We look at the division of 99242272 by 624 
The aim is to understand the frequency of 624 in 99242272.

Advancing to step 1:
9 divided by 624 is 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 9, we get 9.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 624

Going ahead to step 2:
624 goes into 99 0 times with a remainder of 99.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 99 and we're left with 99.
Include the next digit (2) from the dividend after 99, then repeat: 992 / 624

Moving on to step 3:
The number 624 fits into 992 1 times, leaving a remainder of 368.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 624 from 992, we get 368.
Fetch the next digit (4) from the dividend, attach it to 368 and continue: 3684 / 624

Step 4:
If we divide 3684 by 624, we get 5 and a remainder of 564.
The next digit of our result is 5. 
Result so far: 15.0
If we subtract 3120 from 3684, we get 564.
Take the next digit (2) from the dividend and append it to 564, then repeat: 5642 / 624

Advancing to step 5:
5642 divided by 624 is 9 with a remainder of 26.
The next digit of our result is 9. 
Result so far: 159.0
Subtracting 5616 from 5642 leaves us with 26.
Include the next digit (2) from the dividend after 26, then repeat: 262 / 624

Moving on to step 6:
If we divide 262 by 624, we get 0 and a remainder of 262.
Record the quotient 0 as the next digit in the result. 
Result so far: 1590.0
If we take 0 away from 262, we end up with 262.
Append the next digit (7) from the dividend to 262 and continue with: 2627 / 624

Let's proceed to step 7:
If we divide 2627 by 624, we get 4 and a remainder of 131.
The number 4 becomes the next digit in our result. 
Result so far: 15904.0
Subtracting 2496 from 2627 leaves us with 131.
Include the next digit (2) from the dividend after 131, then repeat: 1312 / 624

Advancing to step 8:
When dividing 1312 by 624, we get 2 with a remainder of 64.
Use 2 as the next digit of our solution. 
Result so far: 159042.0
Subtracting 1248 from 1312 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.

Let's proceed to step 9:
When dividing 640 by 624, we get 1 with a remainder of 16.
Write down 1 as next digit of the result. 
Result so far: 159042.1
If we subtract 624 from 640, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 10:
624 goes into 160 0 times with a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 159042.1
Subtract 0 from 160 to get 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

Going ahead to step 11:
The number 624 fits into 1600 2 times, leaving a remainder of 352.
Write down 2 as next digit of the result. 
Result so far: 159042.102
Subtract 1248 from 1600 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Moving on to step 12:
624 goes into 3520 5 times with a remainder of 400.
The number 5 becomes the next digit in our result. 
Result so far: 159042.1025
If we take 3120 away from 3520, 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.

Step 13:
When dividing 4000 by 624, we get 6 with a remainder of 256.
The number 6 becomes the next digit in our result. 
Result so far: 159042.10256
Deduct 3744 from 4000 and we're left with 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Let's proceed to step 14:
When dividing 2560 by 624, we get 4 with a remainder of 64.
The next digit of our result is 4. 
Result so far: 159042.102564
Subtracting 2496 from 2560 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.

Step 15:
When dividing 640 by 624, we get 1 with a remainder of 16.
Use 1 as the next digit of our solution. 
Result so far: 159042.1025641
The remainder is 16 after subtracting 624 from 640.
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 16:
160 divided by 624 is 0 with a remainder of 160.
Record the quotient 0 as the next digit in the result. 
Result so far: 159042.1025641
The remainder is 160 after subtracting 0 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1600, and continue the process.

The final outcome is 159042.1025641, with a leftover of 1.6e-07.
