720141 ÷ 20 
Our goal is to divide 720141 by 20.

Step 1:
7 divided by 20 is 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (2) from the dividend after 7, then repeat: 72 / 20

Moving on to step 2:
If we divide 72 by 20, we get 3 and a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 3.0
If we subtract 60 from 72, we get 12.
Grab the next digit (0) from the dividend, add it to 12, then carry on: 120 / 20

Moving on to step 3:
If we divide 120 by 20, we get 6 and a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
If we subtract 120 from 120, we get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 20

Going ahead to step 4:
If we divide 1 by 20, we get 0 and a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 360.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (4) from the dividend and append it to 1, then repeat: 14 / 20

Going ahead to step 5:
20 can be fit into 14 0 times, resulting in a remainder of 14.
Record the quotient 0 as the next digit in the result. 
Result so far: 3600.0
If we take 0 away from 14, we end up with 14.
Include the next digit (1) from the dividend after 14, then repeat: 141 / 20

On to step 6:
20 goes into 141 7 times with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 36007.0
Deduct 140 from 141 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
When dividing 10 by 20, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 36007.0
If we subtract 0 from 10, 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:
20 goes into 100 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 36007.05
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:
When dividing 0 by 20, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 36007.05
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.

Advancing to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 36007.05
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 36007.05 with a remaining 0.0.
