720943 divided by 20 
We're looking to find how many times 20 goes into 720943.

Moving on 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
Subtracting 0 from 7 leaves us with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 20

Step 2:
The number 20 fits into 72 3 times, leaving a remainder of 12.
The next digit of our result is 3. 
Result so far: 3.0
If we subtract 60 from 72, we get 12.
Append the next digit (0) from the dividend to 12 and continue with: 120 / 20

On to step 3:
When dividing 120 by 20, we get 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
If we take 120 away from 120, we end up with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 20

Advancing to step 4:
The number 20 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 360.0
Subtracting 0 from 9 leaves us with 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 20

Let's proceed to step 5:
20 can be fit into 94 4 times, resulting in a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 3604.0
Deduct 80 from 94 and we're left with 14.
Take the next digit (3) from the dividend and append it to 14, then repeat: 143 / 20

Let's proceed to step 6:
If we divide 143 by 20, we get 7 and a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 36047.0
Subtract 140 from 143 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 7:
If we divide 30 by 20, we get 1 and a remainder of 10.
Put 1 as the next digit of the answer. 
Result so far: 36047.1
If we subtract 20 from 30, 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.
Record the quotient 5 as the next digit in the result. 
Result so far: 36047.15
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:
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: 36047.15
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.

Let's proceed to step 10:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 36047.15
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.

The final outcome is 36047.15, with a leftover of 0.0.
