Let's divide 743504 by 20
The aim is to understand the frequency of 20 in 743504.

Step 1:
When dividing 7 by 20, we get 0 with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Fetch the next digit (4) from the dividend, attach it to 7 and continue: 74 / 20

Advancing to step 2:
74 divided by 20 is 3 with a remainder of 14.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we take 60 away from 74, we end up with 14.
Bring next digit (3) of the dividend behind the 14 and repeat the process: 143 / 20

On to step 3:
20 can be fit into 143 7 times, resulting in a remainder of 3.
The number 7 becomes the next digit in our result. 
Result so far: 37.0
Subtract 140 from 143 to get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 20

Let's proceed to step 4:
35 divided by 20 is 1 with a remainder of 15.
Put 1 as the next digit of the answer. 
Result so far: 371.0
Deduct 20 from 35 and we're left with 15.
Bring next digit (0) of the dividend behind the 15 and repeat the process: 150 / 20

Step 5:
20 can be fit into 150 7 times, resulting in a remainder of 10.
Use 7 as the next digit of our solution. 
Result so far: 3717.0
If we take 140 away from 150, we end up with 10.
Bring next digit (4) of the dividend behind the 10 and repeat the process: 104 / 20

Going ahead to step 6:
20 goes into 104 5 times with a remainder of 4.
Use 5 as the next digit of our solution. 
Result so far: 37175.0
The remainder is 4 after subtracting 100 from 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
When dividing 40 by 20, we get 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 37175.2
The remainder is 0 after subtracting 40 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 8:
20 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 37175.2
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.

Let's proceed to step 9:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 37175.2
If we subtract 0 from 0, 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.

In conclusion, the division gives 37175.2 with a balance of 0.0.
