We look at the division of 25272038 by 491 
The aim is to understand the frequency of 491 in 25272038.

Let's proceed to step 1:
If we divide 2 by 491, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in 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 / 491

Advancing to step 2:
If we divide 25 by 491, we get 0 and a remainder of 25.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 25, we get 25.
Append the next digit (2) from the dividend to 25 and continue with: 252 / 491

On to step 3:
252 divided by 491 is 0 with a remainder of 252.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 252 to get 252.
Take the next digit (7) from the dividend and append it to 252, then repeat: 2527 / 491

Going ahead to step 4:
491 can be fit into 2527 5 times, resulting in a remainder of 72.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Deduct 2455 from 2527 and we're left with 72.
Include the next digit (2) from the dividend after 72, then repeat: 722 / 491

Moving on to step 5:
491 can be fit into 722 1 times, resulting in a remainder of 231.
Put 1 as the next digit of the answer. 
Result so far: 51.0
If we subtract 491 from 722, we get 231.
Take the next digit (0) from the dividend and append it to 231, then repeat: 2310 / 491

On to step 6:
If we divide 2310 by 491, we get 4 and a remainder of 346.
The next digit of our result is 4. 
Result so far: 514.0
If we subtract 1964 from 2310, we get 346.
Grab the next digit (3) from the dividend, add it to 346, then carry on: 3463 / 491

Step 7:
491 can be fit into 3463 7 times, resulting in a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 5147.0
Deduct 3437 from 3463 and we're left with 26.
Fetch the next digit (8) from the dividend, attach it to 26 and continue: 268 / 491

Advancing to step 8:
If we divide 268 by 491, we get 0 and a remainder of 268.
Write down 0 as next digit of the result. 
Result so far: 51470.0
If we subtract 0 from 268, we get 268.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Going ahead to step 9:
491 goes into 2680 5 times with a remainder of 225.
Write down 5 as next digit of the result. 
Result so far: 51470.5
If we take 2455 away from 2680, we end up with 225.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2250, and continue the process.

On to step 10:
2250 divided by 491 is 4 with a remainder of 286.
The next digit of our result is 4. 
Result so far: 51470.54
The remainder is 286 after subtracting 1964 from 2250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2860, and continue the process.

Advancing to step 11:
When dividing 2860 by 491, we get 5 with a remainder of 405.
The next digit of our result is 5. 
Result so far: 51470.545
If we subtract 2455 from 2860, we get 405.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4050, and continue the process.

Let's proceed to step 12:
When dividing 4050 by 491, we get 8 with a remainder of 122.
The number 8 becomes the next digit in our result. 
Result so far: 51470.5458
Deduct 3928 from 4050 and we're left with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Let's proceed to step 13:
1220 divided by 491 is 2 with a remainder of 238.
The next digit of our result is 2. 
Result so far: 51470.54582
Subtracting 982 from 1220 leaves us with 238.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2380, and continue the process.

Moving on to step 14:
The number 491 fits into 2380 4 times, leaving a remainder of 416.
Write down 4 as next digit of the result. 
Result so far: 51470.545824
Subtract 1964 from 2380 to get 416.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4160, and continue the process.

On to step 15:
491 can be fit into 4160 8 times, resulting in a remainder of 232.
Put 8 as the next digit of the answer. 
Result so far: 51470.5458248
Subtracting 3928 from 4160 leaves us with 232.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2320, and continue the process.

Let's proceed to step 16:
491 goes into 2320 4 times with a remainder of 356.
Use 4 as the next digit of our solution. 
Result so far: 51470.54582484
The remainder is 356 after subtracting 1964 from 2320.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3560, and continue the process.

In conclusion, the division gives 51470.54582484 with a balance of 3.56e-07.
