We look at the division of 549066 by 45 
We want to divide 549066 by 45.

Going ahead to step 1:
5 divided by 45 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 45

On to step 2:
54 divided by 45 is 1 with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 9 after subtracting 45 from 54.
Append the next digit (9) from the dividend to 9 and continue with: 99 / 45

Moving on to step 3:
99 divided by 45 is 2 with a remainder of 9.
The next digit of our result is 2. 
Result so far: 12.0
If we subtract 90 from 99, we get 9.
Fetch the next digit (0) from the dividend, attach it to 9 and continue: 90 / 45

Advancing to step 4:
45 can be fit into 90 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 122.0
If we subtract 90 from 90, we get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 45

Going ahead to step 5:
45 goes into 6 0 times with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 1220.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (6) from the dividend and append it to 6, then repeat: 66 / 45

Advancing to step 6:
66 divided by 45 is 1 with a remainder of 21.
Put 1 as the next digit of the answer. 
Result so far: 12201.0
Deduct 45 from 66 and we're left with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 7:
45 goes into 210 4 times with a remainder of 30.
Record the quotient 4 as the next digit in the result. 
Result so far: 12201.4
If we subtract 180 from 210, 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:
The number 45 fits into 300 6 times, leaving a remainder of 30.
Record the quotient 6 as the next digit in the result. 
Result so far: 12201.46
The remainder is 30 after subtracting 270 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 9:
45 can be fit into 300 6 times, resulting in a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 12201.466
Subtracting 270 from 300 leaves us 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.

The quotient of the division is 12201.466, and the remainder is 0.003.
