389226 divided by 15 
The aim is to understand the frequency of 15 in 389226.

Advancing to step 1:
15 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 3 leaves us with 3.
Take the next digit (8) from the dividend and append it to 3, then repeat: 38 / 15

Advancing to step 2:
15 goes into 38 2 times with a remainder of 8.
Put 2 as the next digit of the answer. 
Result so far: 2.0
If we take 30 away from 38, we end up with 8.
Include the next digit (9) from the dividend after 8, then repeat: 89 / 15

Let's proceed to step 3:
15 goes into 89 5 times with a remainder of 14.
Put 5 as the next digit of the answer. 
Result so far: 25.0
The remainder is 14 after subtracting 75 from 89.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 15

Step 4:
15 can be fit into 142 9 times, resulting in a remainder of 7.
The next digit of our result is 9. 
Result so far: 259.0
Subtracting 135 from 142 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 15

On to step 5:
The number 15 fits into 72 4 times, leaving a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 2594.0
Subtracting 60 from 72 leaves us with 12.
Grab the next digit (6) from the dividend, add it to 12, then carry on: 126 / 15

On to step 6:
The number 15 fits into 126 8 times, leaving a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 25948.0
If we take 120 away from 126, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
15 goes into 60 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 25948.4
The remainder is 0 after subtracting 60 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
0 divided by 15 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 25948.4
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.

Step 9:
When dividing 0 by 15, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 25948.4
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.

In conclusion, the division gives 25948.4 with a balance of 0.0.
