790795 divided by 15 
The aim is to understand the frequency of 15 in 790795.

On to step 1:
7 divided by 15 is 0 with a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 7, we get 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.
Use 5 as the next digit of our solution. 
Result so far: 5.0
Subtracting 75 from 79 leaves us with 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 15

Step 3:
40 divided by 15 is 2 with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 52.0
Subtracting 30 from 40 leaves us with 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 15

Going ahead to step 4:
15 goes into 107 7 times with a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 527.0
If we subtract 105 from 107, we get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 15

Going ahead to step 5:
When dividing 29 by 15, we get 1 with a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 5271.0
Deduct 15 from 29 and we're left with 14.
Append the next digit (5) from the dividend to 14 and continue with: 145 / 15

Moving on to step 6:
When dividing 145 by 15, we get 9 with a remainder of 10.
Write down 9 as next digit of the result. 
Result so far: 52719.0
Subtracting 135 from 145 leaves us 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.

On to step 7:
When dividing 100 by 15, we get 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 52719.6
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.

On to step 8:
If we divide 100 by 15, we get 6 and a remainder of 10.
Put 6 as the next digit of the answer. 
Result so far: 52719.66
Subtracting 90 from 100 leaves us 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.

In conclusion, the division gives 52719.66 with a balance of 0.01.
