We divide 542770 by 42
We want to figure out the number of times 542770 can be divided by 42.

Moving on to step 1:
If we divide 5 by 42, we get 0 and 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.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 42

Moving on to step 2:
When dividing 54 by 42, we get 1 with a remainder of 12.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 42 from 54 leaves us with 12.
Bring next digit (2) of the dividend behind the 12 and repeat the process: 122 / 42

Going ahead to step 3:
If we divide 122 by 42, we get 2 and a remainder of 38.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Subtracting 84 from 122 leaves us with 38.
Append the next digit (7) from the dividend to 38 and continue with: 387 / 42

Moving on to step 4:
If we divide 387 by 42, we get 9 and a remainder of 9.
The number 9 becomes the next digit in our result. 
Result so far: 129.0
Subtract 378 from 387 to get 9.
Bring next digit (7) of the dividend behind the 9 and repeat the process: 97 / 42

On to step 5:
If we divide 97 by 42, we get 2 and a remainder of 13.
Put 2 as the next digit of the answer. 
Result so far: 1292.0
Subtracting 84 from 97 leaves us with 13.
Include the next digit (0) from the dividend after 13, then repeat: 130 / 42

Let's proceed to step 6:
42 can be fit into 130 3 times, resulting in a remainder of 4.
The next digit of our result is 3. 
Result so far: 12923.0
Deduct 126 from 130 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 7:
When dividing 40 by 42, we get 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 12923.0
Subtracting 0 from 40 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Step 8:
When dividing 400 by 42, we get 9 with a remainder of 22.
Write down 9 as next digit of the result. 
Result so far: 12923.09
If we subtract 378 from 400, we get 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 9:
When dividing 220 by 42, we get 5 with a remainder of 10.
Use 5 as the next digit of our solution. 
Result so far: 12923.095
Deduct 210 from 220 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Advancing to step 10:
If we divide 100 by 42, we get 2 and a remainder of 16.
Write down 2 as next digit of the result. 
Result so far: 12923.0952
Subtracting 84 from 100 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
160 divided by 42 is 3 with a remainder of 34.
Write down 3 as next digit of the result. 
Result so far: 12923.09523
The remainder is 34 after subtracting 126 from 160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 12:
42 can be fit into 340 8 times, resulting in a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 12923.095238
Subtract 336 from 340 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 13:
40 divided by 42 is 0 with a remainder of 40.
The next digit of our result is 0. 
Result so far: 12923.095238
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 14:
42 can be fit into 400 9 times, resulting in a remainder of 22.
The number 9 becomes the next digit in our result. 
Result so far: 12923.09523809
If we take 378 away from 400, we end up with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

In conclusion, the division gives 12923.09523809 with a balance of 2.2e-08.
