We're dividing 25397226 by 548 
The aim is to understand the frequency of 548 in 25397226.

Going ahead to step 1:
The number 548 fits into 2 0 times, leaving 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 / 548

Advancing to step 2:
If we divide 25 by 548, we get 0 and 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.
Include the next digit (3) from the dividend after 25, then repeat: 253 / 548

Going ahead to step 3:
548 can be fit into 253 0 times, resulting in a remainder of 253.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 253 leaves us with 253.
Take the next digit (9) from the dividend and append it to 253, then repeat: 2539 / 548

On to step 4:
When dividing 2539 by 548, we get 4 with a remainder of 347.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we subtract 2192 from 2539, we get 347.
Bring next digit (7) of the dividend behind the 347 and repeat the process: 3477 / 548

Step 5:
If we divide 3477 by 548, we get 6 and a remainder of 189.
The next digit of our result is 6. 
Result so far: 46.0
If we subtract 3288 from 3477, we get 189.
Grab the next digit (2) from the dividend, add it to 189, then carry on: 1892 / 548

Moving on to step 6:
1892 divided by 548 is 3 with a remainder of 248.
Write down 3 as next digit of the result. 
Result so far: 463.0
Deduct 1644 from 1892 and we're left with 248.
Fetch the next digit (2) from the dividend, attach it to 248 and continue: 2482 / 548

Going ahead to step 7:
548 can be fit into 2482 4 times, resulting in a remainder of 290.
Put 4 as the next digit of the answer. 
Result so far: 4634.0
The remainder is 290 after subtracting 2192 from 2482.
Fetch the next digit (6) from the dividend, attach it to 290 and continue: 2906 / 548

Step 8:
548 can be fit into 2906 5 times, resulting in a remainder of 166.
The number 5 becomes the next digit in our result. 
Result so far: 46345.0
The remainder is 166 after subtracting 2740 from 2906.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1660, and continue the process.

Going ahead to step 9:
548 can be fit into 1660 3 times, resulting in a remainder of 16.
Write down 3 as next digit of the result. 
Result so far: 46345.3
The remainder is 16 after subtracting 1644 from 1660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
If we divide 160 by 548, we get 0 and a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 46345.3
Deduct 0 from 160 and we're left with 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Advancing to step 11:
If we divide 1600 by 548, we get 2 and a remainder of 504.
Put 2 as the next digit of the answer. 
Result so far: 46345.302
The remainder is 504 after subtracting 1096 from 1600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Let's proceed to step 12:
If we divide 5040 by 548, we get 9 and a remainder of 108.
Record the quotient 9 as the next digit in the result. 
Result so far: 46345.3029
Subtracting 4932 from 5040 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Step 13:
When dividing 1080 by 548, we get 1 with a remainder of 532.
Write down 1 as next digit of the result. 
Result so far: 46345.30291
If we take 548 away from 1080, we end up with 532.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5320, and continue the process.

Going ahead to step 14:
The number 548 fits into 5320 9 times, leaving a remainder of 388.
The number 9 becomes the next digit in our result. 
Result so far: 46345.302919
Subtract 4932 from 5320 to get 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 15:
If we divide 3880 by 548, we get 7 and a remainder of 44.
The next digit of our result is 7. 
Result so far: 46345.3029197
If we take 3836 away from 3880, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Let's proceed to step 16:
548 can be fit into 440 0 times, resulting in a remainder of 440.
Record the quotient 0 as the next digit in the result. 
Result so far: 46345.3029197
Subtracting 0 from 440 leaves us with 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

The final outcome is 46345.3029197, with a leftover of 4.4e-07.
