We're dividing 73546675 by 129 
The aim is to understand the frequency of 129 in 73546675.

Going ahead to step 1:
If we divide 7 by 129, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 129

Advancing to step 2:
129 goes into 73 0 times with a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 73 to get 73.
Include the next digit (5) from the dividend after 73, then repeat: 735 / 129

Advancing to step 3:
735 divided by 129 is 5 with a remainder of 90.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 645 away from 735, we end up with 90.
Fetch the next digit (4) from the dividend, attach it to 90 and continue: 904 / 129

Moving on to step 4:
When dividing 904 by 129, we get 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 57.0
Subtracting 903 from 904 leaves us with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 129

Moving on to step 5:
129 goes into 16 0 times with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 570.0
Deduct 0 from 16 and we're left with 16.
Append the next digit (6) from the dividend to 16 and continue with: 166 / 129

Let's proceed to step 6:
129 can be fit into 166 1 times, resulting in a remainder of 37.
Put 1 as the next digit of the answer. 
Result so far: 5701.0
The remainder is 37 after subtracting 129 from 166.
Fetch the next digit (7) from the dividend, attach it to 37 and continue: 377 / 129

Let's proceed to step 7:
377 divided by 129 is 2 with a remainder of 119.
Record the quotient 2 as the next digit in the result. 
Result so far: 57012.0
If we subtract 258 from 377, we get 119.
Include the next digit (5) from the dividend after 119, then repeat: 1195 / 129

Going ahead to step 8:
129 goes into 1195 9 times with a remainder of 34.
Put 9 as the next digit of the answer. 
Result so far: 570129.0
Deduct 1161 from 1195 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Going ahead to step 9:
129 goes into 340 2 times with a remainder of 82.
Record the quotient 2 as the next digit in the result. 
Result so far: 570129.2
If we subtract 258 from 340, we get 82.
Since there are no more digits in the dividend, we add a zero to the remainder making it 820, and continue the process.

Going ahead to step 10:
If we divide 820 by 129, we get 6 and a remainder of 46.
The next digit of our result is 6. 
Result so far: 570129.26
If we subtract 774 from 820, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 11:
129 goes into 460 3 times with a remainder of 73.
Write down 3 as next digit of the result. 
Result so far: 570129.263
The remainder is 73 after subtracting 387 from 460.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 12:
The number 129 fits into 730 5 times, leaving a remainder of 85.
Put 5 as the next digit of the answer. 
Result so far: 570129.2635
Subtract 645 from 730 to get 85.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 13:
If we divide 850 by 129, we get 6 and a remainder of 76.
Record the quotient 6 as the next digit in the result. 
Result so far: 570129.26356
The remainder is 76 after subtracting 774 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Step 14:
760 divided by 129 is 5 with a remainder of 115.
The next digit of our result is 5. 
Result so far: 570129.263565
The remainder is 115 after subtracting 645 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Going ahead to step 15:
When dividing 1150 by 129, we get 8 with a remainder of 118.
The next digit of our result is 8. 
Result so far: 570129.2635658
The remainder is 118 after subtracting 1032 from 1150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1180, and continue the process.

Moving on to step 16:
129 goes into 1180 9 times with a remainder of 19.
Record the quotient 9 as the next digit in the result. 
Result so far: 570129.26356589
Deduct 1161 from 1180 and we're left with 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

In conclusion, the division gives 570129.26356589 with a balance of 1.9e-08.
