We're dividing 20405843 by 496 
Our goal is to divide 20405843 by 496.

Moving on to step 1:
If we divide 2 by 496, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 496

Step 2:
The number 496 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 20, we end up with 20.
Include the next digit (4) from the dividend after 20, then repeat: 204 / 496

On to step 3:
204 divided by 496 is 0 with a remainder of 204.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 204, we get 204.
Bring next digit (0) of the dividend behind the 204 and repeat the process: 2040 / 496

Going ahead to step 4:
496 can be fit into 2040 4 times, resulting in a remainder of 56.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 1984 from 2040 leaves us with 56.
Grab the next digit (5) from the dividend, add it to 56, then carry on: 565 / 496

On to step 5:
565 divided by 496 is 1 with a remainder of 69.
Record the quotient 1 as the next digit in the result. 
Result so far: 41.0
Subtracting 496 from 565 leaves us with 69.
Bring next digit (8) of the dividend behind the 69 and repeat the process: 698 / 496

Moving on to step 6:
When dividing 698 by 496, we get 1 with a remainder of 202.
Put 1 as the next digit of the answer. 
Result so far: 411.0
If we take 496 away from 698, we end up with 202.
Append the next digit (4) from the dividend to 202 and continue with: 2024 / 496

Going ahead to step 7:
496 can be fit into 2024 4 times, resulting in a remainder of 40.
Write down 4 as next digit of the result. 
Result so far: 4114.0
Subtracting 1984 from 2024 leaves us with 40.
Grab the next digit (3) from the dividend, add it to 40, then carry on: 403 / 496

Moving on to step 8:
When dividing 403 by 496, we get 0 with a remainder of 403.
Record the quotient 0 as the next digit in the result. 
Result so far: 41140.0
The remainder is 403 after subtracting 0 from 403.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Moving on to step 9:
If we divide 4030 by 496, we get 8 and a remainder of 62.
Use 8 as the next digit of our solution. 
Result so far: 41140.8
Subtracting 3968 from 4030 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 10:
When dividing 620 by 496, we get 1 with a remainder of 124.
Write down 1 as next digit of the result. 
Result so far: 41140.81
Subtracting 496 from 620 leaves us with 124.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1240, and continue the process.

Going ahead to step 11:
496 can be fit into 1240 2 times, resulting in a remainder of 248.
Write down 2 as next digit of the result. 
Result so far: 41140.812
Deduct 992 from 1240 and we're left with 248.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2480, and continue the process.

Advancing to step 12:
If we divide 2480 by 496, we get 5 and a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 41140.8125
Subtract 2480 from 2480 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.

Step 13:
496 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 41140.8125
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.

Let's proceed to step 14:
The number 496 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 41140.8125
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.

The final outcome is 41140.8125, with a leftover of 0.0.
