We look at the division of 402363 by 45 
Let's see how many times 45 fits into 402363.

Let's proceed to step 1:
If we divide 4 by 45, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Include the next digit (0) from the dividend after 4, then repeat: 40 / 45

Going ahead to step 2:
45 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 40 to get 40.
Grab the next digit (2) from the dividend, add it to 40, then carry on: 402 / 45

Going ahead to step 3:
45 can be fit into 402 8 times, resulting in a remainder of 42.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 360 from 402 leaves us with 42.
Take the next digit (3) from the dividend and append it to 42, then repeat: 423 / 45

Going ahead to step 4:
The number 45 fits into 423 9 times, leaving a remainder of 18.
Use 9 as the next digit of our solution. 
Result so far: 89.0
The remainder is 18 after subtracting 405 from 423.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 45

Moving on to step 5:
45 goes into 186 4 times with a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 894.0
If we subtract 180 from 186, we get 6.
Grab the next digit (3) from the dividend, add it to 6, then carry on: 63 / 45

Going ahead to step 6:
When dividing 63 by 45, we get 1 with a remainder of 18.
Use 1 as the next digit of our solution. 
Result so far: 8941.0
The remainder is 18 after subtracting 45 from 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
45 can be fit into 180 4 times, resulting in a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 8941.4
Subtracting 180 from 180 leaves us 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 8:
The number 45 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8941.4
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.

On to step 9:
45 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8941.4
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.

The final result is 8941.4 with a remainder of 0.0.
