Let's divide 10618 by 20
The aim is to understand the frequency of 20 in 10618.

Let's proceed to step 1:
When dividing 1 by 20, we get 0 with a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (0) from the dividend, add it to 1, then carry on: 10 / 20

On to step 2:
If we divide 10 by 20, we get 0 and a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 10 leaves us with 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 20

Moving on to step 3:
20 goes into 106 5 times with a remainder of 6.
The next digit of our result is 5. 
Result so far: 5.0
If we take 100 away from 106, we end up with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 20

Advancing to step 4:
20 can be fit into 61 3 times, resulting in a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 53.0
Subtract 60 from 61 to get 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 20

Let's proceed to step 5:
The number 20 fits into 18 0 times, leaving a remainder of 18.
Record the quotient 0 as the next digit in the result. 
Result so far: 530.0
Deduct 0 from 18 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 6:
The number 20 fits into 180 9 times, leaving a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 530.9
Subtracting 180 from 180 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 7:
If we divide 0 by 20, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 530.9
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.

Moving on to step 8:
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: 530.9
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.

The final result is 530.9 with a remainder of 0.0.
