411545 divided by 20 
Our goal is to divide 411545 by 20.

Advancing to step 1:
When dividing 4 by 20, we get 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (1) from the dividend to 4 and continue with: 41 / 20

Step 2:
20 can be fit into 41 2 times, resulting in a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 40 away from 41, we end up with 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 20

Moving on to step 3:
20 can be fit into 11 0 times, resulting in a remainder of 11.
The number 0 becomes the next digit in our result. 
Result so far: 20.0
The remainder is 11 after subtracting 0 from 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 20

Step 4:
When dividing 115 by 20, we get 5 with a remainder of 15.
The next digit of our result is 5. 
Result so far: 205.0
If we subtract 100 from 115, we get 15.
Take the next digit (4) from the dividend and append it to 15, then repeat: 154 / 20

On to step 5:
20 goes into 154 7 times with a remainder of 14.
Record the quotient 7 as the next digit in the result. 
Result so far: 2057.0
The remainder is 14 after subtracting 140 from 154.
Append the next digit (5) from the dividend to 14 and continue with: 145 / 20

Advancing to step 6:
When dividing 145 by 20, we get 7 with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 20577.0
Subtracting 140 from 145 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
50 divided by 20 is 2 with a remainder of 10.
The number 2 becomes the next digit in our result. 
Result so far: 20577.2
The remainder is 10 after subtracting 40 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
20 can be fit into 100 5 times, resulting in a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 20577.25
The remainder is 0 after subtracting 100 from 100.
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:
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: 20577.25
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:
0 divided by 20 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20577.25
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.

Our division results in 20577.25 with a remaining 0.0.
