We're dividing 724215 by 20 
We're looking to find how many times 20 goes into 724215.

Let's proceed to step 1:
If we divide 7 by 20, we get 0 and a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Grab the next digit (2) from the dividend, add it to 7, then carry on: 72 / 20

Let's proceed to step 2:
If we divide 72 by 20, we get 3 and a remainder of 12.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtract 60 from 72 to get 12.
Take the next digit (4) from the dividend and append it to 12, then repeat: 124 / 20

Going ahead to step 3:
When dividing 124 by 20, we get 6 with a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 36.0
Subtracting 120 from 124 leaves us with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 20

Step 4:
When dividing 42 by 20, we get 2 with a remainder of 2.
The next digit of our result is 2. 
Result so far: 362.0
The remainder is 2 after subtracting 40 from 42.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 20

Step 5:
The number 20 fits into 21 1 times, leaving a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 3621.0
The remainder is 1 after subtracting 20 from 21.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 20

Moving on to step 6:
20 goes into 15 0 times with a remainder of 15.
The number 0 becomes the next digit in our result. 
Result so far: 36210.0
Subtract 0 from 15 to get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 7:
When dividing 150 by 20, we get 7 with a remainder of 10.
The number 7 becomes the next digit in our result. 
Result so far: 36210.7
Deduct 140 from 150 and we're left 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.

Step 8:
The number 20 fits into 100 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 36210.75
The remainder is 0 after subtracting 100 from 100.
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:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 36210.75
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.

Advancing to step 10:
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: 36210.75
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.

Our division results in 36210.75 with a remaining 0.0.
