728241 divided by 20 
We're looking to find how many times 20 goes into 728241.

On to step 1:
20 can be fit into 7 0 times, resulting in a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Append the next digit (2) from the dividend to 7 and continue with: 72 / 20

Step 2:
The number 20 fits into 72 3 times, leaving a remainder of 12.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 60 from 72 and we're left with 12.
Append the next digit (8) from the dividend to 12 and continue with: 128 / 20

Moving on to step 3:
20 goes into 128 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 36.0
If we subtract 120 from 128, we get 8.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 20

Going ahead to step 4:
20 goes into 82 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 364.0
Subtracting 80 from 82 leaves us with 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 20

Going ahead to step 5:
If we divide 24 by 20, we get 1 and a remainder of 4.
The next digit of our result is 1. 
Result so far: 3641.0
The remainder is 4 after subtracting 20 from 24.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 20

Advancing to step 6:
20 goes into 41 2 times with a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 36412.0
If we subtract 40 from 41, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
10 divided by 20 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 36412.0
If we take 0 away from 10, we end up 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.

Moving on to step 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 36412.05
Deduct 100 from 100 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.

Advancing to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 36412.05
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:
If we divide 0 by 20, we get 0 and a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 36412.05
If we take 0 away from 0, we end up 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.

Our division results in 36412.05 with a remaining 0.0.
