We're dividing 816204 by 45 
Let's see how many times 45 fits into 816204.

Let's proceed 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
Deduct 0 from 8 and we're left with 8.
Take the next digit (1) from the dividend and append it to 8, then repeat: 81 / 45

On to step 2:
81 divided by 45 is 1 with a remainder of 36.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 45 from 81 to get 36.
Grab the next digit (6) from the dividend, add it to 36, then carry on: 366 / 45

Step 3:
If we divide 366 by 45, we get 8 and a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 18.0
Deduct 360 from 366 and we're left with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 45

Moving on to step 4:
The number 45 fits into 62 1 times, leaving a remainder of 17.
Record the quotient 1 as the next digit in the result. 
Result so far: 181.0
Deduct 45 from 62 and we're left with 17.
Take the next digit (0) from the dividend and append it to 17, then repeat: 170 / 45

Step 5:
If we divide 170 by 45, we get 3 and a remainder of 35.
Record the quotient 3 as the next digit in the result. 
Result so far: 1813.0
Subtracting 135 from 170 leaves us with 35.
Append the next digit (4) from the dividend to 35 and continue with: 354 / 45

Let's proceed to step 6:
The number 45 fits into 354 7 times, leaving a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 18137.0
If we subtract 315 from 354, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 7:
If we divide 390 by 45, we get 8 and a remainder of 30.
Put 8 as the next digit of the answer. 
Result so far: 18137.8
Deduct 360 from 390 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.

Going ahead to step 8:
300 divided by 45 is 6 with a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 18137.86
If we take 270 away from 300, we end up 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.

Moving on to step 9:
The number 45 fits into 300 6 times, leaving a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 18137.866
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.

In conclusion, the division gives 18137.866 with a balance of 0.003.
