We're dividing 93722903 by 129 
The aim is to understand the frequency of 129 in 93722903.

Let's proceed to step 1:
When dividing 9 by 129, we get 0 with a remainder of 9.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (3) from the dividend, add it to 9, then carry on: 93 / 129

On to step 2:
When dividing 93 by 129, we get 0 with a remainder of 93.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 93 and we're left with 93.
Take the next digit (7) from the dividend and append it to 93, then repeat: 937 / 129

Step 3:
129 goes into 937 7 times with a remainder of 34.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we take 903 away from 937, we end up with 34.
Append the next digit (2) from the dividend to 34 and continue with: 342 / 129

Step 4:
When dividing 342 by 129, we get 2 with a remainder of 84.
The number 2 becomes the next digit in our result. 
Result so far: 72.0
Deduct 258 from 342 and we're left with 84.
Append the next digit (2) from the dividend to 84 and continue with: 842 / 129

Advancing to step 5:
When dividing 842 by 129, we get 6 with a remainder of 68.
Record the quotient 6 as the next digit in the result. 
Result so far: 726.0
Subtracting 774 from 842 leaves us with 68.
Grab the next digit (9) from the dividend, add it to 68, then carry on: 689 / 129

Step 6:
The number 129 fits into 689 5 times, leaving a remainder of 44.
The next digit of our result is 5. 
Result so far: 7265.0
If we take 645 away from 689, we end up with 44.
Grab the next digit (0) from the dividend, add it to 44, then carry on: 440 / 129

Going ahead to step 7:
440 divided by 129 is 3 with a remainder of 53.
Put 3 as the next digit of the answer. 
Result so far: 72653.0
If we take 387 away from 440, we end up with 53.
Include the next digit (3) from the dividend after 53, then repeat: 533 / 129

Moving on to step 8:
533 divided by 129 is 4 with a remainder of 17.
The number 4 becomes the next digit in our result. 
Result so far: 726534.0
Subtract 516 from 533 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 9:
129 goes into 170 1 times with a remainder of 41.
Record the quotient 1 as the next digit in the result. 
Result so far: 726534.1
Deduct 129 from 170 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.

Going ahead to step 10:
When dividing 410 by 129, we get 3 with a remainder of 23.
The number 3 becomes the next digit in our result. 
Result so far: 726534.13
If we take 387 away from 410, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Let's proceed to step 11:
When dividing 230 by 129, we get 1 with a remainder of 101.
Put 1 as the next digit of the answer. 
Result so far: 726534.131
Deduct 129 from 230 and we're left with 101.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1010, and continue the process.

Step 12:
If we divide 1010 by 129, we get 7 and a remainder of 107.
Write down 7 as next digit of the result. 
Result so far: 726534.1317
Subtracting 903 from 1010 leaves us with 107.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1070, and continue the process.

Let's proceed to step 13:
129 goes into 1070 8 times with a remainder of 38.
The number 8 becomes the next digit in our result. 
Result so far: 726534.13178
If we take 1032 away from 1070, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 14:
129 can be fit into 380 2 times, resulting in a remainder of 122.
The number 2 becomes the next digit in our result. 
Result so far: 726534.131782
Subtracting 258 from 380 leaves us with 122.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1220, and continue the process.

Step 15:
129 can be fit into 1220 9 times, resulting in a remainder of 59.
Write down 9 as next digit of the result. 
Result so far: 726534.1317829
If we take 1161 away from 1220, we end up with 59.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Let's proceed to step 16:
When dividing 590 by 129, we get 4 with a remainder of 74.
The next digit of our result is 4. 
Result so far: 726534.13178294
The remainder is 74 after subtracting 516 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

The final outcome is 726534.13178294, with a leftover of 7.4e-08.
