We look at the division of 667127 by 20 
The aim is to understand the frequency of 20 in 667127.

On to step 1:
The number 20 fits into 6 0 times, leaving a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 20

Moving on to step 2:
The number 20 fits into 66 3 times, leaving a remainder of 6.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 60 from 66 leaves us with 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 20

On to step 3:
20 can be fit into 67 3 times, resulting in a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 33.0
The remainder is 7 after subtracting 60 from 67.
Append the next digit (1) from the dividend to 7 and continue with: 71 / 20

Let's proceed to step 4:
The number 20 fits into 71 3 times, leaving a remainder of 11.
Write down 3 as next digit of the result. 
Result so far: 333.0
If we take 60 away from 71, we end up with 11.
Append the next digit (2) from the dividend to 11 and continue with: 112 / 20

Going ahead to step 5:
20 goes into 112 5 times with a remainder of 12.
Put 5 as the next digit of the answer. 
Result so far: 3335.0
The remainder is 12 after subtracting 100 from 112.
Take the next digit (7) from the dividend and append it to 12, then repeat: 127 / 20

Going ahead to step 6:
20 can be fit into 127 6 times, resulting in a remainder of 7.
The next digit of our result is 6. 
Result so far: 33356.0
Subtract 120 from 127 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 7:
The number 20 fits into 70 3 times, leaving a remainder of 10.
Use 3 as the next digit of our solution. 
Result so far: 33356.3
Subtracting 60 from 70 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 33356.35
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.

Advancing to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 33356.35
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.

Let's proceed to step 10:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 33356.35
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.

Our division results in 33356.35 with a remaining 0.0.
