407282 ÷ 20 
Let's see how many times 20 fits into 407282.

Let's proceed to step 1:
If we divide 4 by 20, we get 0 and a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (0) from the dividend, add it to 4, then carry on: 40 / 20

Moving on to step 2:
The number 20 fits into 40 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 40 away from 40, we end up with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 20

On to step 3:
The number 20 fits into 7 0 times, leaving a remainder of 7.
The next digit of our result is 0. 
Result so far: 20.0
Subtracting 0 from 7 leaves us with 7.
Fetch the next digit (2) from the dividend, attach it to 7 and continue: 72 / 20

Going ahead to step 4:
72 divided by 20 is 3 with a remainder of 12.
Write down 3 as next digit of the result. 
Result so far: 203.0
If we subtract 60 from 72, we get 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 20

Step 5:
If we divide 128 by 20, we get 6 and a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 2036.0
Subtract 120 from 128 to get 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 20

Let's proceed to step 6:
82 divided by 20 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 20364.0
Subtracting 80 from 82 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Going ahead to step 7:
When dividing 20 by 20, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 20364.1
Deduct 20 from 20 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.

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: 20364.1
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.

Advancing to step 9:
When dividing 0 by 20, we get 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 20364.1
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 20364.1, with a leftover of 0.0.
