905647 divided by 15 
The aim is to understand the frequency of 15 in 905647.

Let's proceed to step 1:
15 goes into 9 0 times with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (0) from the dividend to 9 and continue with: 90 / 15

On to step 2:
15 goes into 90 6 times with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 90 from 90 and we're left with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 15

Going ahead to step 3:
15 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 60.0
If we subtract 0 from 5, we get 5.
Append the next digit (6) from the dividend to 5 and continue with: 56 / 15

Let's proceed to step 4:
When dividing 56 by 15, we get 3 with a remainder of 11.
The next digit of our result is 3. 
Result so far: 603.0
Deduct 45 from 56 and we're left with 11.
Append the next digit (4) from the dividend to 11 and continue with: 114 / 15

Going ahead to step 5:
When dividing 114 by 15, we get 7 with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 6037.0
Subtract 105 from 114 to get 9.
Include the next digit (7) from the dividend after 9, then repeat: 97 / 15

Moving on to step 6:
97 divided by 15 is 6 with a remainder of 7.
The next digit of our result is 6. 
Result so far: 60376.0
If we take 90 away from 97, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
If we divide 70 by 15, we get 4 and a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 60376.4
If we take 60 away from 70, 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 8:
15 goes into 100 6 times with a remainder of 10.
Use 6 as the next digit of our solution. 
Result so far: 60376.46
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.

Moving on to step 9:
15 goes into 100 6 times with a remainder of 10.
Write down 6 as next digit of the result. 
Result so far: 60376.466
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 60376.466 and a remainder of 0.001.
