Let's divide 855363 by 45
We're looking to find how many times 45 goes into 855363.

Let's proceed to step 1:
When dividing 8 by 45, we get 0 with a remainder of 8.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Fetch the next digit (5) from the dividend, attach it to 8 and continue: 85 / 45

Let's proceed to step 2:
85 divided by 45 is 1 with a remainder of 40.
The next digit of our result is 1. 
Result so far: 1.0
If we take 45 away from 85, we end up with 40.
Take the next digit (5) from the dividend and append it to 40, then repeat: 405 / 45

Going ahead to step 3:
45 can be fit into 405 9 times, resulting in a remainder of 0.
The next digit of our result is 9. 
Result so far: 19.0
If we take 405 away from 405, we end up with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 45

Going ahead to step 4:
45 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 190.0
Subtract 0 from 3 to get 3.
Include the next digit (6) from the dividend after 3, then repeat: 36 / 45

Step 5:
45 goes into 36 0 times with a remainder of 36.
Record the quotient 0 as the next digit in the result. 
Result so far: 1900.0
If we take 0 away from 36, we end up with 36.
Include the next digit (3) from the dividend after 36, then repeat: 363 / 45

Going ahead to step 6:
When dividing 363 by 45, we get 8 with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 19008.0
The remainder is 3 after subtracting 360 from 363.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
45 can be fit into 30 0 times, resulting in a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 19008.0
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Step 8:
45 goes into 300 6 times with a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 19008.06
Subtracting 270 from 300 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
45 goes into 300 6 times with a remainder of 30.
The next digit of our result is 6. 
Result so far: 19008.066
Subtract 270 from 300 to get 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Our division results in 19008.066 with a remaining 0.003.
