4115 ÷ 12 
Let's see how many times 12 fits into 4115.

On to step 1:
12 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (1) from the dividend and append it to 4, then repeat: 41 / 12

Going ahead to step 2:
If we divide 41 by 12, we get 3 and a remainder of 5.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 36 from 41 leaves us with 5.
Fetch the next digit (1) from the dividend, attach it to 5 and continue: 51 / 12

On to step 3:
When dividing 51 by 12, we get 4 with a remainder of 3.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Subtracting 48 from 51 leaves us with 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 12

Let's proceed to step 4:
35 divided by 12 is 2 with a remainder of 11.
Record the quotient 2 as the next digit in the result. 
Result so far: 342.0
If we subtract 24 from 35, we get 11.
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 5:
The number 12 fits into 110 9 times, leaving a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 342.9
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 6:
The number 12 fits into 20 1 times, leaving a remainder of 8.
The next digit of our result is 1. 
Result so far: 342.91
Subtracting 12 from 20 leaves us 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.

Moving on to step 7:
When dividing 80 by 12, we get 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 342.916
Deduct 72 from 80 and we're left 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.

Moving on to step 8:
80 divided by 12 is 6 with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 342.9166
Subtract 72 from 80 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 342.9166 and a remainder of 8e-05.
