Let's divide 856204 by 15
The aim is to understand the frequency of 15 in 856204.

Advancing to step 1:
15 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Append the next digit (5) from the dividend to 8 and continue with: 85 / 15

On to step 2:
15 goes into 85 5 times with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 75 away from 85, we end up with 10.
Grab the next digit (6) from the dividend, add it to 10, then carry on: 106 / 15

On to step 3:
If we divide 106 by 15, we get 7 and a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
Deduct 105 from 106 and we're left with 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 15

On to step 4:
When dividing 12 by 15, we get 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 570.0
If we take 0 away from 12, we end up with 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 15

On to step 5:
When dividing 120 by 15, we get 8 with a remainder of 0.
The next digit of our result is 8. 
Result so far: 5708.0
Subtracting 120 from 120 leaves us with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 15

Step 6:
15 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 57080.0
Subtracting 0 from 4 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 7:
15 goes into 40 2 times with a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 57080.2
If we take 30 away from 40, 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.

Let's proceed to step 8:
When dividing 100 by 15, we get 6 with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 57080.26
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.

Moving on to step 9:
If we divide 100 by 15, we get 6 and a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 57080.266
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.

After the division, we end up with 57080.266 and a remainder of 0.001.
