We're dividing 23481 by 15 
The aim is to understand the frequency of 15 in 23481.

Moving on to step 1:
When dividing 2 by 15, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 15

Moving on to step 2:
When dividing 23 by 15, we get 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 15 away from 23, we end up with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 15

Going ahead to step 3:
If we divide 84 by 15, we get 5 and a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 15.0
If we take 75 away from 84, we end up with 9.
Bring next digit (8) of the dividend behind the 9 and repeat the process: 98 / 15

Step 4:
15 can be fit into 98 6 times, resulting in a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 156.0
Subtract 90 from 98 to get 8.
Bring next digit (1) of the dividend behind the 8 and repeat the process: 81 / 15

Going ahead to step 5:
If we divide 81 by 15, we get 5 and a remainder of 6.
Put 5 as the next digit of the answer. 
Result so far: 1565.0
Subtract 75 from 81 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 6:
The number 15 fits into 60 4 times, leaving a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 1565.4
Deduct 60 from 60 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.

Advancing to step 7:
15 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1565.4
If we take 0 away from 0, we end up 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.

Going ahead to step 8:
15 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1565.4
If we take 0 away from 0, we end up 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.

The final result is 1565.4 with a remainder of 0.0.
