We're dividing 789420 by 20 
Let's see how many times 20 fits into 789420.

Moving on to step 1:
20 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Take the next digit (8) from the dividend and append it to 7, then repeat: 78 / 20

Let's proceed to step 2:
20 can be fit into 78 3 times, resulting in a remainder of 18.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 60 from 78 leaves us with 18.
Fetch the next digit (9) from the dividend, attach it to 18 and continue: 189 / 20

Going ahead to step 3:
20 can be fit into 189 9 times, resulting in a remainder of 9.
The next digit of our result is 9. 
Result so far: 39.0
If we take 180 away from 189, we end up with 9.
Take the next digit (4) from the dividend and append it to 9, then repeat: 94 / 20

On to step 4:
20 goes into 94 4 times with a remainder of 14.
Put 4 as the next digit of the answer. 
Result so far: 394.0
The remainder is 14 after subtracting 80 from 94.
Append the next digit (2) from the dividend to 14 and continue with: 142 / 20

Moving on to step 5:
142 divided by 20 is 7 with a remainder of 2.
Use 7 as the next digit of our solution. 
Result so far: 3947.0
Subtract 140 from 142 to get 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 20

Step 6:
20 goes into 20 1 times with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 39471.0
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.

Moving on to step 7:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 39471.0
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.

Moving on to step 8:
When dividing 0 by 20, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 39471.0
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.

In conclusion, the division gives 39471.0 with a balance of 0.0.
