16162192 divided by 129 
The aim is to understand the frequency of 129 in 16162192.

Step 1:
If we divide 1 by 129, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (6) from the dividend to 1 and continue with: 16 / 129

Going ahead to step 2:
129 can be fit into 16 0 times, resulting in a remainder of 16.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 16 leaves us with 16.
Append the next digit (1) from the dividend to 16 and continue with: 161 / 129

Let's proceed to step 3:
161 divided by 129 is 1 with a remainder of 32.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 129 from 161 and we're left with 32.
Append the next digit (6) from the dividend to 32 and continue with: 326 / 129

Moving on to step 4:
129 can be fit into 326 2 times, resulting in a remainder of 68.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtract 258 from 326 to get 68.
Include the next digit (2) from the dividend after 68, then repeat: 682 / 129

Moving on to step 5:
129 can be fit into 682 5 times, resulting in a remainder of 37.
The number 5 becomes the next digit in our result. 
Result so far: 125.0
The remainder is 37 after subtracting 645 from 682.
Include the next digit (1) from the dividend after 37, then repeat: 371 / 129

Going ahead to step 6:
If we divide 371 by 129, we get 2 and a remainder of 113.
Use 2 as the next digit of our solution. 
Result so far: 1252.0
If we subtract 258 from 371, we get 113.
Append the next digit (9) from the dividend to 113 and continue with: 1139 / 129

Step 7:
129 goes into 1139 8 times with a remainder of 107.
Record the quotient 8 as the next digit in the result. 
Result so far: 12528.0
The remainder is 107 after subtracting 1032 from 1139.
Fetch the next digit (2) from the dividend, attach it to 107 and continue: 1072 / 129

Let's proceed to step 8:
The number 129 fits into 1072 8 times, leaving a remainder of 40.
Use 8 as the next digit of our solution. 
Result so far: 125288.0
Deduct 1032 from 1072 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
The number 129 fits into 400 3 times, leaving a remainder of 13.
The number 3 becomes the next digit in our result. 
Result so far: 125288.3
If we subtract 387 from 400, we get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 10:
When dividing 130 by 129, we get 1 with a remainder of 1.
The next digit of our result is 1. 
Result so far: 125288.31
If we subtract 129 from 130, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 11:
129 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 125288.31
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 12:
100 divided by 129 is 0 with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 125288.31
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

The final result is 125288.31 with a remainder of 0.001.
