We divide 408277 by 20
We're looking to find how many times 20 goes into 408277.

Let's proceed to step 1:
20 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 20

Going ahead to step 2:
20 goes into 40 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 40 away from 40, we end up with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 20

On to step 3:
8 divided by 20 is 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 20.0
If we take 0 away from 8, we end up with 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 20

Step 4:
82 divided by 20 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 204.0
Subtracting 80 from 82 leaves us with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 20

Going ahead to step 5:
20 goes into 27 1 times with a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 2041.0
If we take 20 away from 27, we end up with 7.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 20

Going ahead to step 6:
20 can be fit into 77 3 times, resulting in a remainder of 17.
The next digit of our result is 3. 
Result so far: 20413.0
Subtracting 60 from 77 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
When dividing 170 by 20, we get 8 with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 20413.8
The remainder is 10 after subtracting 160 from 170.
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:
100 divided by 20 is 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 20413.85
If we take 100 away from 100, 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.

Going ahead to step 9:
0 divided by 20 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 20413.85
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.

Moving on to step 10:
When dividing 0 by 20, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20413.85
Deduct 0 from 0 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.

The quotient of the division is 20413.85, and the remainder is 0.0.
