We look at the division of 702720 by 20 
We want to divide 702720 by 20.

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
Subtracting 0 from 7 leaves us with 7.
Take the next digit (0) from the dividend and append it to 7, then repeat: 70 / 20

On to step 2:
20 goes into 70 3 times with a remainder of 10.
Put 3 as the next digit of the answer. 
Result so far: 3.0
The remainder is 10 after subtracting 60 from 70.
Fetch the next digit (2) from the dividend, attach it to 10 and continue: 102 / 20

Step 3:
If we divide 102 by 20, we get 5 and a remainder of 2.
The number 5 becomes the next digit in our result. 
Result so far: 35.0
If we take 100 away from 102, we end up with 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 20

Let's proceed to step 4:
When dividing 27 by 20, we get 1 with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 351.0
Subtract 20 from 27 to get 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 20

Going ahead to step 5:
72 divided by 20 is 3 with a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 3513.0
If we take 60 away from 72, we end up with 12.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 20

Step 6:
If we divide 120 by 20, we get 6 and a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 35136.0
If we subtract 120 from 120, 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.

On to step 7:
20 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 35136.0
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.

Moving on to step 8:
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: 35136.0
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 35136.0 with a remaining 0.0.
