We're dividing 15197533 by 404 
The aim is to understand the frequency of 404 in 15197533.

Moving on to step 1:
If we divide 1 by 404, we get 0 and a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 404

Going ahead to step 2:
404 goes into 15 0 times with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 15, we end up with 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 404

On to step 3:
If we divide 151 by 404, we get 0 and a remainder of 151.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 151 and we're left with 151.
Take the next digit (9) from the dividend and append it to 151, then repeat: 1519 / 404

Let's proceed to step 4:
The number 404 fits into 1519 3 times, leaving a remainder of 307.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 1212 from 1519 leaves us with 307.
Include the next digit (7) from the dividend after 307, then repeat: 3077 / 404

Going ahead to step 5:
3077 divided by 404 is 7 with a remainder of 249.
Put 7 as the next digit of the answer. 
Result so far: 37.0
Deduct 2828 from 3077 and we're left with 249.
Bring next digit (5) of the dividend behind the 249 and repeat the process: 2495 / 404

Advancing to step 6:
If we divide 2495 by 404, we get 6 and a remainder of 71.
Use 6 as the next digit of our solution. 
Result so far: 376.0
Deduct 2424 from 2495 and we're left with 71.
Bring next digit (3) of the dividend behind the 71 and repeat the process: 713 / 404

Going ahead to step 7:
713 divided by 404 is 1 with a remainder of 309.
Use 1 as the next digit of our solution. 
Result so far: 3761.0
If we subtract 404 from 713, we get 309.
Fetch the next digit (3) from the dividend, attach it to 309 and continue: 3093 / 404

Going ahead to step 8:
3093 divided by 404 is 7 with a remainder of 265.
The next digit of our result is 7. 
Result so far: 37617.0
Subtracting 2828 from 3093 leaves us with 265.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2650, and continue the process.

Moving on to step 9:
404 can be fit into 2650 6 times, resulting in a remainder of 226.
The next digit of our result is 6. 
Result so far: 37617.6
Subtract 2424 from 2650 to get 226.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2260, and continue the process.

Step 10:
The number 404 fits into 2260 5 times, leaving a remainder of 240.
Put 5 as the next digit of the answer. 
Result so far: 37617.65
The remainder is 240 after subtracting 2020 from 2260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2400, and continue the process.

Let's proceed to step 11:
If we divide 2400 by 404, we get 5 and a remainder of 380.
Use 5 as the next digit of our solution. 
Result so far: 37617.655
Subtract 2020 from 2400 to get 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3800, and continue the process.

The final result is 37617.655 with a remainder of 0.038.
