Let's divide 309661 by 12
We want to figure out the number of times 309661 can be divided by 12.

Moving on to step 1:
The number 12 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 12

Let's proceed to step 2:
12 goes into 30 2 times with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Subtract 24 from 30 to get 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 12

Moving on to step 3:
12 goes into 69 5 times with a remainder of 9.
Write down 5 as next digit of the result. 
Result so far: 25.0
The remainder is 9 after subtracting 60 from 69.
Append the next digit (6) from the dividend to 9 and continue with: 96 / 12

Let's proceed to step 4:
12 can be fit into 96 8 times, resulting in a remainder of 0.
Record the quotient 8 as the next digit in the result. 
Result so far: 258.0
If we subtract 96 from 96, we get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 12

Let's proceed to step 5:
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: 2580.0
If we take 0 away from 6, we end up with 6.
Include the next digit (1) from the dividend after 6, then repeat: 61 / 12

Going ahead to step 6:
12 can be fit into 61 5 times, resulting in a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 25805.0
If we subtract 60 from 61, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 7:
12 can be fit into 10 0 times, resulting in a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 25805.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
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: 25805.08
The remainder is 4 after subtracting 96 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 9:
12 goes into 40 3 times with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 25805.083
The remainder is 4 after subtracting 36 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
40 divided by 12 is 3 with a remainder of 4.
Write down 3 as next digit of the result. 
Result so far: 25805.0833
If we take 36 away from 40, we end up 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.

The final result is 25805.0833 with a remainder of 4e-05.
