690042 divided by 12 
Our goal is to divide 690042 by 12.

Step 1:
12 can be fit into 6 0 times, resulting in a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 12

Step 2:
12 can be fit into 69 5 times, resulting in a remainder of 9.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtract 60 from 69 to get 9.
Grab the next digit (0) from the dividend, add it to 9, then carry on: 90 / 12

Going ahead to step 3:
12 goes into 90 7 times with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 57.0
If we take 84 away from 90, we end up with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 12

Going ahead to step 4:
12 can be fit into 60 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 575.0
Deduct 60 from 60 and we're left with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 12

On to step 5:
12 can be fit into 4 0 times, resulting in a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 5750.0
Subtracting 0 from 4 leaves us with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 12

Step 6:
12 goes into 42 3 times with a remainder of 6.
The next digit of our result is 3. 
Result so far: 57503.0
If we subtract 36 from 42, 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.

Let's proceed to step 7:
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: 57503.5
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.

Step 8:
When dividing 0 by 12, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 57503.5
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.

On to step 9:
12 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 57503.5
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.

In conclusion, the division gives 57503.5 with a balance of 0.0.
