Let's divide 19888969 by 165
The aim is to understand the frequency of 165 in 19888969.

Moving on to step 1:
165 can be fit into 1 0 times, resulting in a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Include the next digit (9) from the dividend after 1, then repeat: 19 / 165

On to step 2:
If we divide 19 by 165, we get 0 and a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 19, we end up with 19.
Bring next digit (8) of the dividend behind the 19 and repeat the process: 198 / 165

Moving on to step 3:
The number 165 fits into 198 1 times, leaving a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 33 after subtracting 165 from 198.
Grab the next digit (8) from the dividend, add it to 33, then carry on: 338 / 165

On to step 4:
165 can be fit into 338 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 12.0
Subtracting 330 from 338 leaves us with 8.
Grab the next digit (8) from the dividend, add it to 8, then carry on: 88 / 165

Moving on to step 5:
165 goes into 88 0 times with a remainder of 88.
Write down 0 as next digit of the result. 
Result so far: 120.0
Subtract 0 from 88 to get 88.
Take the next digit (9) from the dividend and append it to 88, then repeat: 889 / 165

Advancing to step 6:
When dividing 889 by 165, we get 5 with a remainder of 64.
Put 5 as the next digit of the answer. 
Result so far: 1205.0
Subtracting 825 from 889 leaves us with 64.
Grab the next digit (6) from the dividend, add it to 64, then carry on: 646 / 165

Advancing to step 7:
646 divided by 165 is 3 with a remainder of 151.
Put 3 as the next digit of the answer. 
Result so far: 12053.0
Deduct 495 from 646 and we're left with 151.
Bring next digit (9) of the dividend behind the 151 and repeat the process: 1519 / 165

On to step 8:
165 goes into 1519 9 times with a remainder of 34.
Use 9 as the next digit of our solution. 
Result so far: 120539.0
If we subtract 1485 from 1519, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
The number 165 fits into 340 2 times, leaving a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 120539.2
If we take 330 away from 340, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
165 goes into 100 0 times with a remainder of 100.
Use 0 as the next digit of our solution. 
Result so far: 120539.2
Subtract 0 from 100 to get 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 11:
If we divide 1000 by 165, we get 6 and a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 120539.206
Subtract 990 from 1000 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 12:
When dividing 100 by 165, we get 0 with a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 120539.206
Subtracting 0 from 100 leaves us with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Step 13:
When dividing 1000 by 165, we get 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 120539.20606
If we take 990 away from 1000, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
The number 165 fits into 100 0 times, leaving a remainder of 100.
The number 0 becomes the next digit in our result. 
Result so far: 120539.20606
If we take 0 away from 100, we end up with 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Let's proceed to step 15:
The number 165 fits into 1000 6 times, leaving a remainder of 10.
The number 6 becomes the next digit in our result. 
Result so far: 120539.2060606
Subtract 990 from 1000 to get 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 16:
100 divided by 165 is 0 with a remainder of 100.
Put 0 as the next digit of the answer. 
Result so far: 120539.2060606
If we take 0 away from 100, we end up with 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 outcome is 120539.2060606, with a leftover of 1e-07.
