129516 divided by 20 
The aim is to understand the frequency of 20 in 129516.

Going ahead to step 1:
20 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Include the next digit (2) from the dividend after 1, then repeat: 12 / 20

Moving on to step 2:
12 divided by 20 is 0 with a remainder of 12.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 12 leaves us with 12.
Take the next digit (9) from the dividend and append it to 12, then repeat: 129 / 20

Advancing to step 3:
129 divided by 20 is 6 with a remainder of 9.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we subtract 120 from 129, we get 9.
Fetch the next digit (5) from the dividend, attach it to 9 and continue: 95 / 20

On to step 4:
When dividing 95 by 20, we get 4 with a remainder of 15.
The next digit of our result is 4. 
Result so far: 64.0
If we take 80 away from 95, we end up with 15.
Include the next digit (1) from the dividend after 15, then repeat: 151 / 20

Advancing to step 5:
The number 20 fits into 151 7 times, leaving a remainder of 11.
Record the quotient 7 as the next digit in the result. 
Result so far: 647.0
Subtract 140 from 151 to get 11.
Bring next digit (6) of the dividend behind the 11 and repeat the process: 116 / 20

Let's proceed to step 6:
When dividing 116 by 20, we get 5 with a remainder of 16.
The number 5 becomes the next digit in our result. 
Result so far: 6475.0
If we take 100 away from 116, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
If we divide 160 by 20, we get 8 and a remainder of 0.
The next digit of our result is 8. 
Result so far: 6475.8
Subtract 160 from 160 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.

On to step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 6475.8
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.

Let's proceed to step 9:
20 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: 6475.8
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.

In conclusion, the division gives 6475.8 with a balance of 0.0.
