178205 divided by 15 
The aim is to understand the frequency of 15 in 178205.

Advancing to step 1:
If we divide 1 by 15, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 15

Going ahead to step 2:
15 goes into 17 1 times with a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 2 after subtracting 15 from 17.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 15

On to step 3:
15 can be fit into 28 1 times, resulting in a remainder of 13.
Write down 1 as next digit of the result. 
Result so far: 11.0
Subtract 15 from 28 to get 13.
Append the next digit (2) from the dividend to 13 and continue with: 132 / 15

Advancing to step 4:
132 divided by 15 is 8 with a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 118.0
Deduct 120 from 132 and we're left with 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 15

Advancing to step 5:
If we divide 120 by 15, we get 8 and a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 1188.0
If we subtract 120 from 120, we get 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 15

Let's proceed to step 6:
15 can be fit into 5 0 times, resulting in a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 11880.0
Deduct 0 from 5 and we're left 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.

Moving on to step 7:
15 can be fit into 50 3 times, resulting in a remainder of 5.
The next digit of our result is 3. 
Result so far: 11880.3
Deduct 45 from 50 and we're left 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.

Advancing to step 8:
When dividing 50 by 15, we get 3 with a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 11880.33
If we subtract 45 from 50, 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.

The quotient of the division is 11880.33, and the remainder is 0.005.
