We look at the division of 303863 by 45 
We want to figure out the number of times 303863 can be divided by 45.

Going ahead to step 1:
3 divided by 45 is 0 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.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 45

Let's proceed to step 2:
45 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 30 to get 30.
Fetch the next digit (3) from the dividend, attach it to 30 and continue: 303 / 45

Going ahead to step 3:
303 divided by 45 is 6 with a remainder of 33.
The next digit of our result is 6. 
Result so far: 6.0
Deduct 270 from 303 and we're left with 33.
Append the next digit (8) from the dividend to 33 and continue with: 338 / 45

Let's proceed to step 4:
The number 45 fits into 338 7 times, leaving a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 67.0
Deduct 315 from 338 and we're left with 23.
Take the next digit (6) from the dividend and append it to 23, then repeat: 236 / 45

Let's proceed to step 5:
The number 45 fits into 236 5 times, leaving a remainder of 11.
The number 5 becomes the next digit in our result. 
Result so far: 675.0
If we subtract 225 from 236, we get 11.
Include the next digit (3) from the dividend after 11, then repeat: 113 / 45

Advancing to step 6:
If we divide 113 by 45, we get 2 and a remainder of 23.
Record the quotient 2 as the next digit in the result. 
Result so far: 6752.0
Deduct 90 from 113 and we're left 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.

Let's proceed to step 7:
45 goes into 230 5 times with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 6752.5
Deduct 225 from 230 and we're left 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.

Going ahead to step 8:
If we divide 50 by 45, we get 1 and a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 6752.51
If we subtract 45 from 50, we 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.

Moving on to step 9:
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: 6752.511
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 quotient of the division is 6752.511, and the remainder is 0.0005.
