Let's divide 863264 by 45
Let's see how many times 45 fits into 863264.

Going ahead to step 1:
The number 45 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Bring next digit (6) of the dividend behind the 8 and repeat the process: 86 / 45

Let's proceed to step 2:
86 divided by 45 is 1 with a remainder of 41.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 45 away from 86, we end up with 41.
Fetch the next digit (3) from the dividend, attach it to 41 and continue: 413 / 45

Moving on to step 3:
45 can be fit into 413 9 times, resulting in a remainder of 8.
Record the quotient 9 as the next digit in the result. 
Result so far: 19.0
Subtracting 405 from 413 leaves us with 8.
Fetch the next digit (2) from the dividend, attach it to 8 and continue: 82 / 45

On to step 4:
45 goes into 82 1 times with a remainder of 37.
Use 1 as the next digit of our solution. 
Result so far: 191.0
Deduct 45 from 82 and we're left with 37.
Bring next digit (6) of the dividend behind the 37 and repeat the process: 376 / 45

Going ahead to step 5:
The number 45 fits into 376 8 times, leaving a remainder of 16.
Record the quotient 8 as the next digit in the result. 
Result so far: 1918.0
If we subtract 360 from 376, we get 16.
Include the next digit (4) from the dividend after 16, then repeat: 164 / 45

On to step 6:
164 divided by 45 is 3 with a remainder of 29.
Use 3 as the next digit of our solution. 
Result so far: 19183.0
Subtracting 135 from 164 leaves us with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 7:
When dividing 290 by 45, we get 6 with a remainder of 20.
Use 6 as the next digit of our solution. 
Result so far: 19183.6
Subtract 270 from 290 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 8:
200 divided by 45 is 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 19183.64
If we subtract 180 from 200, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Step 9:
200 divided by 45 is 4 with a remainder of 20.
Use 4 as the next digit of our solution. 
Result so far: 19183.644
If we take 180 away from 200, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The quotient of the division is 19183.644, and the remainder is 0.002.
