Let's divide 16923296 by 15
The aim is to understand the frequency of 15 in 16923296.

Step 1:
15 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
Subtract 0 from 1 to get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 15

Step 2:
When dividing 16 by 15, we get 1 with a remainder of 1.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
The remainder is 1 after subtracting 15 from 16.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 15

Let's proceed to step 3:
15 goes into 19 1 times with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
If we take 15 away from 19, we end up with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 15

Step 4:
If we divide 42 by 15, we get 2 and a remainder of 12.
Write down 2 as next digit of the result. 
Result so far: 112.0
If we subtract 30 from 42, we get 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 15

Step 5:
When dividing 123 by 15, we get 8 with a remainder of 3.
Use 8 as the next digit of our solution. 
Result so far: 1128.0
If we subtract 120 from 123, we get 3.
Grab the next digit (2) from the dividend, add it to 3, then carry on: 32 / 15

Let's proceed to step 6:
15 goes into 32 2 times with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 11282.0
Subtract 30 from 32 to get 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 15

Moving on to step 7:
15 goes into 29 1 times with a remainder of 14.
The next digit of our result is 1. 
Result so far: 112821.0
Subtract 15 from 29 to get 14.
Append the next digit (6) from the dividend to 14 and continue with: 146 / 15

On to step 8:
When dividing 146 by 15, we get 9 with a remainder of 11.
The number 9 becomes the next digit in our result. 
Result so far: 1128219.0
Subtract 135 from 146 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
110 divided by 15 is 7 with a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 1128219.7
Deduct 105 from 110 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 10:
The number 15 fits into 50 3 times, leaving a remainder of 5.
The next digit of our result is 3. 
Result so far: 1128219.73
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 11:
When dividing 50 by 15, we get 3 with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 1128219.733
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

After the division, we end up with 1128219.733 and a remainder of 0.0005.
