We look at the division of 684829 by 20 
The aim is to understand the frequency of 20 in 684829.

Moving on to step 1:
20 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 20

On 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
Subtracting 60 from 68 leaves us with 8.
Include the next digit (4) from the dividend after 8, then repeat: 84 / 20

Advancing to step 3:
84 divided by 20 is 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 34.0
If we subtract 80 from 84, we get 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 20

On to step 4:
When dividing 48 by 20, we get 2 with a remainder of 8.
The next digit of our result is 2. 
Result so far: 342.0
The remainder is 8 after subtracting 40 from 48.
Include the next digit (2) from the dividend after 8, then repeat: 82 / 20

Going ahead to step 5:
20 goes into 82 4 times with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 3424.0
Deduct 80 from 82 and we're left with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 20

Step 6:
The number 20 fits into 29 1 times, leaving a remainder of 9.
Use 1 as the next digit of our solution. 
Result so far: 34241.0
The remainder is 9 after subtracting 20 from 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
20 can be fit into 90 4 times, resulting in a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 34241.4
Subtract 80 from 90 to get 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:
20 can be fit into 100 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 34241.45
Subtract 100 from 100 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.

On to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 34241.45
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 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 34241.45
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 34241.45 with a remaining 0.0.
