We look at the division of 62921986 by 20 
The aim is to understand the frequency of 20 in 62921986.

On to step 1:
20 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 20

Let's proceed to step 2:
The number 20 fits into 62 3 times, leaving a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Subtracting 60 from 62 leaves us with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 20

Going ahead to step 3:
20 goes into 29 1 times with a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 31.0
Subtract 20 from 29 to get 9.
Take the next digit (2) from the dividend and append it to 9, then repeat: 92 / 20

Let's proceed to step 4:
If we divide 92 by 20, we get 4 and a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 314.0
Deduct 80 from 92 and we're left with 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 20

Let's proceed to step 5:
When dividing 121 by 20, we get 6 with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 3146.0
If we subtract 120 from 121, we get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 20

Moving on to step 6:
20 can be fit into 19 0 times, resulting in a remainder of 19.
The number 0 becomes the next digit in our result. 
Result so far: 31460.0
Deduct 0 from 19 and we're left with 19.
Include the next digit (8) from the dividend after 19, then repeat: 198 / 20

Advancing to step 7:
198 divided by 20 is 9 with a remainder of 18.
Write down 9 as next digit of the result. 
Result so far: 314609.0
Subtracting 180 from 198 leaves us with 18.
Fetch the next digit (6) from the dividend, attach it to 18 and continue: 186 / 20

Moving on to step 8:
If we divide 186 by 20, we get 9 and a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 3146099.0
Subtracting 180 from 186 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 9:
60 divided by 20 is 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 3146099.3
If we take 60 away from 60, 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 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3146099.3
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.

Going ahead to step 11:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 3146099.3
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.

Our division results in 3146099.3 with a remaining 0.0.
