We divide 204161 by 20
The aim is to understand the frequency of 20 in 204161.

Let's proceed to step 1:
The number 20 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 20

Going ahead to step 2:
If we divide 20 by 20, we get 1 and a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtracting 20 from 20 leaves us with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 20

On to step 3:
When dividing 4 by 20, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 10.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (1) of the dividend behind the 4 and repeat the process: 41 / 20

On to step 4:
When dividing 41 by 20, we get 2 with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 102.0
Subtract 40 from 41 to get 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 20

Step 5:
20 goes into 16 0 times with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 1020.0
If we subtract 0 from 16, we get 16.
Append the next digit (1) from the dividend to 16 and continue with: 161 / 20

Going ahead to step 6:
20 goes into 161 8 times with a remainder of 1.
The next digit of our result is 8. 
Result so far: 10208.0
If we subtract 160 from 161, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
20 goes into 10 0 times with a remainder of 10.
Use 0 as the next digit of our solution. 
Result so far: 10208.0
If we subtract 0 from 10, 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.

On to step 8:
20 goes into 100 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 10208.05
The remainder is 0 after subtracting 100 from 100.
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 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: 10208.05
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.

Let's proceed to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 10208.05
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.

The final result is 10208.05 with a remainder of 0.0.
