We're dividing 412943 by 12 
We want to divide 412943 by 12.

Step 1:
12 goes into 4 0 times with a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 12

On to step 2:
The number 12 fits into 41 3 times, leaving a remainder of 5.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
Deduct 36 from 41 and we're left with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 12

Step 3:
If we divide 52 by 12, we get 4 and a remainder of 4.
The next digit of our result is 4. 
Result so far: 34.0
If we take 48 away from 52, we end up with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 12

Step 4:
If we divide 49 by 12, we get 4 and a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 344.0
The remainder is 1 after subtracting 48 from 49.
Append the next digit (4) from the dividend to 1 and continue with: 14 / 12

On to step 5:
The number 12 fits into 14 1 times, leaving a remainder of 2.
The next digit of our result is 1. 
Result so far: 3441.0
If we subtract 12 from 14, we get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 12

On to step 6:
23 divided by 12 is 1 with a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 34411.0
The remainder is 11 after subtracting 12 from 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Moving on to step 7:
12 goes into 110 9 times with a remainder of 2.
Use 9 as the next digit of our solution. 
Result so far: 34411.9
If we subtract 108 from 110, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 8:
12 goes into 20 1 times with a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 34411.91
If we take 12 away from 20, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 9:
12 can be fit into 80 6 times, resulting in a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 34411.916
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 10:
12 goes into 80 6 times with a remainder of 8.
The next digit of our result is 6. 
Result so far: 34411.9166
If we take 72 away from 80, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

In conclusion, the division gives 34411.9166 with a balance of 8e-05.
