We look at the division of 158930 by 42 
Let's see how many times 42 fits into 158930.

Moving on to step 1:
When dividing 1 by 42, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 42

Step 2:
The number 42 fits into 15 0 times, leaving a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 15, we get 15.
Bring next digit (8) of the dividend behind the 15 and repeat the process: 158 / 42

Moving on to step 3:
If we divide 158 by 42, we get 3 and a remainder of 32.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 126 from 158 and we're left with 32.
Append the next digit (9) from the dividend to 32 and continue with: 329 / 42

Let's proceed to step 4:
42 can be fit into 329 7 times, resulting in a remainder of 35.
Write down 7 as next digit of the result. 
Result so far: 37.0
Subtract 294 from 329 to get 35.
Fetch the next digit (3) from the dividend, attach it to 35 and continue: 353 / 42

Step 5:
42 can be fit into 353 8 times, resulting in a remainder of 17.
The number 8 becomes the next digit in our result. 
Result so far: 378.0
Deduct 336 from 353 and we're left with 17.
Append the next digit (0) from the dividend to 17 and continue with: 170 / 42

Moving on to step 6:
The number 42 fits into 170 4 times, leaving a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 3784.0
Deduct 168 from 170 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
42 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 3784.0
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 8:
42 can be fit into 200 4 times, resulting in a remainder of 32.
Put 4 as the next digit of the answer. 
Result so far: 3784.04
Deduct 168 from 200 and we're left with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
42 goes into 320 7 times with a remainder of 26.
Put 7 as the next digit of the answer. 
Result so far: 3784.047
Subtracting 294 from 320 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Let's proceed to step 10:
42 goes into 260 6 times with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 3784.0476
Deduct 252 from 260 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 11:
80 divided by 42 is 1 with a remainder of 38.
Use 1 as the next digit of our solution. 
Result so far: 3784.04761
If we take 42 away from 80, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 12:
When dividing 380 by 42, we get 9 with a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 3784.047619
The remainder is 2 after subtracting 378 from 380.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 13:
42 can be fit into 20 0 times, resulting in a remainder of 20.
The next digit of our result is 0. 
Result so far: 3784.047619
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 14:
If we divide 200 by 42, we get 4 and a remainder of 32.
The next digit of our result is 4. 
Result so far: 3784.04761904
Subtracting 168 from 200 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

In conclusion, the division gives 3784.04761904 with a balance of 3.2e-08.
