We divide 479051 by 15
The aim is to understand the frequency of 15 in 479051.

Let's proceed to step 1:
If we divide 4 by 15, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 15

Step 2:
15 goes into 47 3 times with a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
The remainder is 2 after subtracting 45 from 47.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 15

On to step 3:
If we divide 29 by 15, we get 1 and a remainder of 14.
Write down 1 as next digit of the result. 
Result so far: 31.0
Subtracting 15 from 29 leaves us with 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 15

Moving on to step 4:
15 goes into 140 9 times with a remainder of 5.
The next digit of our result is 9. 
Result so far: 319.0
If we take 135 away from 140, we end up with 5.
Append the next digit (5) from the dividend to 5 and continue with: 55 / 15

Going ahead to step 5:
15 goes into 55 3 times with a remainder of 10.
The next digit of our result is 3. 
Result so far: 3193.0
The remainder is 10 after subtracting 45 from 55.
Fetch the next digit (1) from the dividend, attach it to 10 and continue: 101 / 15

Let's proceed to step 6:
If we divide 101 by 15, we get 6 and a remainder of 11.
The next digit of our result is 6. 
Result so far: 31936.0
Deduct 90 from 101 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Step 7:
When dividing 110 by 15, we get 7 with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 31936.7
Subtract 105 from 110 to 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.

Going ahead to step 8:
The number 15 fits into 50 3 times, leaving a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 31936.73
Subtracting 45 from 50 leaves us 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.

Going ahead to step 9:
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: 31936.733
If we take 45 away from 50, 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.

The final result is 31936.733 with a remainder of 0.0005.
