Let's divide 5711 by 20
The aim is to understand the frequency of 20 in 5711.

Advancing to step 1:
When dividing 5 by 20, we get 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 20

Going ahead to step 2:
20 can be fit into 57 2 times, resulting in a remainder of 17.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtracting 40 from 57 leaves us with 17.
Append the next digit (1) from the dividend to 17 and continue with: 171 / 20

Let's proceed to step 3:
171 divided by 20 is 8 with a remainder of 11.
Put 8 as the next digit of the answer. 
Result so far: 28.0
Deduct 160 from 171 and we're left with 11.
Take the next digit (1) from the dividend and append it to 11, then repeat: 111 / 20

On to step 4:
20 goes into 111 5 times with a remainder of 11.
Use 5 as the next digit of our solution. 
Result so far: 285.0
Deduct 100 from 111 and we're left with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Going ahead to step 5:
The number 20 fits into 110 5 times, leaving a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 285.5
If we take 100 away from 110, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 6:
When dividing 100 by 20, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 285.55
If we subtract 100 from 100, 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 quotient of the division is 285.55, and the remainder is 0.0.
