264398 ÷ 12 
We're looking to find how many times 12 goes into 264398.

Let's proceed to step 1:
When dividing 2 by 12, we get 0 with 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.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 12

Let's proceed to step 2:
When dividing 26 by 12, we get 2 with a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
Subtract 24 from 26 to get 2.
Append the next digit (4) from the dividend to 2 and continue with: 24 / 12

Moving on to step 3:
24 divided by 12 is 2 with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we take 24 away from 24, we end up with 0.
Take the next digit (3) from the dividend and append it to 0, then repeat: 3 / 12

On to step 4:
If we divide 3 by 12, we get 0 and a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 220.0
If we take 0 away from 3, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 12

Advancing to step 5:
The number 12 fits into 39 3 times, leaving a remainder of 3.
The number 3 becomes the next digit in our result. 
Result so far: 2203.0
Deduct 36 from 39 and we're left with 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 12

Going ahead to step 6:
12 goes into 38 3 times with a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 22033.0
If we take 36 away from 38, 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.

On to step 7:
20 divided by 12 is 1 with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 22033.1
Deduct 12 from 20 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.

Step 8:
The number 12 fits into 80 6 times, leaving a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 22033.16
The remainder is 8 after subtracting 72 from 80.
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:
12 goes into 80 6 times with a remainder of 8.
Use 6 as the next digit of our solution. 
Result so far: 22033.166
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 22033.166, and the remainder is 0.0008.
