We look at the division of 610846 by 20 
The aim is to understand the frequency of 20 in 610846.

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
If we take 0 away from 6, we end up with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 20

Moving on to step 2:
The number 20 fits into 61 3 times, leaving a remainder of 1.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 60 from 61 and we're left with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 20

Advancing to step 3:
20 goes into 10 0 times with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 30.0
Deduct 0 from 10 and we're left with 10.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 20

Step 4:
20 goes into 108 5 times with a remainder of 8.
Use 5 as the next digit of our solution. 
Result so far: 305.0
Deduct 100 from 108 and we're left with 8.
Append the next digit (4) from the dividend to 8 and continue with: 84 / 20

Moving on to step 5:
If we divide 84 by 20, we get 4 and a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 3054.0
Subtract 80 from 84 to get 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 20

Let's proceed to step 6:
If we divide 46 by 20, we get 2 and a remainder of 6.
The next digit of our result is 2. 
Result so far: 30542.0
Subtract 40 from 46 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
If we divide 60 by 20, we get 3 and a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 30542.3
Subtracting 60 from 60 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.

Moving on to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 30542.3
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.

Let's proceed to 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: 30542.3
If we take 0 away from 0, we end up 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 30542.3 with a remaining 0.0.
