We're dividing 140542 by 20 
The aim is to understand the frequency of 20 in 140542.

Moving on 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
If we subtract 0 from 1, we get 1.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 20

Step 2:
If we divide 14 by 20, we get 0 and a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 14 after subtracting 0 from 14.
Fetch the next digit (0) from the dividend, attach it to 14 and continue: 140 / 20

Step 3:
20 goes into 140 7 times with a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 7.0
Subtract 140 from 140 to get 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 20

Going ahead to step 4:
When dividing 5 by 20, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 70.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 20

Let's proceed to step 5:
When dividing 54 by 20, we get 2 with a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 702.0
Subtracting 40 from 54 leaves us with 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 20

Let's proceed to step 6:
20 goes into 142 7 times with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 7027.0
If we subtract 140 from 142, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
When dividing 20 by 20, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 7027.1
If we take 20 away from 20, 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.

Step 8:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 7027.1
If we subtract 0 from 0, we 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.

Going ahead to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 7027.1
The remainder is 0 after subtracting 0 from 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 7027.1 with a balance of 0.0.
