
We want to divide 25793940 by 637.

Going ahead to step 1:
The number 637 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 637

Moving on to step 2:
If we divide 25 by 637, we get 0 and a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Fetch the next digit (7) from the dividend, attach it to 25 and continue: 257 / 637

Advancing to step 3:
637 can be fit into 257 0 times, resulting in a remainder of 257.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 257 to get 257.
Append the next digit (9) from the dividend to 257 and continue with: 2579 / 637

On to step 4:
If we divide 2579 by 637, we get 4 and a remainder of 31.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 2548 from 2579, we get 31.
Grab the next digit (3) from the dividend, add it to 31, then carry on: 313 / 637

Step 5:
313 divided by 637 is 0 with a remainder of 313.
Put 0 as the next digit of the answer. 
Result so far: 40.0
If we subtract 0 from 313, we get 313.
Take the next digit (9) from the dividend and append it to 313, then repeat: 3139 / 637

Advancing to step 6:
637 can be fit into 3139 4 times, resulting in a remainder of 591.
Put 4 as the next digit of the answer. 
Result so far: 404.0
If we take 2548 away from 3139, we end up with 591.
Take the next digit (4) from the dividend and append it to 591, then repeat: 5914 / 637

Moving on to step 7:
637 can be fit into 5914 9 times, resulting in a remainder of 181.
The next digit of our result is 9. 
Result so far: 4049.0
Deduct 5733 from 5914 and we're left with 181.
Take the next digit (0) from the dividend and append it to 181, then repeat: 1810 / 637

On to step 8:
1810 divided by 637 is 2 with a remainder of 536.
The next digit of our result is 2. 
Result so far: 40492.0
The remainder is 536 after subtracting 1274 from 1810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5360, and continue the process.

Advancing to step 9:
5360 divided by 637 is 8 with a remainder of 264.
Put 8 as the next digit of the answer. 
Result so far: 40492.8
Subtracting 5096 from 5360 leaves us with 264.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2640, and continue the process.

Going ahead to step 10:
637 can be fit into 2640 4 times, resulting in a remainder of 92.
Write down 4 as next digit of the result. 
Result so far: 40492.84
If we take 2548 away from 2640, we end up 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.

Step 11:
637 can be fit into 920 1 times, resulting in a remainder of 283.
Put 1 as the next digit of the answer. 
Result so far: 40492.841
If we take 637 away from 920, we end up with 283.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2830, and continue the process.

Step 12:
637 can be fit into 2830 4 times, resulting in a remainder of 282.
Use 4 as the next digit of our solution. 
Result so far: 40492.8414
If we subtract 2548 from 2830, we get 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Moving on to step 13:
When dividing 2820 by 637, we get 4 with a remainder of 272.
Put 4 as the next digit of the answer. 
Result so far: 40492.84144
If we take 2548 away from 2820, we end up with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

The quotient of the division is 40492.84144, and the remainder is 0.000272.
