549045 divided by 42 
Our goal is to divide 549045 by 42.

Going ahead to step 1:
42 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 42

Advancing to step 2:
If we divide 54 by 42, we get 1 and a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 42 from 54 and we're left with 12.
Grab the next digit (9) from the dividend, add it to 12, then carry on: 129 / 42

Moving on to step 3:
129 divided by 42 is 3 with a remainder of 3.
Put 3 as the next digit of the answer. 
Result so far: 13.0
Subtract 126 from 129 to get 3.
Append the next digit (0) from the dividend to 3 and continue with: 30 / 42

Step 4:
42 can be fit into 30 0 times, resulting in a remainder of 30.
The next digit of our result is 0. 
Result so far: 130.0
If we take 0 away from 30, we end up with 30.
Append the next digit (4) from the dividend to 30 and continue with: 304 / 42

Let's proceed to step 5:
If we divide 304 by 42, we get 7 and a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 1307.0
If we take 294 away from 304, we end up with 10.
Take the next digit (5) from the dividend and append it to 10, then repeat: 105 / 42

Let's proceed to step 6:
When dividing 105 by 42, we get 2 with a remainder of 21.
The number 2 becomes the next digit in our result. 
Result so far: 13072.0
Subtract 84 from 105 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 7:
The number 42 fits into 210 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 13072.5
If we take 210 away from 210, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
The number 42 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 13072.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
42 goes into 0 0 times with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 13072.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 13072.5, and the remainder is 0.0.
