We're dividing 969497 by 15 
The aim is to understand the frequency of 15 in 969497.

Going ahead to step 1:
9 divided by 15 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 9 and we're left with 9.
Include the next digit (6) from the dividend after 9, then repeat: 96 / 15

Step 2:
The number 15 fits into 96 6 times, leaving a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 90 from 96 and we're left with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 15

Going ahead to step 3:
When dividing 69 by 15, we get 4 with a remainder of 9.
Record the quotient 4 as the next digit in the result. 
Result so far: 64.0
Subtract 60 from 69 to get 9.
Fetch the next digit (4) from the dividend, attach it to 9 and continue: 94 / 15

Going ahead to step 4:
When dividing 94 by 15, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 646.0
The remainder is 4 after subtracting 90 from 94.
Fetch the next digit (9) from the dividend, attach it to 4 and continue: 49 / 15

Advancing to step 5:
15 goes into 49 3 times with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 6463.0
The remainder is 4 after subtracting 45 from 49.
Include the next digit (7) from the dividend after 4, then repeat: 47 / 15

Going ahead to step 6:
The number 15 fits into 47 3 times, leaving a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 64633.0
Subtracting 45 from 47 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 7:
15 goes into 20 1 times with a remainder of 5.
The next digit of our result is 1. 
Result so far: 64633.1
If we subtract 15 from 20, 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.

Step 8:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 64633.13
Subtract 45 from 50 to 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.

Step 9:
If we divide 50 by 15, we get 3 and a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 64633.133
Subtracting 45 from 50 leaves us 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.

The quotient of the division is 64633.133, and the remainder is 0.0005.
