We divide 724355 by 20
The aim is to understand the frequency of 20 in 724355.

Advancing to step 1:
20 goes into 7 0 times with 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.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 20

Moving on to step 2:
20 goes into 72 3 times with a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 3.0
If we subtract 60 from 72, we get 12.
Grab the next digit (4) from the dividend, add it to 12, then carry on: 124 / 20

Step 3:
20 can be fit into 124 6 times, resulting in a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 36.0
If we subtract 120 from 124, we get 4.
Bring next digit (3) of the dividend behind the 4 and repeat the process: 43 / 20

Step 4:
When dividing 43 by 20, we get 2 with a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 362.0
Deduct 40 from 43 and we're left with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 20

Going ahead to step 5:
20 goes into 35 1 times with a remainder of 15.
The number 1 becomes the next digit in our result. 
Result so far: 3621.0
If we take 20 away from 35, we end up with 15.
Grab the next digit (5) from the dividend, add it to 15, then carry on: 155 / 20

Moving on to step 6:
20 can be fit into 155 7 times, resulting in a remainder of 15.
The number 7 becomes the next digit in our result. 
Result so far: 36217.0
If we take 140 away from 155, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 7:
When dividing 150 by 20, we get 7 with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 36217.7
If we subtract 140 from 150, we get 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 8:
If we divide 100 by 20, we get 5 and a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 36217.75
Subtract 100 from 100 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 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 36217.75
Subtracting 0 from 0 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.

Moving on to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 36217.75
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.

In conclusion, the division gives 36217.75 with a balance of 0.0.
