We're dividing 34130436 by 129 
The aim is to understand the frequency of 129 in 34130436.

Moving on to step 1:
If we divide 3 by 129, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 129

Moving on to step 2:
34 divided by 129 is 0 with a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Fetch the next digit (1) from the dividend, attach it to 34 and continue: 341 / 129

Going ahead to step 3:
The number 129 fits into 341 2 times, leaving a remainder of 83.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 258 from 341 to get 83.
Take the next digit (3) from the dividend and append it to 83, then repeat: 833 / 129

Let's proceed to step 4:
When dividing 833 by 129, we get 6 with a remainder of 59.
The number 6 becomes the next digit in our result. 
Result so far: 26.0
Subtracting 774 from 833 leaves us with 59.
Append the next digit (0) from the dividend to 59 and continue with: 590 / 129

Moving on to step 5:
590 divided by 129 is 4 with a remainder of 74.
Put 4 as the next digit of the answer. 
Result so far: 264.0
Deduct 516 from 590 and we're left with 74.
Bring next digit (4) of the dividend behind the 74 and repeat the process: 744 / 129

Moving on to step 6:
129 can be fit into 744 5 times, resulting in a remainder of 99.
Write down 5 as next digit of the result. 
Result so far: 2645.0
The remainder is 99 after subtracting 645 from 744.
Append the next digit (3) from the dividend to 99 and continue with: 993 / 129

Going ahead to step 7:
993 divided by 129 is 7 with a remainder of 90.
The number 7 becomes the next digit in our result. 
Result so far: 26457.0
If we take 903 away from 993, we end up with 90.
Include the next digit (6) from the dividend after 90, then repeat: 906 / 129

Advancing to step 8:
129 can be fit into 906 7 times, resulting in a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 264577.0
The remainder is 3 after subtracting 903 from 906.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 9:
129 goes into 30 0 times with a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 264577.0
If we subtract 0 from 30, we get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Moving on to step 10:
129 can be fit into 300 2 times, resulting in a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 264577.02
If we take 258 away from 300, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 11:
420 divided by 129 is 3 with a remainder of 33.
The number 3 becomes the next digit in our result. 
Result so far: 264577.023
The remainder is 33 after subtracting 387 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 12:
When dividing 330 by 129, we get 2 with a remainder of 72.
Write down 2 as next digit of the result. 
Result so far: 264577.0232
Subtract 258 from 330 to get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Moving on to step 13:
129 goes into 720 5 times with a remainder of 75.
Write down 5 as next digit of the result. 
Result so far: 264577.02325
Subtracting 645 from 720 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Step 14:
When dividing 750 by 129, we get 5 with a remainder of 105.
The number 5 becomes the next digit in our result. 
Result so far: 264577.023255
If we take 645 away from 750, we end up with 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

The quotient of the division is 264577.023255, and the remainder is 1.05e-05.
