We look at the division of 947062 by 15 
The aim is to understand the frequency of 15 in 947062.

Advancing to step 1:
15 goes into 9 0 times with a remainder of 9.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 9 after subtracting 0 from 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 15

Step 2:
15 goes into 94 6 times with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we subtract 90 from 94, we get 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 15

On to step 3:
15 goes into 47 3 times with a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 63.0
Subtract 45 from 47 to get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 15

Going ahead to step 4:
When dividing 20 by 15, we get 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 631.0
Deduct 15 from 20 and we're left with 5.
Include the next digit (6) from the dividend after 5, then repeat: 56 / 15

Step 5:
When dividing 56 by 15, we get 3 with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 6313.0
If we take 45 away from 56, we end up with 11.
Bring next digit (2) of the dividend behind the 11 and repeat the process: 112 / 15

Going ahead to step 6:
15 can be fit into 112 7 times, resulting in a remainder of 7.
Write down 7 as next digit of the result. 
Result so far: 63137.0
Deduct 105 from 112 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
When dividing 70 by 15, we get 4 with a remainder of 10.
Write down 4 as next digit of the result. 
Result so far: 63137.4
If we subtract 60 from 70, we 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.

Moving on to step 8:
100 divided by 15 is 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 63137.46
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.

Advancing to step 9:
If we divide 100 by 15, we get 6 and a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 63137.466
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.

The final result is 63137.466 with a remainder of 0.001.
