797041 ÷ 15 
The aim is to understand the frequency of 15 in 797041.

Let's proceed to step 1:
If we divide 7 by 15, we get 0 and a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (9) from the dividend, add it to 7, then carry on: 79 / 15

Step 2:
The number 15 fits into 79 5 times, leaving a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 75 from 79 and we're left with 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 15

Moving on to step 3:
15 can be fit into 47 3 times, resulting in a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 53.0
The remainder is 2 after subtracting 45 from 47.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 15

Going ahead to step 4:
If we divide 20 by 15, we get 1 and a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 531.0
Subtract 15 from 20 to get 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 15

Step 5:
54 divided by 15 is 3 with a remainder of 9.
Put 3 as the next digit of the answer. 
Result so far: 5313.0
The remainder is 9 after subtracting 45 from 54.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 15

Step 6:
15 can be fit into 91 6 times, resulting in a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 53136.0
If we take 90 away from 91, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
When dividing 10 by 15, we get 0 with a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 53136.0
Deduct 0 from 10 and we're left 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.

Let's proceed to step 8:
When dividing 100 by 15, we get 6 with a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 53136.06
Subtract 90 from 100 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 9:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 53136.066
The remainder is 10 after subtracting 90 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

After the division, we end up with 53136.066 and a remainder of 0.001.
