707969 divided by 15 
The aim is to understand the frequency of 15 in 707969.

Advancing to step 1:
15 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (0) from the dividend, attach it to 7 and continue: 70 / 15

Going ahead to step 2:
70 divided by 15 is 4 with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtracting 60 from 70 leaves us with 10.
Take the next digit (7) from the dividend and append it to 10, then repeat: 107 / 15

Step 3:
107 divided by 15 is 7 with a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 47.0
Subtracting 105 from 107 leaves us with 2.
Bring next digit (9) of the dividend behind the 2 and repeat the process: 29 / 15

Going ahead to step 4:
15 goes into 29 1 times with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 471.0
Deduct 15 from 29 and we're left with 14.
Bring next digit (6) of the dividend behind the 14 and repeat the process: 146 / 15

Going ahead to step 5:
15 can be fit into 146 9 times, resulting in a remainder of 11.
Put 9 as the next digit of the answer. 
Result so far: 4719.0
The remainder is 11 after subtracting 135 from 146.
Append the next digit (9) from the dividend to 11 and continue with: 119 / 15

Let's proceed to step 6:
119 divided by 15 is 7 with a remainder of 14.
Write down 7 as next digit of the result. 
Result so far: 47197.0
If we take 105 away from 119, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
140 divided by 15 is 9 with a remainder of 5.
The next digit of our result is 9. 
Result so far: 47197.9
If we take 135 away from 140, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 8:
When dividing 50 by 15, we get 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 47197.93
If we take 45 away from 50, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 9:
15 goes into 50 3 times with a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 47197.933
If we subtract 45 from 50, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 47197.933 with a remainder of 0.0005.
