Let's divide 142700 by 20
The aim is to understand the frequency of 20 in 142700.

Advancing to step 1:
20 goes into 1 0 times with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 20

Let's proceed to step 2:
When dividing 14 by 20, we get 0 with a remainder of 14.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 14 to get 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 20

Advancing to step 3:
20 goes into 142 7 times with a remainder of 2.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Subtracting 140 from 142 leaves us with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 20

Step 4:
If we divide 27 by 20, we get 1 and a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 71.0
Subtracting 20 from 27 leaves us with 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 20

Going ahead to step 5:
If we divide 70 by 20, we get 3 and a remainder of 10.
Write down 3 as next digit of the result. 
Result so far: 713.0
Deduct 60 from 70 and we're left with 10.
Grab the next digit (0) from the dividend, add it to 10, then carry on: 100 / 20

Moving on to step 6:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 7135.0
The remainder is 0 after subtracting 100 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 7:
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: 7135.0
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.

Moving on to step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 7135.0
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 outcome is 7135.0, with a leftover of 0.0.
