We look at the division of 644034 by 20 
The aim is to understand the frequency of 20 in 644034.

Moving on to step 1:
When dividing 6 by 20, we get 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Bring next digit (4) of the dividend behind the 6 and repeat the process: 64 / 20

Let's proceed to step 2:
20 can be fit into 64 3 times, resulting in a remainder of 4.
The next digit of our result is 3. 
Result so far: 3.0
If we take 60 away from 64, we end up with 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 20

Step 3:
20 can be fit into 44 2 times, resulting in a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 32.0
Subtracting 40 from 44 leaves us with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 20

Moving on to step 4:
If we divide 40 by 20, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 322.0
If we take 40 away from 40, we end up with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 20

Step 5:
20 goes into 3 0 times with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 3220.0
The remainder is 3 after subtracting 0 from 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 20

Step 6:
When dividing 34 by 20, we get 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 32201.0
If we take 20 away from 34, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
If we divide 140 by 20, we get 7 and a remainder of 0.
Write down 7 as next digit of the result. 
Result so far: 32201.7
Deduct 140 from 140 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.

On to step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 32201.7
Subtract 0 from 0 to 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.

Moving on to step 9:
20 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 32201.7
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 32201.7 with a remaining 0.0.
