721942 divided by 20 
We want to divide 721942 by 20.

Advancing to step 1:
20 can be fit into 7 0 times, resulting in 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.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 20

Step 2:
20 can be fit into 72 3 times, resulting in a remainder of 12.
Put 3 as the next digit of the answer. 
Result so far: 3.0
Deduct 60 from 72 and we're left with 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 20

Let's proceed to step 3:
20 can be fit into 121 6 times, resulting in a remainder of 1.
The next digit of our result is 6. 
Result so far: 36.0
The remainder is 1 after subtracting 120 from 121.
Grab the next digit (9) from the dividend, add it to 1, then carry on: 19 / 20

Advancing to step 4:
20 goes into 19 0 times with a remainder of 19.
Put 0 as the next digit of the answer. 
Result so far: 360.0
Subtract 0 from 19 to get 19.
Include the next digit (4) from the dividend after 19, then repeat: 194 / 20

Going ahead to step 5:
If we divide 194 by 20, we get 9 and a remainder of 14.
Write down 9 as next digit of the result. 
Result so far: 3609.0
Subtracting 180 from 194 leaves us with 14.
Take the next digit (2) from the dividend and append it to 14, then repeat: 142 / 20

Going ahead to step 6:
20 can be fit into 142 7 times, resulting in a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 36097.0
Subtract 140 from 142 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
20 divided by 20 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 36097.1
The remainder is 0 after subtracting 20 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
If we divide 0 by 20, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 36097.1
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.

On to step 9:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 36097.1
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.

The quotient of the division is 36097.1, and the remainder is 0.0.
