3069783 divided by 15 
The aim is to understand the frequency of 15 in 3069783.

Advancing to step 1:
3 divided by 15 is 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 15

Let's proceed to step 2:
30 divided by 15 is 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
Subtracting 30 from 30 leaves us with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 15

Advancing to step 3:
15 can be fit into 6 0 times, resulting in a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we take 0 away from 6, we end up with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 15

Let's proceed to step 4:
The number 15 fits into 69 4 times, leaving a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 204.0
The remainder is 9 after subtracting 60 from 69.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 15

Advancing to step 5:
If we divide 97 by 15, we get 6 and a remainder of 7.
The number 6 becomes the next digit in our result. 
Result so far: 2046.0
If we take 90 away from 97, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 15

Moving on to step 6:
The number 15 fits into 78 5 times, leaving a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 20465.0
Subtract 75 from 78 to get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 15

Going ahead to step 7:
The number 15 fits into 33 2 times, leaving a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 204652.0
The remainder is 3 after subtracting 30 from 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Going ahead to step 8:
15 can be fit into 30 2 times, resulting in a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 204652.2
If we subtract 30 from 30, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 9:
The number 15 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 204652.2
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
0 divided by 15 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 204652.2
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The final outcome is 204652.2, with a leftover of 0.0.
