712248 ÷ 20 
The aim is to understand the frequency of 20 in 712248.

Advancing to step 1:
If we divide 7 by 20, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Grab the next digit (1) from the dividend, add it to 7, then carry on: 71 / 20

Let's proceed to step 2:
71 divided by 20 is 3 with a remainder of 11.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 60 from 71 and we're left with 11.
Fetch the next digit (2) from the dividend, attach it to 11 and continue: 112 / 20

Going ahead to step 3:
20 can be fit into 112 5 times, resulting in a remainder of 12.
The next digit of our result is 5. 
Result so far: 35.0
If we take 100 away from 112, we end up with 12.
Include the next digit (2) from the dividend after 12, then repeat: 122 / 20

Step 4:
20 goes into 122 6 times with a remainder of 2.
Put 6 as the next digit of the answer. 
Result so far: 356.0
If we take 120 away from 122, we end up with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 20

Let's proceed to step 5:
When dividing 24 by 20, we get 1 with a remainder of 4.
Put 1 as the next digit of the answer. 
Result so far: 3561.0
Deduct 20 from 24 and we're left with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 20

On to step 6:
20 goes into 48 2 times with a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 35612.0
If we take 40 away from 48, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
20 can be fit into 80 4 times, resulting in a remainder of 0.
The next digit of our result is 4. 
Result so far: 35612.4
Subtract 80 from 80 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:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 35612.4
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.

Let's proceed to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 35612.4
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 quotient of the division is 35612.4, and the remainder is 0.0.
