We look at the division of 8943545 by 129 
The aim is to understand the frequency of 129 in 8943545.

Moving on to step 1:
8 divided by 129 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (9) from the dividend, add it to 8, then carry on: 89 / 129

Let's proceed to step 2:
If we divide 89 by 129, we get 0 and a remainder of 89.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 89 leaves us with 89.
Fetch the next digit (4) from the dividend, attach it to 89 and continue: 894 / 129

Advancing to step 3:
When dividing 894 by 129, we get 6 with a remainder of 120.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 774 from 894, we get 120.
Bring next digit (3) of the dividend behind the 120 and repeat the process: 1203 / 129

Step 4:
1203 divided by 129 is 9 with a remainder of 42.
The next digit of our result is 9. 
Result so far: 69.0
Subtracting 1161 from 1203 leaves us with 42.
Take the next digit (5) from the dividend and append it to 42, then repeat: 425 / 129

Let's proceed to step 5:
129 goes into 425 3 times with a remainder of 38.
Use 3 as the next digit of our solution. 
Result so far: 693.0
If we take 387 away from 425, we end up with 38.
Append the next digit (4) from the dividend to 38 and continue with: 384 / 129

On to step 6:
384 divided by 129 is 2 with a remainder of 126.
Write down 2 as next digit of the result. 
Result so far: 6932.0
The remainder is 126 after subtracting 258 from 384.
Grab the next digit (5) from the dividend, add it to 126, then carry on: 1265 / 129

On to step 7:
129 can be fit into 1265 9 times, resulting in a remainder of 104.
Write down 9 as next digit of the result. 
Result so far: 69329.0
Deduct 1161 from 1265 and we're left with 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Going ahead to step 8:
129 can be fit into 1040 8 times, resulting in a remainder of 8.
The next digit of our result is 8. 
Result so far: 69329.8
Subtract 1032 from 1040 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.

On to step 9:
If we divide 80 by 129, we get 0 and a remainder of 80.
Put 0 as the next digit of the answer. 
Result so far: 69329.8
Subtracting 0 from 80 leaves us with 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:
800 divided by 129 is 6 with a remainder of 26.
Put 6 as the next digit of the answer. 
Result so far: 69329.806
If we take 774 away from 800, we end up with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 11:
If we divide 260 by 129, we get 2 and a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 69329.8062
If we take 258 away from 260, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 12:
129 can be fit into 20 0 times, resulting in a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 69329.8062
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 13:
129 goes into 200 1 times with a remainder of 71.
The number 1 becomes the next digit in our result. 
Result so far: 69329.806201
If we subtract 129 from 200, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 14:
If we divide 710 by 129, we get 5 and a remainder of 65.
Write down 5 as next digit of the result. 
Result so far: 69329.8062015
If we take 645 away from 710, we end up 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:
When dividing 650 by 129, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 69329.80620155
Subtracting 645 from 650 leaves us 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.

In conclusion, the division gives 69329.80620155 with a balance of 5e-09.
