Let's divide 209358 by 12
Our goal is to divide 209358 by 12.

On to step 1:
12 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Bring next digit (0) of the dividend behind the 2 and repeat the process: 20 / 12

Moving on to step 2:
12 goes into 20 1 times with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 12 from 20, we get 8.
Fetch the next digit (9) from the dividend, attach it to 8 and continue: 89 / 12

Let's proceed to step 3:
12 can be fit into 89 7 times, resulting in a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 17.0
The remainder is 5 after subtracting 84 from 89.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 12

Moving on to step 4:
53 divided by 12 is 4 with a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 174.0
If we take 48 away from 53, we end up with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 12

Let's proceed to step 5:
The number 12 fits into 55 4 times, leaving a remainder of 7.
Record the quotient 4 as the next digit in the result. 
Result so far: 1744.0
The remainder is 7 after subtracting 48 from 55.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 12

Let's proceed to step 6:
The number 12 fits into 78 6 times, leaving a remainder of 6.
The next digit of our result is 6. 
Result so far: 17446.0
Subtract 72 from 78 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 7:
12 goes into 60 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 17446.5
Subtract 60 from 60 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

On to step 8:
0 divided by 12 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 17446.5
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Going ahead to step 9:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 17446.5
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 17446.5 and a remainder of 0.0.
