799260 ÷ 15 
The aim is to understand the frequency of 15 in 799260.

Step 1:
The number 15 fits into 7 0 times, leaving a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 15

Moving on to step 2:
If we divide 79 by 15, we get 5 and a remainder of 4.
The next digit of our result is 5. 
Result so far: 5.0
Deduct 75 from 79 and we're left with 4.
Grab the next digit (9) from the dividend, add it to 4, then carry on: 49 / 15

Let's proceed to step 3:
The number 15 fits into 49 3 times, leaving a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 53.0
Subtracting 45 from 49 leaves us with 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 15

Advancing to step 4:
42 divided by 15 is 2 with a remainder of 12.
The next digit of our result is 2. 
Result so far: 532.0
The remainder is 12 after subtracting 30 from 42.
Take the next digit (6) from the dividend and append it to 12, then repeat: 126 / 15

Moving on to step 5:
When dividing 126 by 15, we get 8 with a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 5328.0
If we take 120 away from 126, we end up with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 15

Moving on to step 6:
60 divided by 15 is 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 53284.0
Deduct 60 from 60 and we're left 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.

Moving on to step 7:
0 divided by 15 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 53284.0
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.

Advancing to step 8:
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: 53284.0
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.

Our division results in 53284.0 with a remaining 0.0.
