Let's divide 391841 by 20
Our goal is to divide 391841 by 20.

Advancing to step 1:
20 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 20

Going ahead to step 2:
20 can be fit into 39 1 times, resulting in a remainder of 19.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 19 after subtracting 20 from 39.
Take the next digit (1) from the dividend and append it to 19, then repeat: 191 / 20

On to step 3:
If we divide 191 by 20, we get 9 and a remainder of 11.
Use 9 as the next digit of our solution. 
Result so far: 19.0
The remainder is 11 after subtracting 180 from 191.
Append the next digit (8) from the dividend to 11 and continue with: 118 / 20

Let's proceed to step 4:
The number 20 fits into 118 5 times, leaving a remainder of 18.
Write down 5 as next digit of the result. 
Result so far: 195.0
Deduct 100 from 118 and we're left with 18.
Grab the next digit (4) from the dividend, add it to 18, then carry on: 184 / 20

Let's proceed to step 5:
The number 20 fits into 184 9 times, leaving a remainder of 4.
The next digit of our result is 9. 
Result so far: 1959.0
Deduct 180 from 184 and we're left with 4.
Grab the next digit (1) from the dividend, add it to 4, then carry on: 41 / 20

Step 6:
20 goes into 41 2 times with a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 19592.0
Subtract 40 from 41 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 7:
20 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 19592.0
The remainder is 10 after subtracting 0 from 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:
When dividing 100 by 20, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 19592.05
The remainder is 0 after subtracting 100 from 100.
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 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 19592.05
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.

Going ahead to step 10:
The number 20 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 19592.05
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.

In conclusion, the division gives 19592.05 with a balance of 0.0.
