We divide 68484 by 20
The aim is to understand the frequency of 20 in 68484.

Step 1:
When dividing 6 by 20, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 20

Going ahead to step 2:
If we divide 68 by 20, we get 3 and a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Subtract 60 from 68 to get 8.
Fetch the next digit (4) from the dividend, attach it to 8 and continue: 84 / 20

Moving on to step 3:
The number 20 fits into 84 4 times, leaving a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 34.0
If we take 80 away from 84, we end up with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 20

Let's proceed to step 4:
20 goes into 48 2 times with a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 342.0
If we subtract 40 from 48, we get 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 20

Step 5:
The number 20 fits into 84 4 times, leaving a remainder of 4.
The next digit of our result is 4. 
Result so far: 3424.0
If we take 80 away from 84, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 6:
If we divide 40 by 20, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 3424.2
Deduct 40 from 40 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.

Going ahead 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: 3424.2
If we subtract 0 from 0, we 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.

Advancing to step 8:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 3424.2
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.

The final result is 3424.2 with a remainder of 0.0.
