We look at the division of 844018 by 15 
The aim is to understand the frequency of 15 in 844018.

Step 1:
8 divided by 15 is 0 with a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 15

Let's proceed to step 2:
If we divide 84 by 15, we get 5 and a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 5.0
The remainder is 9 after subtracting 75 from 84.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 15

Going ahead to step 3:
15 goes into 94 6 times with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 56.0
If we subtract 90 from 94, we get 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 15

Let's proceed to step 4:
If we divide 40 by 15, we get 2 and a remainder of 10.
Use 2 as the next digit of our solution. 
Result so far: 562.0
If we subtract 30 from 40, we get 10.
Grab the next digit (1) from the dividend, add it to 10, then carry on: 101 / 15

Advancing to step 5:
15 goes into 101 6 times with a remainder of 11.
Record the quotient 6 as the next digit in the result. 
Result so far: 5626.0
If we take 90 away from 101, we end up with 11.
Include the next digit (8) from the dividend after 11, then repeat: 118 / 15

On to step 6:
15 can be fit into 118 7 times, resulting in a remainder of 13.
The next digit of our result is 7. 
Result so far: 56267.0
The remainder is 13 after subtracting 105 from 118.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Going ahead to step 7:
If we divide 130 by 15, we get 8 and a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 56267.8
Subtract 120 from 130 to get 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:
100 divided by 15 is 6 with a remainder of 10.
The next digit of our result is 6. 
Result so far: 56267.86
Subtract 90 from 100 to get 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.
The next digit of our result is 6. 
Result so far: 56267.866
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.

Our division results in 56267.866 with a remaining 0.001.
