549069 ÷ 42 
We want to divide 549069 by 42.

Step 1:
The number 42 fits into 5 0 times, leaving a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 42

Advancing to step 2:
If we divide 54 by 42, we get 1 and a remainder of 12.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 12 after subtracting 42 from 54.
Include the next digit (9) from the dividend after 12, then repeat: 129 / 42

Going ahead to step 3:
42 can be fit into 129 3 times, resulting in a remainder of 3.
Record the quotient 3 as the next digit in the result. 
Result so far: 13.0
Subtracting 126 from 129 leaves us with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 42

Let's proceed to step 4:
42 goes into 30 0 times with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 130.0
If we take 0 away from 30, we end up with 30.
Fetch the next digit (6) from the dividend, attach it to 30 and continue: 306 / 42

Advancing to step 5:
When dividing 306 by 42, we get 7 with a remainder of 12.
Use 7 as the next digit of our solution. 
Result so far: 1307.0
Subtract 294 from 306 to get 12.
Fetch the next digit (9) from the dividend, attach it to 12 and continue: 129 / 42

Moving on to step 6:
When dividing 129 by 42, we get 3 with a remainder of 3.
The next digit of our result is 3. 
Result so far: 13073.0
Subtracting 126 from 129 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
If we divide 30 by 42, we get 0 and a remainder of 30.
Use 0 as the next digit of our solution. 
Result so far: 13073.0
The remainder is 30 after subtracting 0 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 8:
300 divided by 42 is 7 with a remainder of 6.
The next digit of our result is 7. 
Result so far: 13073.07
If we take 294 away from 300, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 9:
If we divide 60 by 42, we get 1 and a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 13073.071
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 10:
42 can be fit into 180 4 times, resulting in a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 13073.0714
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 11:
The number 42 fits into 120 2 times, leaving a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 13073.07142
If we subtract 84 from 120, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 12:
42 goes into 360 8 times with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 13073.071428
The remainder is 24 after subtracting 336 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 13:
42 can be fit into 240 5 times, resulting in a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 13073.0714285
Deduct 210 from 240 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 14:
300 divided by 42 is 7 with a remainder of 6.
The next digit of our result is 7. 
Result so far: 13073.07142857
Deduct 294 from 300 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The final result is 13073.07142857 with a remainder of 6e-09.
