206461 ÷ 12 
Our goal is to divide 206461 by 12.

Going ahead to step 1:
When dividing 2 by 12, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 12

Advancing to step 2:
If we divide 20 by 12, we get 1 and a remainder of 8.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 12 from 20, we get 8.
Include the next digit (6) from the dividend after 8, then repeat: 86 / 12

On to step 3:
86 divided by 12 is 7 with a remainder of 2.
The number 7 becomes the next digit in our result. 
Result so far: 17.0
If we subtract 84 from 86, we get 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 12

Going ahead to step 4:
The number 12 fits into 24 2 times, leaving a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 172.0
The remainder is 0 after subtracting 24 from 24.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 12

On to step 5:
When dividing 6 by 12, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 1720.0
The remainder is 6 after subtracting 0 from 6.
Take the next digit (1) from the dividend and append it to 6, then repeat: 61 / 12

On to step 6:
When dividing 61 by 12, we get 5 with a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 17205.0
Subtracting 60 from 61 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 7:
12 can be fit into 10 0 times, resulting in a remainder of 10.
The next digit of our result is 0. 
Result so far: 17205.0
Deduct 0 from 10 and we're left with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 8:
The number 12 fits into 100 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 17205.08
If we subtract 96 from 100, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 9:
12 can be fit into 40 3 times, resulting in a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 17205.083
Subtract 36 from 40 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 10:
When dividing 40 by 12, we get 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 17205.0833
Subtracting 36 from 40 leaves us 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.

After the division, we end up with 17205.0833 and a remainder of 4e-05.
