We look at the division of 231124 by 1 
Let's see how many times 1 fits into 231124.

Advancing to step 1:
The number 1 fits into 2 2 times, leaving a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Deduct 2 from 2 and we're left with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 1

Advancing to step 2:
The number 1 fits into 3 3 times, leaving a remainder of 0.
The number 3 becomes the next digit in our result. 
Result so far: 23.0
Subtracting 3 from 3 leaves us with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

Step 3:
When dividing 1 by 1, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 231.0
Subtracting 1 from 1 leaves us with 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 1

Going ahead to step 4:
1 goes into 1 1 times with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 2311.0
Deduct 1 from 1 and we're left with 0.
Append the next digit (2) from the dividend to 0 and continue with: 2 / 1

Going ahead to step 5:
2 divided by 1 is 2 with a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 23112.0
If we take 2 away from 2, we end up with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 1

Advancing to step 6:
When dividing 4 by 1, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 231124.0
Subtract 4 from 4 to 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.

Step 7:
If we divide 0 by 1, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 231124.0
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.
Use 0 as the next digit of our solution. 
Result so far: 231124.0
If we subtract 0 from 0, 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.

The quotient of the division is 231124.0, and the remainder is 0.0.
