Let's divide 132843 by 20
The aim is to understand the frequency of 20 in 132843.

Step 1:
20 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 20

Let's proceed to step 2:
20 can be fit into 13 0 times, resulting in a remainder of 13.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 13 and we're left with 13.
Include the next digit (2) from the dividend after 13, then repeat: 132 / 20

Advancing to step 3:
20 goes into 132 6 times with a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
Deduct 120 from 132 and we're left with 12.
Grab the next digit (8) from the dividend, add it to 12, then carry on: 128 / 20

Moving on to step 4:
When dividing 128 by 20, we get 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 66.0
If we take 120 away from 128, we end up with 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 20

Step 5:
When dividing 84 by 20, we get 4 with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 664.0
If we subtract 80 from 84, we get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 20

Step 6:
20 can be fit into 43 2 times, resulting in a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 6642.0
If we subtract 40 from 43, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
If we divide 30 by 20, we get 1 and a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 6642.1
If we subtract 20 from 30, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
20 goes into 100 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 6642.15
Deduct 100 from 100 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:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 6642.15
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.

Step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 6642.15
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.

The final outcome is 6642.15, with a leftover of 0.0.
