403883 ÷ 20 
We want to figure out the number of times 403883 can be divided by 20.

Going ahead to step 1:
20 can be fit into 4 0 times, resulting in a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 20

Step 2:
The number 20 fits into 40 2 times, leaving a remainder of 0.
The next digit of our result is 2. 
Result so far: 2.0
If we take 40 away from 40, we end up with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 20

Moving on to step 3:
The number 20 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 20.0
If we take 0 away from 3, we end up with 3.
Grab the next digit (8) from the dividend, add it to 3, then carry on: 38 / 20

Let's proceed to step 4:
38 divided by 20 is 1 with a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 201.0
If we take 20 away from 38, we end up with 18.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 20

Advancing to step 5:
20 can be fit into 188 9 times, resulting in a remainder of 8.
The number 9 becomes the next digit in our result. 
Result so far: 2019.0
The remainder is 8 after subtracting 180 from 188.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 20

Moving on to step 6:
When dividing 83 by 20, we get 4 with a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 20194.0
If we take 80 away from 83, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
If we divide 30 by 20, we get 1 and a remainder of 10.
Record the quotient 1 as the next digit in the result. 
Result so far: 20194.1
The remainder is 10 after subtracting 20 from 30.
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: 20194.15
Deduct 100 from 100 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.

Advancing to step 9:
0 divided by 20 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 20194.15
The remainder is 0 after subtracting 0 from 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:
20 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 20194.15
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.

After the division, we end up with 20194.15 and a remainder of 0.0.
