230643 ÷ 12 
Let's see how many times 12 fits into 230643.

On to step 1:
The number 12 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 12

Going ahead to step 2:
When dividing 23 by 12, we get 1 with a remainder of 11.
The next digit of our result is 1. 
Result so far: 1.0
The remainder is 11 after subtracting 12 from 23.
Include the next digit (0) from the dividend after 11, then repeat: 110 / 12

Moving on to step 3:
When dividing 110 by 12, we get 9 with a remainder of 2.
Put 9 as the next digit of the answer. 
Result so far: 19.0
Deduct 108 from 110 and we're left with 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 12

Advancing to step 4:
12 can be fit into 26 2 times, resulting in a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 192.0
The remainder is 2 after subtracting 24 from 26.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 12

Step 5:
24 divided by 12 is 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 1922.0
Subtracting 24 from 24 leaves us with 0.
Grab the next digit (3) from the dividend, add it to 0, then carry on: 3 / 12

On to step 6:
12 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 19220.0
The remainder is 3 after subtracting 0 from 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 7:
30 divided by 12 is 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 19220.2
Subtracting 24 from 30 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
When dividing 60 by 12, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 19220.25
Deduct 60 from 60 and we're left 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.

Advancing to step 9:
0 divided by 12 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 19220.25
If we subtract 0 from 0, we 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.

Let's proceed to step 10:
12 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 19220.25
Deduct 0 from 0 and we're left 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.

The quotient of the division is 19220.25, and the remainder is 0.0.
