419321 ÷ 20 
Let's see how many times 20 fits into 419321.

Going ahead to step 1:
If we divide 4 by 20, we get 0 and a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 20

Going ahead to step 2:
20 goes into 41 2 times with a remainder of 1.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 40 from 41, we get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 20

Step 3:
19 divided by 20 is 0 with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 20.0
Deduct 0 from 19 and we're left with 19.
Append the next digit (3) from the dividend to 19 and continue with: 193 / 20

Advancing to step 4:
20 goes into 193 9 times with a remainder of 13.
The next digit of our result is 9. 
Result so far: 209.0
Subtracting 180 from 193 leaves us with 13.
Take the next digit (2) from the dividend and append it to 13, then repeat: 132 / 20

Going ahead to step 5:
If we divide 132 by 20, we get 6 and a remainder of 12.
The number 6 becomes the next digit in our result. 
Result so far: 2096.0
If we take 120 away from 132, we end up with 12.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 20

Moving on to step 6:
If we divide 121 by 20, we get 6 and a remainder of 1.
Put 6 as the next digit of the answer. 
Result so far: 20966.0
Subtract 120 from 121 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
10 divided by 20 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 20966.0
The remainder is 10 after subtracting 0 from 10.
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:
20 can be fit into 100 5 times, resulting in a remainder of 0.
The next digit of our result is 5. 
Result so far: 20966.05
If we subtract 100 from 100, 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.

Step 9:
20 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20966.05
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.

Let's proceed 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: 20966.05
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.

Our division results in 20966.05 with a remaining 0.0.
