682243 divided by 20 
The aim is to understand the frequency of 20 in 682243.

Step 1:
If we divide 6 by 20, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (8) from the dividend to 6 and continue with: 68 / 20

Let's proceed to step 2:
20 can be fit into 68 3 times, resulting in a remainder of 8.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
The remainder is 8 after subtracting 60 from 68.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 20

On to step 3:
20 can be fit into 82 4 times, resulting in a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 34.0
If we subtract 80 from 82, we get 2.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 20

Moving on to step 4:
The number 20 fits into 22 1 times, leaving a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 341.0
If we subtract 20 from 22, we get 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 20

Step 5:
20 goes into 24 1 times with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 3411.0
Deduct 20 from 24 and we're left with 4.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 20

Moving on to step 6:
If we divide 43 by 20, we get 2 and a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 34112.0
If we subtract 40 from 43, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 7:
The number 20 fits into 30 1 times, leaving a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 34112.1
If we subtract 20 from 30, we 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.

Let's proceed to step 8:
When dividing 100 by 20, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 34112.15
Deduct 100 from 100 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.

Step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 34112.15
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.

On to step 10:
0 divided by 20 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 34112.15
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.

Our division results in 34112.15 with a remaining 0.0.
