Let's divide 134858 by 42
We want to divide 134858 by 42.

Advancing to step 1:
1 divided by 42 is 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 42

Step 2:
42 can be fit into 13 0 times, resulting in a remainder of 13.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 13 leaves us with 13.
Bring next digit (4) of the dividend behind the 13 and repeat the process: 134 / 42

On to step 3:
If we divide 134 by 42, we get 3 and a remainder of 8.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 126 from 134 leaves us with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 42

On to step 4:
42 can be fit into 88 2 times, resulting in a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 32.0
Subtract 84 from 88 to get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 42

Step 5:
42 goes into 45 1 times with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 321.0
The remainder is 3 after subtracting 42 from 45.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 42

Let's proceed to step 6:
38 divided by 42 is 0 with a remainder of 38.
Use 0 as the next digit of our solution. 
Result so far: 3210.0
Subtract 0 from 38 to get 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 7:
42 goes into 380 9 times with a remainder of 2.
Record the quotient 9 as the next digit in the result. 
Result so far: 3210.9
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.

Going ahead to step 8:
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: 3210.9
If we subtract 0 from 20, we get 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 9:
The number 42 fits into 200 4 times, leaving a remainder of 32.
The next digit of our result is 4. 
Result so far: 3210.904
If we take 168 away from 200, we end up 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.

Going ahead to step 10:
The number 42 fits into 320 7 times, leaving a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 3210.9047
If we take 294 away from 320, we end up 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.

Moving on to step 11:
When dividing 260 by 42, we get 6 with a remainder of 8.
Record the quotient 6 as the next digit in the result. 
Result so far: 3210.90476
The remainder is 8 after subtracting 252 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 12:
When dividing 80 by 42, we get 1 with a remainder of 38.
Write down 1 as next digit of the result. 
Result so far: 3210.904761
The remainder is 38 after subtracting 42 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 13:
If we divide 380 by 42, we get 9 and a remainder of 2.
The next digit of our result is 9. 
Result so far: 3210.9047619
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 14:
42 goes into 20 0 times with a remainder of 20.
Put 0 as the next digit of the answer. 
Result so far: 3210.9047619
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.

Our division results in 3210.9047619 with a remaining 2e-08.
