409177 divided by 20 
Our goal is to divide 409177 by 20.

Moving on to step 1:
20 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 20

Let's proceed to step 2:
20 can be fit into 40 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtract 40 from 40 to get 0.
Bring next digit (9) of the dividend behind the 0 and repeat the process: 9 / 20

Advancing to step 3:
When dividing 9 by 20, we get 0 with a remainder of 9.
The next digit of our result is 0. 
Result so far: 20.0
Deduct 0 from 9 and we're left with 9.
Append the next digit (1) from the dividend to 9 and continue with: 91 / 20

Advancing to step 4:
91 divided by 20 is 4 with a remainder of 11.
The number 4 becomes the next digit in our result. 
Result so far: 204.0
If we subtract 80 from 91, we get 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 20

Advancing to step 5:
When dividing 117 by 20, we get 5 with a remainder of 17.
Write down 5 as next digit of the result. 
Result so far: 2045.0
Subtract 100 from 117 to get 17.
Take the next digit (7) from the dividend and append it to 17, then repeat: 177 / 20

Advancing to step 6:
The number 20 fits into 177 8 times, leaving a remainder of 17.
Use 8 as the next digit of our solution. 
Result so far: 20458.0
Deduct 160 from 177 and we're left 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:
170 divided by 20 is 8 with a remainder of 10.
Record the quotient 8 as the next digit in the result. 
Result so far: 20458.8
Subtracting 160 from 170 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
100 divided by 20 is 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 20458.85
Subtract 100 from 100 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.

Moving on to step 9:
If we divide 0 by 20, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 20458.85
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.

On to step 10:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 20458.85
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 quotient of the division is 20458.85, and the remainder is 0.0.
