We're dividing 607165 by 15 
The aim is to understand the frequency of 15 in 607165.

Step 1:
15 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 15

Let's proceed to step 2:
When dividing 60 by 15, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 60 from 60 and we're left with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 15

Advancing to step 3:
15 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 40.0
The remainder is 7 after subtracting 0 from 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 15

Advancing to step 4:
15 goes into 71 4 times with a remainder of 11.
Use 4 as the next digit of our solution. 
Result so far: 404.0
If we take 60 away from 71, we end up with 11.
Append the next digit (6) from the dividend to 11 and continue with: 116 / 15

On to step 5:
116 divided by 15 is 7 with a remainder of 11.
Write down 7 as next digit of the result. 
Result so far: 4047.0
If we subtract 105 from 116, we get 11.
Append the next digit (5) from the dividend to 11 and continue with: 115 / 15

Going ahead to step 6:
The number 15 fits into 115 7 times, leaving a remainder of 10.
Write down 7 as next digit of the result. 
Result so far: 40477.0
Deduct 105 from 115 and we're left 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.

Advancing to step 7:
100 divided by 15 is 6 with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 40477.6
If we subtract 90 from 100, 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.

Going ahead to step 8:
15 can be fit into 100 6 times, resulting in a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 40477.66
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 40477.66 with a remainder of 0.01.
