721348 ÷ 20 
We're looking to find how many times 20 goes into 721348.

Moving on to step 1:
When dividing 7 by 20, we get 0 with a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 20

Let's proceed to step 2:
If we divide 72 by 20, we get 3 and a remainder of 12.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 60 from 72 to get 12.
Append the next digit (1) from the dividend to 12 and continue with: 121 / 20

Let's proceed to step 3:
If we divide 121 by 20, we get 6 and a remainder of 1.
Write down 6 as next digit of the result. 
Result so far: 36.0
The remainder is 1 after subtracting 120 from 121.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 20

Advancing to step 4:
If we divide 13 by 20, we get 0 and a remainder of 13.
The number 0 becomes the next digit in our result. 
Result so far: 360.0
Subtracting 0 from 13 leaves us with 13.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 20

Let's proceed to step 5:
20 goes into 134 6 times with a remainder of 14.
Use 6 as the next digit of our solution. 
Result so far: 3606.0
Subtracting 120 from 134 leaves us with 14.
Fetch the next digit (8) from the dividend, attach it to 14 and continue: 148 / 20

Let's proceed to step 6:
148 divided by 20 is 7 with a remainder of 8.
The number 7 becomes the next digit in our result. 
Result so far: 36067.0
If we take 140 away from 148, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 7:
When dividing 80 by 20, we get 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 36067.4
If we take 80 away from 80, 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.

Advancing to step 8:
0 divided by 20 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 36067.4
The remainder is 0 after subtracting 0 from 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:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 36067.4
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.

In conclusion, the division gives 36067.4 with a balance of 0.0.
