69011679 ÷ 129 
The aim is to understand the frequency of 129 in 69011679.

Let's proceed to step 1:
When dividing 6 by 129, we get 0 with a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 129

Moving on to step 2:
When dividing 69 by 129, we get 0 with a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 69 after subtracting 0 from 69.
Grab the next digit (0) from the dividend, add it to 69, then carry on: 690 / 129

Moving on to step 3:
The number 129 fits into 690 5 times, leaving a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 645 from 690 leaves us with 45.
Grab the next digit (1) from the dividend, add it to 45, then carry on: 451 / 129

On to step 4:
451 divided by 129 is 3 with a remainder of 64.
Use 3 as the next digit of our solution. 
Result so far: 53.0
Subtracting 387 from 451 leaves us with 64.
Include the next digit (1) from the dividend after 64, then repeat: 641 / 129

Let's proceed to step 5:
When dividing 641 by 129, we get 4 with a remainder of 125.
Record the quotient 4 as the next digit in the result. 
Result so far: 534.0
Deduct 516 from 641 and we're left with 125.
Append the next digit (6) from the dividend to 125 and continue with: 1256 / 129

Going ahead to step 6:
129 can be fit into 1256 9 times, resulting in a remainder of 95.
The number 9 becomes the next digit in our result. 
Result so far: 5349.0
Subtracting 1161 from 1256 leaves us with 95.
Append the next digit (7) from the dividend to 95 and continue with: 957 / 129

Step 7:
957 divided by 129 is 7 with a remainder of 54.
The number 7 becomes the next digit in our result. 
Result so far: 53497.0
Deduct 903 from 957 and we're left with 54.
Grab the next digit (9) from the dividend, add it to 54, then carry on: 549 / 129

Step 8:
When dividing 549 by 129, we get 4 with a remainder of 33.
The next digit of our result is 4. 
Result so far: 534974.0
Deduct 516 from 549 and we're left with 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 9:
If we divide 330 by 129, we get 2 and a remainder of 72.
The number 2 becomes the next digit in our result. 
Result so far: 534974.2
If we take 258 away from 330, we end up with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Going ahead to step 10:
129 can be fit into 720 5 times, resulting in a remainder of 75.
The next digit of our result is 5. 
Result so far: 534974.25
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.

On to step 11:
750 divided by 129 is 5 with a remainder of 105.
Record the quotient 5 as the next digit in the result. 
Result so far: 534974.255
Subtracting 645 from 750 leaves us 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.

In conclusion, the division gives 534974.255 with a balance of 0.0105.
