Let's divide 375803 by 18
Let's see how many times 18 fits into 375803.

Step 1:
18 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 18

Step 2:
18 can be fit into 37 2 times, resulting in a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Subtracting 36 from 37 leaves us with 1.
Fetch the next digit (5) from the dividend, attach it to 1 and continue: 15 / 18

Moving on to step 3:
If we divide 15 by 18, we get 0 and a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 20.0
Subtract 0 from 15 to get 15.
Fetch the next digit (8) from the dividend, attach it to 15 and continue: 158 / 18

On to step 4:
If we divide 158 by 18, we get 8 and a remainder of 14.
Put 8 as the next digit of the answer. 
Result so far: 208.0
The remainder is 14 after subtracting 144 from 158.
Append the next digit (0) from the dividend to 14 and continue with: 140 / 18

Step 5:
18 can be fit into 140 7 times, resulting in a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 2087.0
If we take 126 away from 140, we end up with 14.
Include the next digit (3) from the dividend after 14, then repeat: 143 / 18

Going ahead to step 6:
The number 18 fits into 143 7 times, leaving a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 20877.0
The remainder is 17 after subtracting 126 from 143.
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:
When dividing 170 by 18, we get 9 with a remainder of 8.
The next digit of our result is 9. 
Result so far: 20877.9
The remainder is 8 after subtracting 162 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
18 can be fit into 80 4 times, resulting in a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 20877.94
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 9:
If we divide 80 by 18, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 20877.944
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 20877.944, and the remainder is 0.0008.
