We look at the division of 195469 by 15 
The aim is to understand the frequency of 15 in 195469.

Let's proceed to step 1:
15 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 15

On to step 2:
15 can be fit into 19 1 times, resulting in a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 4 after subtracting 15 from 19.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 15

On to step 3:
15 goes into 45 3 times with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtracting 45 from 45 leaves us with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 15

Advancing to step 4:
The number 15 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 130.0
Subtract 0 from 4 to get 4.
Grab the next digit (6) from the dividend, add it to 4, then carry on: 46 / 15

On to step 5:
When dividing 46 by 15, we get 3 with a remainder of 1.
Write down 3 as next digit of the result. 
Result so far: 1303.0
Subtract 45 from 46 to get 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 15

Moving on to step 6:
The number 15 fits into 19 1 times, leaving a remainder of 4.
Write down 1 as next digit of the result. 
Result so far: 13031.0
If we subtract 15 from 19, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
40 divided by 15 is 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 13031.2
If we take 30 away from 40, 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.

Moving on to step 8:
15 goes into 100 6 times with a remainder of 10.
The next digit of our result is 6. 
Result so far: 13031.26
Subtracting 90 from 100 leaves us 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.

Step 9:
If we divide 100 by 15, we get 6 and a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 13031.266
If we take 90 away from 100, 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.

The final outcome is 13031.266, with a leftover of 0.001.
