We're dividing 729940 by 20 
We want to figure out the number of times 729940 can be divided by 20.

Advancing to step 1:
7 divided by 20 is 0 with a remainder of 7.
The next digit of our result is 0. 
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:
20 can be fit into 72 3 times, resulting in a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 60 from 72 leaves us with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 20

Let's proceed to step 3:
When dividing 129 by 20, we get 6 with a remainder of 9.
Record the quotient 6 as the next digit in the result. 
Result so far: 36.0
The remainder is 9 after subtracting 120 from 129.
Include the next digit (9) from the dividend after 9, then repeat: 99 / 20

On to step 4:
99 divided by 20 is 4 with a remainder of 19.
Use 4 as the next digit of our solution. 
Result so far: 364.0
If we subtract 80 from 99, we get 19.
Bring next digit (4) of the dividend behind the 19 and repeat the process: 194 / 20

Going ahead to step 5:
194 divided by 20 is 9 with a remainder of 14.
Put 9 as the next digit of the answer. 
Result so far: 3649.0
If we take 180 away from 194, we end up with 14.
Grab the next digit (0) from the dividend, add it to 14, then carry on: 140 / 20

Going ahead to step 6:
When dividing 140 by 20, we get 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 36497.0
Subtracting 140 from 140 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.

Step 7:
When dividing 0 by 20, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 36497.0
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.

Step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 36497.0
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 36497.0 with a remaining 0.0.
