We look at the division of 55004576 by 129 
The aim is to understand the frequency of 129 in 55004576.

Going ahead to step 1:
If we divide 5 by 129, we get 0 and a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Fetch the next digit (5) from the dividend, attach it to 5 and continue: 55 / 129

Going ahead to step 2:
If we divide 55 by 129, we get 0 and a remainder of 55.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 55, we get 55.
Bring next digit (0) of the dividend behind the 55 and repeat the process: 550 / 129

Let's proceed to step 3:
When dividing 550 by 129, we get 4 with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 516 from 550 leaves us with 34.
Include the next digit (0) from the dividend after 34, then repeat: 340 / 129

Advancing to step 4:
If we divide 340 by 129, we get 2 and a remainder of 82.
The next digit of our result is 2. 
Result so far: 42.0
The remainder is 82 after subtracting 258 from 340.
Grab the next digit (4) from the dividend, add it to 82, then carry on: 824 / 129

On to step 5:
824 divided by 129 is 6 with a remainder of 50.
Write down 6 as next digit of the result. 
Result so far: 426.0
Deduct 774 from 824 and we're left with 50.
Include the next digit (5) from the dividend after 50, then repeat: 505 / 129

Going ahead to step 6:
505 divided by 129 is 3 with a remainder of 118.
The number 3 becomes the next digit in our result. 
Result so far: 4263.0
Deduct 387 from 505 and we're left with 118.
Fetch the next digit (7) from the dividend, attach it to 118 and continue: 1187 / 129

Going ahead to step 7:
The number 129 fits into 1187 9 times, leaving a remainder of 26.
The next digit of our result is 9. 
Result so far: 42639.0
Subtract 1161 from 1187 to get 26.
Take the next digit (6) from the dividend and append it to 26, then repeat: 266 / 129

Step 8:
129 can be fit into 266 2 times, resulting in a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 426392.0
Subtracting 258 from 266 leaves us 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.

Going ahead to step 9:
80 divided by 129 is 0 with a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 426392.0
Subtract 0 from 80 to get 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 10:
If we divide 800 by 129, we get 6 and a remainder of 26.
Use 6 as the next digit of our solution. 
Result so far: 426392.06
Subtract 774 from 800 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 11:
When dividing 260 by 129, we get 2 with a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 426392.062
If we subtract 258 from 260, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 12:
The number 129 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 426392.062
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 13:
129 can be fit into 200 1 times, resulting in a remainder of 71.
Put 1 as the next digit of the answer. 
Result so far: 426392.06201
The remainder is 71 after subtracting 129 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Advancing to step 14:
710 divided by 129 is 5 with a remainder of 65.
Record the quotient 5 as the next digit in the result. 
Result so far: 426392.062015
Deduct 645 from 710 and we're left with 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Moving on to step 15:
650 divided by 129 is 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 426392.0620155
Deduct 645 from 650 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 426392.0620155 with a remainder of 5e-08.
