We're dividing 604867 by 15 
The aim is to understand the frequency of 15 in 604867.

Moving on to step 1:
6 divided by 15 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 15

Advancing to step 2:
15 can be fit into 60 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 4.0
If we subtract 60 from 60, we get 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 15

Let's proceed to step 3:
If we divide 4 by 15, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 40.0
If we take 0 away from 4, we end up with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 15

Step 4:
48 divided by 15 is 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 403.0
Subtracting 45 from 48 leaves us with 3.
Append the next digit (6) from the dividend to 3 and continue with: 36 / 15

Moving on to step 5:
When dividing 36 by 15, we get 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 4032.0
Subtract 30 from 36 to get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 15

Let's proceed to step 6:
67 divided by 15 is 4 with a remainder of 7.
Put 4 as the next digit of the answer. 
Result so far: 40324.0
If we subtract 60 from 67, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Let's proceed to step 7:
If we divide 70 by 15, we get 4 and a remainder of 10.
The next digit of our result is 4. 
Result so far: 40324.4
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.
Record the quotient 6 as the next digit in the result. 
Result so far: 40324.46
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.

Advancing to step 9:
The number 15 fits into 100 6 times, leaving a remainder of 10.
Record the quotient 6 as the next digit in the result. 
Result so far: 40324.466
Deduct 90 from 100 and we're left 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 40324.466 and a remainder of 0.001.
