549132 ÷ 42 
We're looking to find how many times 42 goes into 549132.

Step 1:
42 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 42

Going ahead to step 2:
54 divided by 42 is 1 with a remainder of 12.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 42 from 54, we get 12.
Append the next digit (9) from the dividend to 12 and continue with: 129 / 42

On to step 3:
129 divided by 42 is 3 with a remainder of 3.
Use 3 as the next digit of our solution. 
Result so far: 13.0
Subtract 126 from 129 to get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 42

Advancing to step 4:
The number 42 fits into 31 0 times, leaving a remainder of 31.
The number 0 becomes the next digit in our result. 
Result so far: 130.0
If we take 0 away from 31, we end up with 31.
Grab the next digit (3) from the dividend, add it to 31, then carry on: 313 / 42

On to step 5:
When dividing 313 by 42, we get 7 with a remainder of 19.
The number 7 becomes the next digit in our result. 
Result so far: 1307.0
If we take 294 away from 313, we end up with 19.
Bring next digit (2) of the dividend behind the 19 and repeat the process: 192 / 42

Moving on to step 6:
42 can be fit into 192 4 times, resulting in a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 13074.0
The remainder is 24 after subtracting 168 from 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Going ahead to step 7:
42 can be fit into 240 5 times, resulting in a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 13074.5
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 8:
If we divide 300 by 42, we get 7 and a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 13074.57
If we subtract 294 from 300, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 9:
42 goes into 60 1 times with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 13074.571
Subtract 42 from 60 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 10:
180 divided by 42 is 4 with a remainder of 12.
Write down 4 as next digit of the result. 
Result so far: 13074.5714
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 11:
120 divided by 42 is 2 with a remainder of 36.
Write down 2 as next digit of the result. 
Result so far: 13074.57142
Subtracting 84 from 120 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 12:
360 divided by 42 is 8 with a remainder of 24.
The next digit of our result is 8. 
Result so far: 13074.571428
Deduct 336 from 360 and we're left with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 13:
240 divided by 42 is 5 with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 13074.5714285
If we take 210 away from 240, 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.

Step 14:
42 can be fit into 300 7 times, resulting in a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 13074.57142857
Subtract 294 from 300 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 13074.57142857 with a remaining 6e-09.
