We divide 804270 by 45
Our goal is to divide 804270 by 45.

On to step 1:
8 divided by 45 is 0 with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 45

Step 2:
If we divide 80 by 45, we get 1 and a remainder of 35.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we take 45 away from 80, we end up with 35.
Bring next digit (4) of the dividend behind the 35 and repeat the process: 354 / 45

Going ahead to step 3:
When dividing 354 by 45, we get 7 with a remainder of 39.
The next digit of our result is 7. 
Result so far: 17.0
If we subtract 315 from 354, we get 39.
Bring next digit (2) of the dividend behind the 39 and repeat the process: 392 / 45

Step 4:
The number 45 fits into 392 8 times, leaving a remainder of 32.
The next digit of our result is 8. 
Result so far: 178.0
The remainder is 32 after subtracting 360 from 392.
Include the next digit (7) from the dividend after 32, then repeat: 327 / 45

Moving on to step 5:
The number 45 fits into 327 7 times, leaving a remainder of 12.
Record the quotient 7 as the next digit in the result. 
Result so far: 1787.0
The remainder is 12 after subtracting 315 from 327.
Take the next digit (0) from the dividend and append it to 12, then repeat: 120 / 45

Moving on to step 6:
45 can be fit into 120 2 times, resulting in a remainder of 30.
Record the quotient 2 as the next digit in the result. 
Result so far: 17872.0
If we subtract 90 from 120, we 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.

Step 7:
300 divided by 45 is 6 with a remainder of 30.
The next digit of our result is 6. 
Result so far: 17872.6
If we subtract 270 from 300, we 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.

Going ahead to step 8:
45 goes into 300 6 times with a remainder of 30.
Put 6 as the next digit of the answer. 
Result so far: 17872.66
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.

Our division results in 17872.66 with a remaining 0.03.
