We're dividing 368303 by 45 
Let's see how many times 45 fits into 368303.

On to step 1:
The number 45 fits into 3 0 times, leaving a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 45

Step 2:
If we divide 36 by 45, we get 0 and a remainder of 36.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 36 after subtracting 0 from 36.
Grab the next digit (8) from the dividend, add it to 36, then carry on: 368 / 45

Advancing to step 3:
The number 45 fits into 368 8 times, leaving a remainder of 8.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 360 from 368 and we're left with 8.
Fetch the next digit (3) from the dividend, attach it to 8 and continue: 83 / 45

Step 4:
The number 45 fits into 83 1 times, leaving a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 81.0
If we take 45 away from 83, we end up with 38.
Grab the next digit (0) from the dividend, add it to 38, then carry on: 380 / 45

Advancing to step 5:
The number 45 fits into 380 8 times, leaving a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 818.0
The remainder is 20 after subtracting 360 from 380.
Bring next digit (3) of the dividend behind the 20 and repeat the process: 203 / 45

Step 6:
When dividing 203 by 45, we get 4 with a remainder of 23.
The number 4 becomes the next digit in our result. 
Result so far: 8184.0
If we take 180 away from 203, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 7:
45 can be fit into 230 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 8184.5
Subtracting 225 from 230 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.

Let's proceed to step 8:
45 can be fit into 50 1 times, resulting in a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 8184.51
Subtracting 45 from 50 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.

Step 9:
45 goes into 50 1 times with a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 8184.511
Subtract 45 from 50 to get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final result is 8184.511 with a remainder of 0.0005.
