We divide 72147 by 15
The aim is to understand the frequency of 15 in 72147.

Moving on to step 1:
When dividing 7 by 15, we get 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 15

Let's proceed to step 2:
15 can be fit into 72 4 times, resulting in a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtracting 60 from 72 leaves us with 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 15

Advancing to step 3:
121 divided by 15 is 8 with a remainder of 1.
The next digit of our result is 8. 
Result so far: 48.0
If we take 120 away from 121, we end up with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 15

Let's proceed to step 4:
When dividing 14 by 15, we get 0 with a remainder of 14.
The number 0 becomes the next digit in our result. 
Result so far: 480.0
If we take 0 away from 14, we end up with 14.
Fetch the next digit (7) from the dividend, attach it to 14 and continue: 147 / 15

Going ahead to step 5:
The number 15 fits into 147 9 times, leaving a remainder of 12.
The number 9 becomes the next digit in our result. 
Result so far: 4809.0
The remainder is 12 after subtracting 135 from 147.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 6:
15 goes into 120 8 times with a remainder of 0.
The next digit of our result is 8. 
Result so far: 4809.8
Deduct 120 from 120 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
15 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 4809.8
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
0 divided by 15 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 4809.8
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 4809.8 with a remaining 0.0.
