We look at the division of 784190 by 20 
We want to divide 784190 by 20.

On to step 1:
If we divide 7 by 20, we get 0 and a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Append the next digit (8) from the dividend to 7 and continue with: 78 / 20

Going ahead to step 2:
If we divide 78 by 20, we get 3 and a remainder of 18.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we subtract 60 from 78, we get 18.
Include the next digit (4) from the dividend after 18, then repeat: 184 / 20

Step 3:
If we divide 184 by 20, we get 9 and a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 39.0
If we take 180 away from 184, we end up with 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 20

Moving on to step 4:
41 divided by 20 is 2 with a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 392.0
Deduct 40 from 41 and we're left with 1.
Append the next digit (9) from the dividend to 1 and continue with: 19 / 20

Moving on to step 5:
20 can be fit into 19 0 times, resulting in a remainder of 19.
Use 0 as the next digit of our solution. 
Result so far: 3920.0
Deduct 0 from 19 and we're left with 19.
Grab the next digit (0) from the dividend, add it to 19, then carry on: 190 / 20

Going ahead to step 6:
The number 20 fits into 190 9 times, leaving a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 39209.0
If we take 180 away from 190, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 7:
When dividing 100 by 20, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 39209.5
If we take 100 away from 100, 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.

Going ahead to step 8:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 39209.5
Deduct 0 from 0 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.

Let's proceed to step 9:
The number 20 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 39209.5
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 39209.5 with a balance of 0.0.
