We look at the division of 25971554 by 487 
We're looking to find how many times 487 goes into 25971554.

Going ahead to step 1:
If we divide 2 by 487, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (5) from the dividend to 2 and continue with: 25 / 487

Moving on to step 2:
If we divide 25 by 487, we get 0 and a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Include the next digit (9) from the dividend after 25, then repeat: 259 / 487

Step 3:
The number 487 fits into 259 0 times, leaving a remainder of 259.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 259 leaves us with 259.
Bring next digit (7) of the dividend behind the 259 and repeat the process: 2597 / 487

Advancing to step 4:
The number 487 fits into 2597 5 times, leaving a remainder of 162.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 2435 from 2597 and we're left with 162.
Include the next digit (1) from the dividend after 162, then repeat: 1621 / 487

Moving on to step 5:
487 can be fit into 1621 3 times, resulting in a remainder of 160.
Write down 3 as next digit of the result. 
Result so far: 53.0
Subtract 1461 from 1621 to get 160.
Append the next digit (5) from the dividend to 160 and continue with: 1605 / 487

Step 6:
If we divide 1605 by 487, we get 3 and a remainder of 144.
Put 3 as the next digit of the answer. 
Result so far: 533.0
Subtract 1461 from 1605 to get 144.
Grab the next digit (5) from the dividend, add it to 144, then carry on: 1445 / 487

Going ahead to step 7:
If we divide 1445 by 487, we get 2 and a remainder of 471.
Write down 2 as next digit of the result. 
Result so far: 5332.0
The remainder is 471 after subtracting 974 from 1445.
Append the next digit (4) from the dividend to 471 and continue with: 4714 / 487

Step 8:
If we divide 4714 by 487, we get 9 and a remainder of 331.
Put 9 as the next digit of the answer. 
Result so far: 53329.0
If we subtract 4383 from 4714, we get 331.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3310, and continue the process.

Moving on to step 9:
487 goes into 3310 6 times with a remainder of 388.
Write down 6 as next digit of the result. 
Result so far: 53329.6
Subtracting 2922 from 3310 leaves us with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

Advancing to step 10:
If we divide 3880 by 487, we get 7 and a remainder of 471.
The number 7 becomes the next digit in our result. 
Result so far: 53329.67
Subtract 3409 from 3880 to get 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Moving on to step 11:
When dividing 4710 by 487, we get 9 with a remainder of 327.
Use 9 as the next digit of our solution. 
Result so far: 53329.679
If we subtract 4383 from 4710, we get 327.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3270, and continue the process.

Step 12:
487 goes into 3270 6 times with a remainder of 348.
Use 6 as the next digit of our solution. 
Result so far: 53329.6796
If we subtract 2922 from 3270, we get 348.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3480, and continue the process.

On to step 13:
The number 487 fits into 3480 7 times, leaving a remainder of 71.
Put 7 as the next digit of the answer. 
Result so far: 53329.67967
Deduct 3409 from 3480 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

On to step 14:
The number 487 fits into 710 1 times, leaving a remainder of 223.
Use 1 as the next digit of our solution. 
Result so far: 53329.679671
Subtract 487 from 710 to get 223.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2230, and continue the process.

Let's proceed to step 15:
The number 487 fits into 2230 4 times, leaving a remainder of 282.
Write down 4 as next digit of the result. 
Result so far: 53329.6796714
Deduct 1948 from 2230 and we're left with 282.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Let's proceed to step 16:
If we divide 2820 by 487, we get 5 and a remainder of 385.
Use 5 as the next digit of our solution. 
Result so far: 53329.67967145
If we subtract 2435 from 2820, we get 385.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3850, and continue the process.

The final result is 53329.67967145 with a remainder of 3.85e-07.
