642957 divided by 12 
We want to divide 642957 by 12.

Moving on to step 1:
When dividing 6 by 12, we get 0 with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Fetch the next digit (4) from the dividend, attach it to 6 and continue: 64 / 12

Moving on to step 2:
12 goes into 64 5 times with a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 60 from 64 leaves us with 4.
Bring next digit (2) of the dividend behind the 4 and repeat the process: 42 / 12

Advancing to step 3:
12 goes into 42 3 times with a remainder of 6.
The next digit of our result is 3. 
Result so far: 53.0
The remainder is 6 after subtracting 36 from 42.
Bring next digit (9) of the dividend behind the 6 and repeat the process: 69 / 12

Step 4:
12 can be fit into 69 5 times, resulting in a remainder of 9.
The next digit of our result is 5. 
Result so far: 535.0
If we take 60 away from 69, we end up with 9.
Take the next digit (5) from the dividend and append it to 9, then repeat: 95 / 12

On to step 5:
If we divide 95 by 12, we get 7 and a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 5357.0
Subtract 84 from 95 to get 11.
Grab the next digit (7) from the dividend, add it to 11, then carry on: 117 / 12

Step 6:
12 can be fit into 117 9 times, resulting in a remainder of 9.
The next digit of our result is 9. 
Result so far: 53579.0
Subtracting 108 from 117 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Moving on to step 7:
90 divided by 12 is 7 with a remainder of 6.
The number 7 becomes the next digit in our result. 
Result so far: 53579.7
The remainder is 6 after subtracting 84 from 90.
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:
The number 12 fits into 60 5 times, leaving a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 53579.75
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.

Moving on to step 9:
When dividing 0 by 12, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 53579.75
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:
If we divide 0 by 12, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 53579.75
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.

In conclusion, the division gives 53579.75 with a balance of 0.0.
