We look at the division of 123462 by 43 
Let's see how many times 43 fits into 123462.

Step 1:
When dividing 1 by 43, we get 0 with a remainder of 1.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 43

Let's proceed to step 2:
When dividing 12 by 43, we get 0 with a remainder of 12.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Fetch the next digit (3) from the dividend, attach it to 12 and continue: 123 / 43

Going ahead to step 3:
123 divided by 43 is 2 with a remainder of 37.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 86 from 123, we get 37.
Bring next digit (4) of the dividend behind the 37 and repeat the process: 374 / 43

Let's proceed to step 4:
43 goes into 374 8 times with a remainder of 30.
The next digit of our result is 8. 
Result so far: 28.0
Deduct 344 from 374 and we're left with 30.
Append the next digit (6) from the dividend to 30 and continue with: 306 / 43

Advancing to step 5:
When dividing 306 by 43, we get 7 with a remainder of 5.
The next digit of our result is 7. 
Result so far: 287.0
Subtracting 301 from 306 leaves us with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 43

Moving on to step 6:
The number 43 fits into 52 1 times, leaving a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 2871.0
If we subtract 43 from 52, we get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 7:
90 divided by 43 is 2 with a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 2871.2
Deduct 86 from 90 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 8:
When dividing 40 by 43, we get 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 2871.2
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
If we divide 400 by 43, we get 9 and a remainder of 13.
The number 9 becomes the next digit in our result. 
Result so far: 2871.209
The remainder is 13 after subtracting 387 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Step 10:
130 divided by 43 is 3 with a remainder of 1.
Use 3 as the next digit of our solution. 
Result so far: 2871.2093
The remainder is 1 after subtracting 129 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 11:
10 divided by 43 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 2871.2093
Subtract 0 from 10 to get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 12:
If we divide 100 by 43, we get 2 and a remainder of 14.
Put 2 as the next digit of the answer. 
Result so far: 2871.209302
Subtract 86 from 100 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Step 13:
When dividing 140 by 43, we get 3 with a remainder of 11.
Use 3 as the next digit of our solution. 
Result so far: 2871.2093023
The remainder is 11 after subtracting 129 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 14:
43 goes into 110 2 times with a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 2871.20930232
If we subtract 86 from 110, we 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.

The final result is 2871.20930232 with a remainder of 2.4e-08.
