We're dividing 243141 by 1 
Let's see how many times 1 fits into 243141.

Let's proceed to step 1:
When dividing 2 by 1, we get 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
The remainder is 0 after subtracting 2 from 2.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 1

Moving on to step 2:
The number 1 fits into 4 4 times, leaving a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 24.0
If we take 4 away from 4, we end up with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 1

Moving on to step 3:
The number 1 fits into 3 3 times, leaving a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 243.0
If we subtract 3 from 3, we get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

Let's proceed to step 4:
If we divide 1 by 1, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 2431.0
If we take 1 away from 1, we end up with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 1

Moving on to step 5:
When dividing 4 by 1, we get 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 24314.0
The remainder is 0 after subtracting 4 from 4.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 1

Advancing to step 6:
1 divided by 1 is 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 243141.0
If we subtract 1 from 1, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 243141.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
1 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 243141.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 243141.0 and a remainder of 0.0.
