We're dividing 683011 by 15 
The aim is to understand the frequency of 15 in 683011.

On to step 1:
When dividing 6 by 15, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 15

Advancing to step 2:
68 divided by 15 is 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 60 from 68, we get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 15

Step 3:
15 goes into 83 5 times with a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 45.0
If we take 75 away from 83, we end up with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 15

Going ahead to step 4:
The number 15 fits into 80 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 455.0
The remainder is 5 after subtracting 75 from 80.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 15

Step 5:
15 can be fit into 51 3 times, resulting in a remainder of 6.
The next digit of our result is 3. 
Result so far: 4553.0
If we take 45 away from 51, we end up with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 15

Going ahead to step 6:
When dividing 61 by 15, we get 4 with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 45534.0
If we take 60 away from 61, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
15 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 45534.0
Deduct 0 from 10 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.

On to step 8:
100 divided by 15 is 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 45534.06
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.

On to step 9:
15 can be fit into 100 6 times, resulting in a remainder of 10.
The next digit of our result is 6. 
Result so far: 45534.066
If we take 90 away from 100, we end up 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.

The final result is 45534.066 with a remainder of 0.001.
