We look at the division of 23725078 by 424 
The aim is to understand the frequency of 424 in 23725078.

Step 1:
When dividing 2 by 424, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 424

Advancing to step 2:
23 divided by 424 is 0 with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 23, we get 23.
Include the next digit (7) from the dividend after 23, then repeat: 237 / 424

Advancing to step 3:
237 divided by 424 is 0 with a remainder of 237.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 237 after subtracting 0 from 237.
Take the next digit (2) from the dividend and append it to 237, then repeat: 2372 / 424

Moving on to step 4:
2372 divided by 424 is 5 with a remainder of 252.
The next digit of our result is 5. 
Result so far: 5.0
Subtract 2120 from 2372 to get 252.
Fetch the next digit (5) from the dividend, attach it to 252 and continue: 2525 / 424

Going ahead to step 5:
424 goes into 2525 5 times with a remainder of 405.
The next digit of our result is 5. 
Result so far: 55.0
The remainder is 405 after subtracting 2120 from 2525.
Take the next digit (0) from the dividend and append it to 405, then repeat: 4050 / 424

Moving on to step 6:
When dividing 4050 by 424, we get 9 with a remainder of 234.
Record the quotient 9 as the next digit in the result. 
Result so far: 559.0
If we subtract 3816 from 4050, we get 234.
Grab the next digit (7) from the dividend, add it to 234, then carry on: 2347 / 424

Let's proceed to step 7:
2347 divided by 424 is 5 with a remainder of 227.
Record the quotient 5 as the next digit in the result. 
Result so far: 5595.0
If we subtract 2120 from 2347, we get 227.
Append the next digit (8) from the dividend to 227 and continue with: 2278 / 424

Let's proceed to step 8:
2278 divided by 424 is 5 with a remainder of 158.
Record the quotient 5 as the next digit in the result. 
Result so far: 55955.0
Deduct 2120 from 2278 and we're left with 158.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1580, and continue the process.

Let's proceed to step 9:
The number 424 fits into 1580 3 times, leaving a remainder of 308.
The number 3 becomes the next digit in our result. 
Result so far: 55955.3
If we take 1272 away from 1580, we end up with 308.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3080, and continue the process.

Step 10:
If we divide 3080 by 424, we get 7 and a remainder of 112.
Put 7 as the next digit of the answer. 
Result so far: 55955.37
If we take 2968 away from 3080, we end up with 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 11:
1120 divided by 424 is 2 with a remainder of 272.
The next digit of our result is 2. 
Result so far: 55955.372
Subtracting 848 from 1120 leaves us with 272.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2720, and continue the process.

Let's proceed to step 12:
424 goes into 2720 6 times with a remainder of 176.
The next digit of our result is 6. 
Result so far: 55955.3726
Subtracting 2544 from 2720 leaves us with 176.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1760, and continue the process.

Step 13:
If we divide 1760 by 424, we get 4 and a remainder of 64.
The number 4 becomes the next digit in our result. 
Result so far: 55955.37264
Subtracting 1696 from 1760 leaves us with 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 14:
424 goes into 640 1 times with a remainder of 216.
The next digit of our result is 1. 
Result so far: 55955.372641
Subtracting 424 from 640 leaves us with 216.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2160, and continue the process.

Step 15:
If we divide 2160 by 424, we get 5 and a remainder of 40.
Use 5 as the next digit of our solution. 
Result so far: 55955.3726415
Deduct 2120 from 2160 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 16:
400 divided by 424 is 0 with a remainder of 400.
Write down 0 as next digit of the result. 
Result so far: 55955.3726415
If we take 0 away from 400, we end up with 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4000, and continue the process.

After the division, we end up with 55955.3726415 and a remainder of 4e-07.
