We look at the division of 27242302 by 20 
The aim is to understand the frequency of 20 in 27242302.

On to step 1:
20 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 20

Step 2:
20 can be fit into 27 1 times, resulting in a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Deduct 20 from 27 and we're left with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 20

Moving on to step 3:
20 can be fit into 72 3 times, resulting in a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 60 away from 72, we end up with 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 20

Step 4:
When dividing 124 by 20, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 136.0
Subtract 120 from 124 to get 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 20

Let's proceed to step 5:
The number 20 fits into 42 2 times, leaving a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 1362.0
Subtract 40 from 42 to get 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 20

Moving on to step 6:
If we divide 23 by 20, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 13621.0
If we take 20 away from 23, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 20

Advancing to step 7:
20 can be fit into 30 1 times, resulting in a remainder of 10.
The next digit of our result is 1. 
Result so far: 136211.0
Subtract 20 from 30 to get 10.
Grab the next digit (2) from the dividend, add it to 10, then carry on: 102 / 20

Step 8:
20 can be fit into 102 5 times, resulting in a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 1362115.0
Subtracting 100 from 102 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
The number 20 fits into 20 1 times, leaving a remainder of 0.
The next digit of our result is 1. 
Result so far: 1362115.1
The remainder is 0 after subtracting 20 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 1362115.1
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 11:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1362115.1
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.

Our division results in 1362115.1 with a remaining 0.0.
