We're dividing 852008 by 20 
The aim is to understand the frequency of 20 in 852008.

Let's proceed to step 1:
20 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 20

Let's proceed to step 2:
When dividing 85 by 20, we get 4 with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 80 from 85 leaves us with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 20

Moving on to step 3:
52 divided by 20 is 2 with a remainder of 12.
Use 2 as the next digit of our solution. 
Result so far: 42.0
Subtracting 40 from 52 leaves us with 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 20

On to step 4:
If we divide 120 by 20, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 426.0
Subtract 120 from 120 to get 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 20

Advancing to step 5:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 4260.0
The remainder is 0 after subtracting 0 from 0.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 20

Step 6:
When dividing 8 by 20, we get 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 42600.0
If we subtract 0 from 8, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 7:
20 can be fit into 80 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 42600.4
If we take 80 away from 80, 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.

Let's proceed to step 8:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 42600.4
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.

Advancing to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 42600.4
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 quotient of the division is 42600.4, and the remainder is 0.0.
