We look at the division of 781846 by 20 
We want to divide 781846 by 20.

Going ahead to step 1:
If we divide 7 by 20, we get 0 and a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Grab the next digit (8) from the dividend, add it to 7, then carry on: 78 / 20

Moving on 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
Deduct 60 from 78 and we're left with 18.
Bring next digit (1) of the dividend behind the 18 and repeat the process: 181 / 20

Moving on to step 3:
20 can be fit into 181 9 times, resulting in a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Subtract 180 from 181 to get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 20

Step 4:
18 divided by 20 is 0 with a remainder of 18.
The next digit of our result is 0. 
Result so far: 390.0
If we subtract 0 from 18, we get 18.
Fetch the next digit (4) from the dividend, attach it to 18 and continue: 184 / 20

Let's proceed to step 5:
If we divide 184 by 20, we get 9 and a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 3909.0
The remainder is 4 after subtracting 180 from 184.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 20

Let's proceed to step 6:
46 divided by 20 is 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 39092.0
Subtract 40 from 46 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
20 can be fit into 60 3 times, resulting in a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 39092.3
The remainder is 0 after subtracting 60 from 60.
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:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 39092.3
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.

Advancing to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 39092.3
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.

After the division, we end up with 39092.3 and a remainder of 0.0.
