We look at the division of 43029108 by 872 
The aim is to understand the frequency of 872 in 43029108.

Going ahead to step 1:
872 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 872

Advancing to step 2:
When dividing 43 by 872, we get 0 with a remainder of 43.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Append the next digit (0) from the dividend to 43 and continue with: 430 / 872

Advancing to step 3:
872 can be fit into 430 0 times, resulting in a remainder of 430.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 430 to get 430.
Append the next digit (2) from the dividend to 430 and continue with: 4302 / 872

Let's proceed to step 4:
When dividing 4302 by 872, we get 4 with a remainder of 814.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 3488 from 4302 leaves us with 814.
Include the next digit (9) from the dividend after 814, then repeat: 8149 / 872

Step 5:
872 can be fit into 8149 9 times, resulting in a remainder of 301.
Use 9 as the next digit of our solution. 
Result so far: 49.0
Subtract 7848 from 8149 to get 301.
Grab the next digit (1) from the dividend, add it to 301, then carry on: 3011 / 872

Going ahead to step 6:
If we divide 3011 by 872, we get 3 and a remainder of 395.
Put 3 as the next digit of the answer. 
Result so far: 493.0
Deduct 2616 from 3011 and we're left with 395.
Append the next digit (0) from the dividend to 395 and continue with: 3950 / 872

Moving on to step 7:
When dividing 3950 by 872, we get 4 with a remainder of 462.
The next digit of our result is 4. 
Result so far: 4934.0
Deduct 3488 from 3950 and we're left with 462.
Append the next digit (8) from the dividend to 462 and continue with: 4628 / 872

On to step 8:
When dividing 4628 by 872, we get 5 with a remainder of 268.
Use 5 as the next digit of our solution. 
Result so far: 49345.0
The remainder is 268 after subtracting 4360 from 4628.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2680, and continue the process.

Advancing to step 9:
872 goes into 2680 3 times with a remainder of 64.
The number 3 becomes the next digit in our result. 
Result so far: 49345.3
Deduct 2616 from 2680 and we're left 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.

Advancing to step 10:
If we divide 640 by 872, we get 0 and a remainder of 640.
The next digit of our result is 0. 
Result so far: 49345.3
If we subtract 0 from 640, we get 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Let's proceed to step 11:
If we divide 6400 by 872, we get 7 and a remainder of 296.
Put 7 as the next digit of the answer. 
Result so far: 49345.307
If we take 6104 away from 6400, we end up with 296.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2960, and continue the process.

Moving on to step 12:
872 goes into 2960 3 times with a remainder of 344.
The next digit of our result is 3. 
Result so far: 49345.3073
The remainder is 344 after subtracting 2616 from 2960.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Going ahead to step 13:
872 can be fit into 3440 3 times, resulting in a remainder of 824.
Record the quotient 3 as the next digit in the result. 
Result so far: 49345.30733
Subtract 2616 from 3440 to get 824.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8240, and continue the process.

The final result is 49345.30733 with a remainder of 0.000824.
