42234 ÷ 23 
Our goal is to divide 42234 by 23.

Moving on to step 1:
23 goes into 4 0 times with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (2) from the dividend, attach it to 4 and continue: 42 / 23

Advancing to step 2:
The number 23 fits into 42 1 times, leaving a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we take 23 away from 42, we end up with 19.
Include the next digit (2) from the dividend after 19, then repeat: 192 / 23

On to step 3:
When dividing 192 by 23, we get 8 with a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 18.0
Subtract 184 from 192 to get 8.
Include the next digit (3) from the dividend after 8, then repeat: 83 / 23

Going ahead to step 4:
83 divided by 23 is 3 with a remainder of 14.
Write down 3 as next digit of the result. 
Result so far: 183.0
Deduct 69 from 83 and we're left with 14.
Take the next digit (4) from the dividend and append it to 14, then repeat: 144 / 23

Step 5:
When dividing 144 by 23, we get 6 with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 1836.0
The remainder is 6 after subtracting 138 from 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 6:
The number 23 fits into 60 2 times, leaving a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 1836.2
Subtracting 46 from 60 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 7:
If we divide 140 by 23, we get 6 and a remainder of 2.
The next digit of our result is 6. 
Result so far: 1836.26
The remainder is 2 after subtracting 138 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
23 goes into 20 0 times with a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1836.26
Subtract 0 from 20 to 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 23 fits into 200 8 times, leaving a remainder of 16.
The number 8 becomes the next digit in our result. 
Result so far: 1836.2608
Subtract 184 from 200 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.

Let's proceed to step 10:
23 goes into 160 6 times with a remainder of 22.
The next digit of our result is 6. 
Result so far: 1836.26086
Deduct 138 from 160 and we're left 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.

Step 11:
23 can be fit into 220 9 times, resulting in a remainder of 13.
Use 9 as the next digit of our solution. 
Result so far: 1836.260869
Subtracting 207 from 220 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 12:
23 goes into 130 5 times with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 1836.2608695
The remainder is 15 after subtracting 115 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 13:
When dividing 150 by 23, we get 6 with a remainder of 12.
The next digit of our result is 6. 
Result so far: 1836.26086956
The remainder is 12 after subtracting 138 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final outcome is 1836.26086956, with a leftover of 1.2e-08.
