Let's divide 667847 by 15
The aim is to understand the frequency of 15 in 667847.

Step 1:
15 can be fit into 6 0 times, resulting in a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 15

Moving on to step 2:
The number 15 fits into 66 4 times, leaving a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we subtract 60 from 66, we get 6.
Grab the next digit (7) from the dividend, add it to 6, then carry on: 67 / 15

Going ahead to step 3:
When dividing 67 by 15, we get 4 with a remainder of 7.
Write down 4 as next digit of the result. 
Result so far: 44.0
Deduct 60 from 67 and we're left with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 15

Let's proceed to step 4:
15 can be fit into 78 5 times, resulting in a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 445.0
If we take 75 away from 78, we end up with 3.
Bring next digit (4) of the dividend behind the 3 and repeat the process: 34 / 15

Advancing to step 5:
The number 15 fits into 34 2 times, leaving a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 4452.0
If we take 30 away from 34, we end up with 4.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 15

Moving on to step 6:
15 can be fit into 47 3 times, resulting in a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 44523.0
Deduct 45 from 47 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 7:
20 divided by 15 is 1 with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 44523.1
If we take 15 away from 20, 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.

Going ahead to step 8:
When dividing 50 by 15, we get 3 with a remainder of 5.
The next digit of our result is 3. 
Result so far: 44523.13
Subtract 45 from 50 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.

Moving on to step 9:
When dividing 50 by 15, we get 3 with a remainder of 5.
Write down 3 as next digit of the result. 
Result so far: 44523.133
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.

Our division results in 44523.133 with a remaining 0.0005.
