We're dividing 815294 by 45 
Our goal is to divide 815294 by 45.

Advancing to step 1:
45 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (1) from the dividend, add it to 8, then carry on: 81 / 45

Advancing to step 2:
If we divide 81 by 45, we get 1 and a remainder of 36.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we take 45 away from 81, we end up with 36.
Fetch the next digit (5) from the dividend, attach it to 36 and continue: 365 / 45

Going ahead to step 3:
45 goes into 365 8 times with a remainder of 5.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Deduct 360 from 365 and we're left with 5.
Bring next digit (2) of the dividend behind the 5 and repeat the process: 52 / 45

Let's proceed to step 4:
45 goes into 52 1 times with a remainder of 7.
The number 1 becomes the next digit in our result. 
Result so far: 181.0
If we subtract 45 from 52, we get 7.
Append the next digit (9) from the dividend to 7 and continue with: 79 / 45

Step 5:
45 can be fit into 79 1 times, resulting in a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 1811.0
Deduct 45 from 79 and we're left with 34.
Grab the next digit (4) from the dividend, add it to 34, then carry on: 344 / 45

Advancing to step 6:
The number 45 fits into 344 7 times, leaving a remainder of 29.
The next digit of our result is 7. 
Result so far: 18117.0
If we subtract 315 from 344, we get 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

Going ahead to step 7:
If we divide 290 by 45, we get 6 and a remainder of 20.
Record the quotient 6 as the next digit in the result. 
Result so far: 18117.6
If we subtract 270 from 290, 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.

Going ahead to step 8:
The number 45 fits into 200 4 times, leaving a remainder of 20.
The number 4 becomes the next digit in our result. 
Result so far: 18117.64
The remainder is 20 after subtracting 180 from 200.
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.
Write down 4 as next digit of the result. 
Result so far: 18117.644
Deduct 180 from 200 and we're left 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.

In conclusion, the division gives 18117.644 with a balance of 0.002.
