We look at the division of 25717894 by 649 
We want to figure out the number of times 25717894 can be divided by 649.

Advancing to step 1:
649 can be fit into 2 0 times, resulting in a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (5) from the dividend, add it to 2, then carry on: 25 / 649

Advancing to step 2:
649 can be fit into 25 0 times, resulting in a remainder of 25.
Write down 0 as next digit of the 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 / 649

Step 3:
257 divided by 649 is 0 with a remainder of 257.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 257 after subtracting 0 from 257.
Fetch the next digit (1) from the dividend, attach it to 257 and continue: 2571 / 649

Going ahead to step 4:
The number 649 fits into 2571 3 times, leaving a remainder of 624.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we take 1947 away from 2571, we end up with 624.
Take the next digit (7) from the dividend and append it to 624, then repeat: 6247 / 649

Step 5:
When dividing 6247 by 649, we get 9 with a remainder of 406.
Write down 9 as next digit of the result. 
Result so far: 39.0
The remainder is 406 after subtracting 5841 from 6247.
Include the next digit (8) from the dividend after 406, then repeat: 4068 / 649

Moving on to step 6:
The number 649 fits into 4068 6 times, leaving a remainder of 174.
The next digit of our result is 6. 
Result so far: 396.0
If we subtract 3894 from 4068, we get 174.
Append the next digit (9) from the dividend to 174 and continue with: 1749 / 649

Advancing to step 7:
The number 649 fits into 1749 2 times, leaving a remainder of 451.
The next digit of our result is 2. 
Result so far: 3962.0
The remainder is 451 after subtracting 1298 from 1749.
Take the next digit (4) from the dividend and append it to 451, then repeat: 4514 / 649

Going ahead to step 8:
When dividing 4514 by 649, we get 6 with a remainder of 620.
Write down 6 as next digit of the result. 
Result so far: 39626.0
Subtract 3894 from 4514 to get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Going ahead to step 9:
649 can be fit into 6200 9 times, resulting in a remainder of 359.
Use 9 as the next digit of our solution. 
Result so far: 39626.9
Subtract 5841 from 6200 to get 359.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3590, and continue the process.

On to step 10:
3590 divided by 649 is 5 with a remainder of 345.
Put 5 as the next digit of the answer. 
Result so far: 39626.95
If we subtract 3245 from 3590, we get 345.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3450, and continue the process.

On to step 11:
649 goes into 3450 5 times with a remainder of 205.
Record the quotient 5 as the next digit in the result. 
Result so far: 39626.955
Subtract 3245 from 3450 to get 205.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

After the division, we end up with 39626.955 and a remainder of 0.0205.
