We divide 478985 by 15
The aim is to understand the frequency of 15 in 478985.

Going ahead to step 1:
When dividing 4 by 15, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (7) from the dividend, attach it to 4 and continue: 47 / 15

Let's proceed to step 2:
When dividing 47 by 15, we get 3 with a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 45 from 47 leaves us with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 15

Let's proceed to step 3:
If we divide 28 by 15, we get 1 and a remainder of 13.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
If we take 15 away from 28, we end up with 13.
Append the next digit (9) from the dividend to 13 and continue with: 139 / 15

Let's proceed to step 4:
When dividing 139 by 15, we get 9 with a remainder of 4.
The next digit of our result is 9. 
Result so far: 319.0
If we subtract 135 from 139, we get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 15

Let's proceed to step 5:
15 can be fit into 48 3 times, resulting in a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 3193.0
Subtracting 45 from 48 leaves us with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 15

Advancing to step 6:
When dividing 35 by 15, we get 2 with a remainder of 5.
Record the quotient 2 as the next digit in the result. 
Result so far: 31932.0
If we take 30 away from 35, we end up 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 7:
15 can be fit into 50 3 times, resulting in a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 31932.3
The remainder is 5 after subtracting 45 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Let's proceed to step 8:
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: 31932.33
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.

In conclusion, the division gives 31932.33 with a balance of 0.005.
