257414 divided by 12 
Our goal is to divide 257414 by 12.

On to step 1:
If we divide 2 by 12, we get 0 and a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 12

Step 2:
25 divided by 12 is 2 with a remainder of 1.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 24 away from 25, we end up with 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 12

Let's proceed to step 3:
12 can be fit into 17 1 times, resulting in a remainder of 5.
The next digit of our result is 1. 
Result so far: 21.0
If we take 12 away from 17, we end up with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 12

On to step 4:
If we divide 54 by 12, we get 4 and a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 214.0
Deduct 48 from 54 and we're left with 6.
Fetch the next digit (1) from the dividend, attach it to 6 and continue: 61 / 12

Moving on to step 5:
12 goes into 61 5 times with a remainder of 1.
The next digit of our result is 5. 
Result so far: 2145.0
Subtracting 60 from 61 leaves us with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 12

Going ahead to step 6:
14 divided by 12 is 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 21451.0
If we take 12 away from 14, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 7:
12 goes into 20 1 times with a remainder of 8.
The next digit of our result is 1. 
Result so far: 21451.1
If we subtract 12 from 20, we 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.

Let's proceed to step 8:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 21451.16
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.

Let's proceed to step 9:
80 divided by 12 is 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 21451.166
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.

The final result is 21451.166 with a remainder of 0.0008.
