Let's divide 4234 by 42
We're looking to find how many times 42 goes into 4234.

Step 1:
42 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 42

Moving on to step 2:
When dividing 42 by 42, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 42 from 42 and we're left with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 42

On to step 3:
42 goes into 3 0 times with a remainder of 3.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 3 after subtracting 0 from 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 42

Advancing to step 4:
When dividing 34 by 42, we get 0 with a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
Subtracting 0 from 34 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Advancing to step 5:
If we divide 340 by 42, we get 8 and a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 100.8
If we subtract 336 from 340, we 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 6:
42 goes into 40 0 times with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 100.8
Deduct 0 from 40 and we're left 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 7:
42 goes into 400 9 times with a remainder of 22.
Use 9 as the next digit of our solution. 
Result so far: 100.809
Subtracting 378 from 400 leaves us 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.

Let's proceed to step 8:
The number 42 fits into 220 5 times, leaving a remainder of 10.
Write down 5 as next digit of the result. 
Result so far: 100.8095
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.

Let's proceed to step 9:
42 goes into 100 2 times with a remainder of 16.
Record the quotient 2 as the next digit in the result. 
Result so far: 100.80952
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 10:
When dividing 160 by 42, we get 3 with a remainder of 34.
Use 3 as the next digit of our solution. 
Result so far: 100.809523
Subtract 126 from 160 to get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 11:
When dividing 340 by 42, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 100.8095238
If we subtract 336 from 340, we 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 12:
42 goes into 40 0 times with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.8095238
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

In conclusion, the division gives 100.8095238 with a balance of 4e-08.
