We look at the division of 231450 by 42 
Our goal is to divide 231450 by 42.

Going ahead to step 1:
When dividing 2 by 42, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 42

Going ahead to step 2:
If we divide 23 by 42, we get 0 and a remainder of 23.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 23 leaves us with 23.
Bring next digit (1) of the dividend behind the 23 and repeat the process: 231 / 42

Step 3:
42 can be fit into 231 5 times, resulting in a remainder of 21.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtract 210 from 231 to get 21.
Take the next digit (4) from the dividend and append it to 21, then repeat: 214 / 42

Going ahead to step 4:
The number 42 fits into 214 5 times, leaving a remainder of 4.
Record the quotient 5 as the next digit in the result. 
Result so far: 55.0
The remainder is 4 after subtracting 210 from 214.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 42

Advancing to step 5:
42 can be fit into 45 1 times, resulting in a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 551.0
If we subtract 42 from 45, we get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 42

Moving on to step 6:
The number 42 fits into 30 0 times, leaving a remainder of 30.
The next digit of our result is 0. 
Result so far: 5510.0
Deduct 0 from 30 and we're left 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.

Advancing to step 7:
42 goes into 300 7 times with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 5510.7
Subtract 294 from 300 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 8:
42 can be fit into 60 1 times, resulting in a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 5510.71
Deduct 42 from 60 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 9:
The number 42 fits into 180 4 times, leaving a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 5510.714
The remainder is 12 after subtracting 168 from 180.
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 10:
When dividing 120 by 42, we get 2 with a remainder of 36.
Record the quotient 2 as the next digit in the result. 
Result so far: 5510.7142
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.

On to step 11:
The number 42 fits into 360 8 times, leaving a remainder of 24.
Write down 8 as next digit of the result. 
Result so far: 5510.71428
Subtract 336 from 360 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
When dividing 240 by 42, we get 5 with a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 5510.714285
If we take 210 away from 240, we end up 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 13:
300 divided by 42 is 7 with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 5510.7142857
Subtract 294 from 300 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 14:
When dividing 60 by 42, we get 1 with a remainder of 18.
Write down 1 as next digit of the result. 
Result so far: 5510.71428571
Subtract 42 from 60 to 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.

The final result is 5510.71428571 with a remainder of 1.8e-08.
