100608 divided by 20 
The aim is to understand the frequency of 20 in 100608.

Going ahead to step 1:
1 divided by 20 is 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 20

Going ahead to step 2:
20 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 10 to get 10.
Append the next digit (0) from the dividend to 10 and continue with: 100 / 20

On to step 3:
20 goes into 100 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 100 from 100 leaves us with 0.
Grab the next digit (6) from the dividend, add it to 0, then carry on: 6 / 20

Moving on to step 4:
6 divided by 20 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 50.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (0) from the dividend, add it to 6, then carry on: 60 / 20

On to step 5:
If we divide 60 by 20, we get 3 and a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 503.0
If we subtract 60 from 60, we get 0.
Fetch the next digit (8) from the dividend, attach it to 0 and continue: 8 / 20

Going ahead to step 6:
8 divided by 20 is 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 5030.0
Deduct 0 from 8 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 7:
The number 20 fits into 80 4 times, leaving a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 5030.4
Subtract 80 from 80 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.

Step 8:
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: 5030.4
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.

Let's proceed to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 5030.4
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.

The final result is 5030.4 with a remainder of 0.0.
