40846 divided by 20 
Our goal is to divide 40846 by 20.

Let's proceed to step 1:
The number 20 fits into 4 0 times, leaving a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 20

Moving on to step 2:
20 can be fit into 40 2 times, resulting in a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 40 from 40 and we're left with 0.
Take the next digit (8) from the dividend and append it to 0, then repeat: 8 / 20

Step 3:
20 can be fit into 8 0 times, resulting in a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we subtract 0 from 8, we get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 20

Let's proceed to step 4:
84 divided by 20 is 4 with a remainder of 4.
Use 4 as the next digit of our solution. 
Result so far: 204.0
If we subtract 80 from 84, we get 4.
Append the next digit (6) from the dividend to 4 and continue with: 46 / 20

Advancing to step 5:
20 goes into 46 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 2042.0
Subtracting 40 from 46 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 6:
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: 2042.3
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.

Let's proceed to step 7:
0 divided by 20 is 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2042.3
Subtract 0 from 0 to 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.

On to step 8:
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: 2042.3
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.

The final outcome is 2042.3, with a leftover of 0.0.
