Let's divide 492243 by 42
We're looking to find how many times 42 goes into 492243.

Step 1:
The number 42 fits into 4 0 times, leaving a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 42

On to step 2:
42 can be fit into 49 1 times, resulting in a remainder of 7.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 42 from 49 leaves us with 7.
Take the next digit (2) from the dividend and append it to 7, then repeat: 72 / 42

On to step 3:
If we divide 72 by 42, we get 1 and a remainder of 30.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 42 from 72 and we're left with 30.
Grab the next digit (2) from the dividend, add it to 30, then carry on: 302 / 42

On to step 4:
If we divide 302 by 42, we get 7 and a remainder of 8.
Put 7 as the next digit of the answer. 
Result so far: 117.0
If we take 294 away from 302, we end up with 8.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 42

Let's proceed to step 5:
The number 42 fits into 84 2 times, leaving a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 1172.0
The remainder is 0 after subtracting 84 from 84.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 42

Let's proceed to step 6:
42 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 11720.0
Subtract 0 from 3 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 7:
The number 42 fits into 30 0 times, leaving a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 11720.0
If we subtract 0 from 30, 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:
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: 11720.07
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.

Step 9:
The number 42 fits into 60 1 times, leaving a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 11720.071
If we take 42 away from 60, we end up with 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:
When dividing 180 by 42, we get 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 11720.0714
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 11:
The number 42 fits into 120 2 times, leaving a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 11720.07142
Deduct 84 from 120 and we're left 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.

On 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: 11720.071428
Subtract 336 from 360 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

On to step 13:
If we divide 240 by 42, we get 5 and a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 11720.0714285
Subtract 210 from 240 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.

Moving on to step 14:
300 divided by 42 is 7 with a remainder of 6.
Use 7 as the next digit of our solution. 
Result so far: 11720.07142857
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.

Our division results in 11720.07142857 with a remaining 6e-09.
