We look at the division of 24161881 by 624 
The aim is to understand the frequency of 624 in 24161881.

Advancing to step 1:
If we divide 2 by 624, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 624

Moving on to step 2:
When dividing 24 by 624, we get 0 with a remainder of 24.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 24, we end up with 24.
Append the next digit (1) from the dividend to 24 and continue with: 241 / 624

Advancing to step 3:
624 goes into 241 0 times with a remainder of 241.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 241 to get 241.
Include the next digit (6) from the dividend after 241, then repeat: 2416 / 624

Moving on to step 4:
624 can be fit into 2416 3 times, resulting in a remainder of 544.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 1872 away from 2416, we end up with 544.
Append the next digit (1) from the dividend to 544 and continue with: 5441 / 624

Moving on to step 5:
The number 624 fits into 5441 8 times, leaving a remainder of 449.
Use 8 as the next digit of our solution. 
Result so far: 38.0
If we subtract 4992 from 5441, we get 449.
Include the next digit (8) from the dividend after 449, then repeat: 4498 / 624

Advancing to step 6:
4498 divided by 624 is 7 with a remainder of 130.
Write down 7 as next digit of the result. 
Result so far: 387.0
If we take 4368 away from 4498, we end up with 130.
Grab the next digit (8) from the dividend, add it to 130, then carry on: 1308 / 624

On to step 7:
1308 divided by 624 is 2 with a remainder of 60.
The next digit of our result is 2. 
Result so far: 3872.0
If we subtract 1248 from 1308, we get 60.
Grab the next digit (1) from the dividend, add it to 60, then carry on: 601 / 624

Advancing to step 8:
The number 624 fits into 601 0 times, leaving a remainder of 601.
Use 0 as the next digit of our solution. 
Result so far: 38720.0
Subtract 0 from 601 to get 601.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6010, and continue the process.

Step 9:
If we divide 6010 by 624, we get 9 and a remainder of 394.
Use 9 as the next digit of our solution. 
Result so far: 38720.9
If we subtract 5616 from 6010, we get 394.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3940, and continue the process.

Step 10:
If we divide 3940 by 624, we get 6 and a remainder of 196.
Put 6 as the next digit of the answer. 
Result so far: 38720.96
Deduct 3744 from 3940 and we're left with 196.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1960, and continue the process.

Step 11:
624 can be fit into 1960 3 times, resulting in a remainder of 88.
Record the quotient 3 as the next digit in the result. 
Result so far: 38720.963
Deduct 1872 from 1960 and we're left with 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Moving on to step 12:
880 divided by 624 is 1 with a remainder of 256.
The next digit of our result is 1. 
Result so far: 38720.9631
Subtracting 624 from 880 leaves us 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.

Moving on to step 13:
2560 divided by 624 is 4 with a remainder of 64.
Put 4 as the next digit of the answer. 
Result so far: 38720.96314
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 14:
If we divide 640 by 624, we get 1 and a remainder of 16.
Put 1 as the next digit of the answer. 
Result so far: 38720.963141
If we take 624 away from 640, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

On to step 15:
If we divide 160 by 624, we get 0 and a remainder of 160.
Write down 0 as next digit of the result. 
Result so far: 38720.963141
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.

Let's proceed to step 16:
624 goes into 1600 2 times with a remainder of 352.
Write down 2 as next digit of the result. 
Result so far: 38720.96314102
If we take 1248 away from 1600, we end up with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

The quotient of the division is 38720.96314102, and the remainder is 3.52e-07.
