Let's divide 181941 by 15
The aim is to understand the frequency of 15 in 181941.

Going ahead to step 1:
If we divide 1 by 15, we get 0 and a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 15

Let's proceed to step 2:
15 can be fit into 18 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 15 from 18 and we're left with 3.
Include the next digit (1) from the dividend after 3, then repeat: 31 / 15

Moving on to step 3:
31 divided by 15 is 2 with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 12.0
If we subtract 30 from 31, we get 1.
Fetch the next digit (9) from the dividend, attach it to 1 and continue: 19 / 15

Going ahead to step 4:
If we divide 19 by 15, we get 1 and a remainder of 4.
The next digit of our result is 1. 
Result so far: 121.0
If we take 15 away from 19, we end up with 4.
Take the next digit (4) from the dividend and append it to 4, then repeat: 44 / 15

Let's proceed to step 5:
15 can be fit into 44 2 times, resulting in a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 1212.0
Subtracting 30 from 44 leaves us with 14.
Bring next digit (1) of the dividend behind the 14 and repeat the process: 141 / 15

Going ahead to step 6:
15 can be fit into 141 9 times, resulting in a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 12129.0
Deduct 135 from 141 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 7:
60 divided by 15 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 12129.4
Subtracting 60 from 60 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.

Let's proceed to step 8:
If we divide 0 by 15, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 12129.4
Deduct 0 from 0 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.

Let's proceed to step 9:
0 divided by 15 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 12129.4
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.

In conclusion, the division gives 12129.4 with a balance of 0.0.
