Let's divide 790842 by 15
The aim is to understand the frequency of 15 in 790842.

On to step 1:
When dividing 7 by 15, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Include the next digit (9) from the dividend after 7, then repeat: 79 / 15

Moving on to step 2:
15 goes into 79 5 times with a remainder of 4.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we take 75 away from 79, we end up with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 15

Going ahead to step 3:
When dividing 40 by 15, we get 2 with a remainder of 10.
Write down 2 as next digit of the result. 
Result so far: 52.0
If we take 30 away from 40, we end up with 10.
Grab the next digit (8) from the dividend, add it to 10, then carry on: 108 / 15

Moving on to step 4:
The number 15 fits into 108 7 times, leaving a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 527.0
If we subtract 105 from 108, we get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 15

Moving on to step 5:
15 goes into 34 2 times with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 5272.0
Deduct 30 from 34 and we're left with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 15

Let's proceed to step 6:
42 divided by 15 is 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 52722.0
Subtract 30 from 42 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 7:
15 can be fit into 120 8 times, resulting in a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 52722.8
Subtracting 120 from 120 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.

Let's proceed to step 8:
15 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 52722.8
If we take 0 away from 0, we end up 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:
If we divide 0 by 15, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 52722.8
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 52722.8 with a balance of 0.0.
