Let's divide 861363 by 45
We're looking to find how many times 45 goes into 861363.

Step 1:
The number 45 fits into 8 0 times, leaving a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 45

Step 2:
45 goes into 86 1 times with a remainder of 41.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 45 from 86, we get 41.
Take the next digit (1) from the dividend and append it to 41, then repeat: 411 / 45

On to step 3:
45 can be fit into 411 9 times, resulting in a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we subtract 405 from 411, we get 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 45

Moving on to step 4:
45 can be fit into 63 1 times, resulting in a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 191.0
Subtract 45 from 63 to get 18.
Bring next digit (6) of the dividend behind the 18 and repeat the process: 186 / 45

Going ahead to step 5:
45 goes into 186 4 times with a remainder of 6.
Put 4 as the next digit of the answer. 
Result so far: 1914.0
If we subtract 180 from 186, we get 6.
Take the next digit (3) from the dividend and append it to 6, then repeat: 63 / 45

Moving on 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: 19141.0
If we subtract 45 from 63, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 7:
180 divided by 45 is 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 19141.4
Subtract 180 from 180 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 8:
The number 45 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 19141.4
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
The number 45 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 19141.4
Subtracting 0 from 0 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.

In conclusion, the division gives 19141.4 with a balance of 0.0.
