Let's divide 355158 by 42
We're looking to find how many times 42 goes into 355158.

Step 1:
42 goes into 3 0 times with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (5) of the dividend behind the 3 and repeat the process: 35 / 42

Step 2:
The number 42 fits into 35 0 times, leaving a remainder of 35.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 35 and we're left with 35.
Fetch the next digit (5) from the dividend, attach it to 35 and continue: 355 / 42

Step 3:
42 goes into 355 8 times with a remainder of 19.
The next digit of our result is 8. 
Result so far: 8.0
If we subtract 336 from 355, we get 19.
Append the next digit (1) from the dividend to 19 and continue with: 191 / 42

Going ahead to step 4:
42 goes into 191 4 times with a remainder of 23.
Use 4 as the next digit of our solution. 
Result so far: 84.0
Subtracting 168 from 191 leaves us with 23.
Take the next digit (5) from the dividend and append it to 23, then repeat: 235 / 42

Advancing to step 5:
235 divided by 42 is 5 with a remainder of 25.
Put 5 as the next digit of the answer. 
Result so far: 845.0
Subtracting 210 from 235 leaves us with 25.
Include the next digit (8) from the dividend after 25, then repeat: 258 / 42

Moving on to step 6:
When dividing 258 by 42, we get 6 with a remainder of 6.
Use 6 as the next digit of our solution. 
Result so far: 8456.0
Subtracting 252 from 258 leaves us 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.

Going ahead to step 7:
The number 42 fits into 60 1 times, leaving a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 8456.1
If we subtract 42 from 60, we 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.

Let's proceed to step 8:
The number 42 fits into 180 4 times, leaving a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 8456.14
If we take 168 away from 180, we end up 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.

Going ahead to step 9:
120 divided by 42 is 2 with a remainder of 36.
The next digit of our result is 2. 
Result so far: 8456.142
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.

Let's proceed to step 10:
360 divided by 42 is 8 with a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 8456.1428
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.

Let's proceed to step 11:
240 divided by 42 is 5 with a remainder of 30.
The next digit of our result is 5. 
Result so far: 8456.14285
Subtracting 210 from 240 leaves us 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.

Moving on to step 12:
The number 42 fits into 300 7 times, leaving a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 8456.142857
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 13:
When dividing 60 by 42, we get 1 with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 8456.1428571
Subtracting 42 from 60 leaves us 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.

Moving on to step 14:
When dividing 180 by 42, we get 4 with a remainder of 12.
Use 4 as the next digit of our solution. 
Result so far: 8456.14285714
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.

Our division results in 8456.14285714 with a remaining 1.2e-08.
