We look at the division of 233451 by 42 
We're looking to find how many times 42 goes into 233451.

On to step 1:
2 divided by 42 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (3) from the dividend after 2, then repeat: 23 / 42

Let's proceed to step 2:
When dividing 23 by 42, we get 0 with a remainder of 23.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Fetch the next digit (3) from the dividend, attach it to 23 and continue: 233 / 42

Step 3:
If we divide 233 by 42, we get 5 and a remainder of 23.
Put 5 as the next digit of the answer. 
Result so far: 5.0
If we take 210 away from 233, we end up with 23.
Append the next digit (4) from the dividend to 23 and continue with: 234 / 42

Going ahead to step 4:
42 goes into 234 5 times with a remainder of 24.
Use 5 as the next digit of our solution. 
Result so far: 55.0
Deduct 210 from 234 and we're left with 24.
Take the next digit (5) from the dividend and append it to 24, then repeat: 245 / 42

Step 5:
The number 42 fits into 245 5 times, leaving a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 555.0
If we take 210 away from 245, we end up with 35.
Bring next digit (1) of the dividend behind the 35 and repeat the process: 351 / 42

Moving on to step 6:
42 can be fit into 351 8 times, resulting in a remainder of 15.
Use 8 as the next digit of our solution. 
Result so far: 5558.0
If we take 336 away from 351, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Moving on to step 7:
If we divide 150 by 42, we get 3 and a remainder of 24.
The next digit of our result is 3. 
Result so far: 5558.3
If we take 126 away from 150, we end up 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.

Going ahead to step 8:
42 goes into 240 5 times with a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 5558.35
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.

On to step 9:
42 goes into 300 7 times with a remainder of 6.
Put 7 as the next digit of the answer. 
Result so far: 5558.357
Subtracting 294 from 300 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.

Let's proceed to step 10:
When dividing 60 by 42, we get 1 with a remainder of 18.
The number 1 becomes the next digit in our result. 
Result so far: 5558.3571
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.

Advancing to step 11:
When dividing 180 by 42, we get 4 with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 5558.35714
Subtracting 168 from 180 leaves us 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 12:
42 goes into 120 2 times with a remainder of 36.
The next digit of our result is 2. 
Result so far: 5558.357142
Subtracting 84 from 120 leaves us with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Advancing to step 13:
360 divided by 42 is 8 with a remainder of 24.
Put 8 as the next digit of the answer. 
Result so far: 5558.3571428
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 14:
42 can be fit into 240 5 times, resulting in a remainder of 30.
Write down 5 as next digit of the result. 
Result so far: 5558.35714285
The remainder is 30 after subtracting 210 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

The final result is 5558.35714285 with a remainder of 3e-08.
