We divide 815595 by 45
We're looking to find how many times 45 goes into 815595.

Going ahead to 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
Subtract 0 from 8 to get 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 45

Moving on to step 2:
45 can be fit into 81 1 times, resulting in a remainder of 36.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 45 from 81 leaves us with 36.
Append the next digit (5) from the dividend to 36 and continue with: 365 / 45

On to step 3:
45 goes into 365 8 times with a remainder of 5.
Put 8 as the next digit of the answer. 
Result so far: 18.0
Subtract 360 from 365 to get 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 45

Moving on to step 4:
If we divide 55 by 45, we get 1 and a remainder of 10.
Use 1 as the next digit of our solution. 
Result so far: 181.0
Subtract 45 from 55 to get 10.
Include the next digit (9) from the dividend after 10, then repeat: 109 / 45

Going ahead to step 5:
If we divide 109 by 45, we get 2 and a remainder of 19.
The next digit of our result is 2. 
Result so far: 1812.0
Subtract 90 from 109 to get 19.
Take the next digit (5) from the dividend and append it to 19, then repeat: 195 / 45

Moving on to step 6:
195 divided by 45 is 4 with a remainder of 15.
Put 4 as the next digit of the answer. 
Result so far: 18124.0
Subtracting 180 from 195 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 7:
45 can be fit into 150 3 times, resulting in a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 18124.3
If we take 135 away from 150, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 8:
45 goes into 150 3 times with a remainder of 15.
Write down 3 as next digit of the result. 
Result so far: 18124.33
The remainder is 15 after subtracting 135 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

In conclusion, the division gives 18124.33 with a balance of 0.015.
