We look at the division of 11423088 by 129 
The aim is to understand the frequency of 129 in 11423088.

Going ahead to step 1:
129 can be fit into 1 0 times, resulting in a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 129

Step 2:
The number 129 fits into 11 0 times, leaving a remainder of 11.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 11, we get 11.
Grab the next digit (4) from the dividend, add it to 11, then carry on: 114 / 129

Let's proceed to step 3:
When dividing 114 by 129, we get 0 with a remainder of 114.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 114 after subtracting 0 from 114.
Include the next digit (2) from the dividend after 114, then repeat: 1142 / 129

Advancing to step 4:
If we divide 1142 by 129, we get 8 and a remainder of 110.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 1032 from 1142, we get 110.
Grab the next digit (3) from the dividend, add it to 110, then carry on: 1103 / 129

Advancing to step 5:
If we divide 1103 by 129, we get 8 and a remainder of 71.
Use 8 as the next digit of our solution. 
Result so far: 88.0
The remainder is 71 after subtracting 1032 from 1103.
Fetch the next digit (0) from the dividend, attach it to 71 and continue: 710 / 129

On to step 6:
When dividing 710 by 129, we get 5 with a remainder of 65.
The number 5 becomes the next digit in our result. 
Result so far: 885.0
Subtracting 645 from 710 leaves us with 65.
Append the next digit (8) from the dividend to 65 and continue with: 658 / 129

On to step 7:
When dividing 658 by 129, we get 5 with a remainder of 13.
The number 5 becomes the next digit in our result. 
Result so far: 8855.0
Subtracting 645 from 658 leaves us with 13.
Take the next digit (8) from the dividend and append it to 13, then repeat: 138 / 129

Step 8:
The number 129 fits into 138 1 times, leaving a remainder of 9.
The number 1 becomes the next digit in our result. 
Result so far: 88551.0
If we take 129 away from 138, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

On to step 9:
The number 129 fits into 90 0 times, leaving a remainder of 90.
Write down 0 as next digit of the result. 
Result so far: 88551.0
Subtracting 0 from 90 leaves us with 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 900, and continue the process.

Advancing to step 10:
900 divided by 129 is 6 with a remainder of 126.
Record the quotient 6 as the next digit in the result. 
Result so far: 88551.06
Subtracting 774 from 900 leaves us with 126.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1260, and continue the process.

On to step 11:
If we divide 1260 by 129, we get 9 and a remainder of 99.
The next digit of our result is 9. 
Result so far: 88551.069
Deduct 1161 from 1260 and we're left with 99.
Since there are no more digits in the dividend, we add a zero to the remainder making it 990, and continue the process.

On to step 12:
If we divide 990 by 129, we get 7 and a remainder of 87.
Write down 7 as next digit of the result. 
Result so far: 88551.0697
Subtract 903 from 990 to get 87.
Since there are no more digits in the dividend, we add a zero to the remainder making it 870, and continue the process.

Moving on to step 13:
When dividing 870 by 129, we get 6 with a remainder of 96.
Put 6 as the next digit of the answer. 
Result so far: 88551.06976
Subtracting 774 from 870 leaves us with 96.
Since there are no more digits in the dividend, we add a zero to the remainder making it 960, and continue the process.

Going ahead to step 14:
If we divide 960 by 129, we get 7 and a remainder of 57.
The number 7 becomes the next digit in our result. 
Result so far: 88551.069767
Subtract 903 from 960 to get 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 15:
If we divide 570 by 129, we get 4 and a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 88551.0697674
If we subtract 516 from 570, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Moving on to step 16:
129 can be fit into 540 4 times, resulting in a remainder of 24.
Use 4 as the next digit of our solution. 
Result so far: 88551.06976744
If we take 516 away from 540, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

In conclusion, the division gives 88551.06976744 with a balance of 2.4e-08.
