203702 ÷ 20 
The aim is to understand the frequency of 20 in 203702.

Step 1:
20 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 20

Moving on to step 2:
20 can be fit into 20 1 times, resulting in a remainder of 0.
The next digit of our result is 1. 
Result so far: 1.0
If we take 20 away from 20, we end up with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 20

Let's proceed to step 3:
When dividing 3 by 20, we get 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we subtract 0 from 3, we get 3.
Include the next digit (7) from the dividend after 3, then repeat: 37 / 20

Let's proceed to step 4:
If we divide 37 by 20, we get 1 and a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
If we subtract 20 from 37, we get 17.
Bring next digit (0) of the dividend behind the 17 and repeat the process: 170 / 20

Step 5:
20 can be fit into 170 8 times, resulting in a remainder of 10.
Put 8 as the next digit of the answer. 
Result so far: 1018.0
Subtract 160 from 170 to get 10.
Append the next digit (2) from the dividend to 10 and continue with: 102 / 20

Going ahead to step 6:
When dividing 102 by 20, we get 5 with a remainder of 2.
Record the quotient 5 as the next digit in the result. 
Result so far: 10185.0
Subtracting 100 from 102 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
20 divided by 20 is 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 10185.1
Subtract 20 from 20 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.

Going ahead to step 8:
20 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 10185.1
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.

Step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10185.1
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.

The quotient of the division is 10185.1, and the remainder is 0.0.
