Let's divide 669249 by 12
Our goal is to divide 669249 by 12.

Going ahead to step 1:
The number 12 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 12

Going ahead to step 2:
12 goes into 66 5 times with a remainder of 6.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
Subtracting 60 from 66 leaves us with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 12

Step 3:
The number 12 fits into 69 5 times, leaving a remainder of 9.
Record the quotient 5 as the next digit in the result. 
Result so far: 55.0
The remainder is 9 after subtracting 60 from 69.
Append the next digit (2) from the dividend to 9 and continue with: 92 / 12

Let's proceed to step 4:
92 divided by 12 is 7 with a remainder of 8.
Use 7 as the next digit of our solution. 
Result so far: 557.0
If we subtract 84 from 92, we get 8.
Grab the next digit (4) from the dividend, add it to 8, then carry on: 84 / 12

Advancing to step 5:
12 can be fit into 84 7 times, resulting in a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 5577.0
The remainder is 0 after subtracting 84 from 84.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 12

Advancing to step 6:
9 divided by 12 is 0 with a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 55770.0
The remainder is 9 after subtracting 0 from 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 7:
If we divide 90 by 12, we get 7 and a remainder of 6.
The next digit of our result is 7. 
Result so far: 55770.7
If we subtract 84 from 90, we 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.

On to step 8:
The number 12 fits into 60 5 times, leaving a remainder of 0.
The number 5 becomes the next digit in our result. 
Result so far: 55770.75
Subtracting 60 from 60 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.

Step 9:
The number 12 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 55770.75
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.

Moving on to step 10:
When dividing 0 by 12, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 55770.75
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.

In conclusion, the division gives 55770.75 with a balance of 0.0.
