We're dividing 674380 by 12 
We want to divide 674380 by 12.

Moving on to step 1:
6 divided by 12 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 12

On to step 2:
When dividing 67 by 12, we get 5 with a remainder of 7.
Write down 5 as next digit of the result. 
Result so far: 5.0
Subtracting 60 from 67 leaves us with 7.
Grab the next digit (4) from the dividend, add it to 7, then carry on: 74 / 12

Going ahead to step 3:
12 can be fit into 74 6 times, resulting in a remainder of 2.
The number 6 becomes the next digit in our result. 
Result so far: 56.0
Deduct 72 from 74 and we're left with 2.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 12

Step 4:
12 can be fit into 23 1 times, resulting in a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 561.0
Deduct 12 from 23 and we're left with 11.
Grab the next digit (8) from the dividend, add it to 11, then carry on: 118 / 12

Going ahead to step 5:
12 goes into 118 9 times with a remainder of 10.
Record the quotient 9 as the next digit in the result. 
Result so far: 5619.0
If we subtract 108 from 118, we get 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 12

Step 6:
If we divide 100 by 12, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 56198.0
Deduct 96 from 100 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 7:
The number 12 fits into 40 3 times, leaving a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 56198.3
Subtracting 36 from 40 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
12 can be fit into 40 3 times, resulting in a remainder of 4.
The next digit of our result is 3. 
Result so far: 56198.33
Deduct 36 from 40 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

In conclusion, the division gives 56198.33 with a balance of 0.004.
