201803 ÷ 4 
Our goal is to divide 201803 by 4.

Step 1:
The number 4 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 4

Going ahead to step 2:
4 goes into 20 5 times with a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 20 from 20, we get 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 4

On to step 3:
1 divided by 4 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 50.0
Subtract 0 from 1 to get 1.
Append the next digit (8) from the dividend to 1 and continue with: 18 / 4

Going ahead to step 4:
18 divided by 4 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 504.0
Subtract 16 from 18 to get 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 4

Moving on to step 5:
If we divide 20 by 4, we get 5 and a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 5045.0
Subtract 20 from 20 to get 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 4

Going ahead to step 6:
When dividing 3 by 4, we get 0 with a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 50450.0
If we take 0 away from 3, 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.

On to step 7:
The number 4 fits into 30 7 times, leaving a remainder of 2.
Write down 7 as next digit of the result. 
Result so far: 50450.7
Subtract 28 from 30 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 8:
The number 4 fits into 20 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 50450.75
Deduct 20 from 20 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.

Step 9:
When dividing 0 by 4, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 50450.75
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.

Step 10:
When dividing 0 by 4, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 50450.75
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.

The final outcome is 50450.75, with a leftover of 0.0.
