Let's divide 200458 by 12
We want to figure out the number of times 200458 can be divided by 12.

Let's proceed to step 1:
The number 12 fits into 2 0 times, leaving a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Fetch the next digit (0) from the dividend, attach it to 2 and continue: 20 / 12

Moving on to step 2:
The number 12 fits into 20 1 times, leaving a remainder of 8.
Use 1 as the next digit of our solution. 
Result so far: 1.0
If we subtract 12 from 20, we get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 12

Advancing to step 3:
12 can be fit into 80 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 16.0
The remainder is 8 after subtracting 72 from 80.
Take the next digit (4) from the dividend and append it to 8, then repeat: 84 / 12

Advancing to step 4:
84 divided by 12 is 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 167.0
If we take 84 away from 84, we end up with 0.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 12

On to step 5:
5 divided by 12 is 0 with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 1670.0
Subtracting 0 from 5 leaves us with 5.
Fetch the next digit (8) from the dividend, attach it to 5 and continue: 58 / 12

On to step 6:
12 goes into 58 4 times with a remainder of 10.
Use 4 as the next digit of our solution. 
Result so far: 16704.0
Deduct 48 from 58 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.

Moving on to step 7:
If we divide 100 by 12, we get 8 and a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 16704.8
Subtracting 96 from 100 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.

Going ahead to step 8:
12 can be fit into 40 3 times, resulting in a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 16704.83
If we subtract 36 from 40, 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: 16704.833
If we take 36 away from 40, we end up 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.

The final result is 16704.833 with a remainder of 0.0004.
