We look at the division of 129357 by 44 
The aim is to understand the frequency of 44 in 129357.

Advancing to step 1:
If we divide 1 by 44, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 44

Moving on to step 2:
12 divided by 44 is 0 with a remainder of 12.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 12, we get 12.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 44

Going ahead to step 3:
129 divided by 44 is 2 with a remainder of 41.
The next digit of our result is 2. 
Result so far: 2.0
The remainder is 41 after subtracting 88 from 129.
Bring next digit (3) of the dividend behind the 41 and repeat the process: 413 / 44

On to step 4:
The number 44 fits into 413 9 times, leaving a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 29.0
Subtracting 396 from 413 leaves us with 17.
Take the next digit (5) from the dividend and append it to 17, then repeat: 175 / 44

Let's proceed to step 5:
When dividing 175 by 44, we get 3 with a remainder of 43.
Write down 3 as next digit of the result. 
Result so far: 293.0
The remainder is 43 after subtracting 132 from 175.
Append the next digit (7) from the dividend to 43 and continue with: 437 / 44

Moving on to step 6:
The number 44 fits into 437 9 times, leaving a remainder of 41.
Write down 9 as next digit of the result. 
Result so far: 2939.0
Deduct 396 from 437 and we're left with 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

Advancing to step 7:
When dividing 410 by 44, we get 9 with a remainder of 14.
The number 9 becomes the next digit in our result. 
Result so far: 2939.9
The remainder is 14 after subtracting 396 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 8:
If we divide 140 by 44, we get 3 and a remainder of 8.
The number 3 becomes the next digit in our result. 
Result so far: 2939.93
The remainder is 8 after subtracting 132 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
When dividing 80 by 44, we get 1 with a remainder of 36.
The next digit of our result is 1. 
Result so far: 2939.931
If we take 44 away from 80, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 10:
If we divide 360 by 44, we get 8 and a remainder of 8.
The next digit of our result is 8. 
Result so far: 2939.9318
Subtract 352 from 360 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
44 can be fit into 80 1 times, resulting in a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 2939.93181
Subtracting 44 from 80 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 12:
44 can be fit into 360 8 times, resulting in a remainder of 8.
Record the quotient 8 as the next digit in the result. 
Result so far: 2939.931818
Deduct 352 from 360 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 13:
The number 44 fits into 80 1 times, leaving a remainder of 36.
Record the quotient 1 as the next digit in the result. 
Result so far: 2939.9318181
The remainder is 36 after subtracting 44 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 14:
44 can be fit into 360 8 times, resulting in a remainder of 8.
Write down 8 as next digit of the result. 
Result so far: 2939.93181818
If we take 352 away from 360, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 2939.93181818, with a leftover of 8e-09.
