489703 ÷ 12 
We want to figure out the number of times 489703 can be divided by 12.

Let's proceed to step 1:
4 divided by 12 is 0 with a remainder of 4.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 12

On to step 2:
48 divided by 12 is 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
Subtract 48 from 48 to get 0.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 12

Step 3:
9 divided by 12 is 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 40.0
Deduct 0 from 9 and we're left with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 12

Moving on to step 4:
97 divided by 12 is 8 with a remainder of 1.
Write down 8 as next digit of the result. 
Result so far: 408.0
If we take 96 away from 97, we end up with 1.
Include the next digit (0) from the dividend after 1, then repeat: 10 / 12

Moving on to step 5:
12 goes into 10 0 times with a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 4080.0
Deduct 0 from 10 and we're left with 10.
Include the next digit (3) from the dividend after 10, then repeat: 103 / 12

Going ahead to step 6:
When dividing 103 by 12, we get 8 with a remainder of 7.
Put 8 as the next digit of the answer. 
Result so far: 40808.0
If we take 96 away from 103, we end up with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 7:
If we divide 70 by 12, we get 5 and a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 40808.5
If we take 60 away from 70, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 8:
If we divide 100 by 12, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 40808.58
Subtracting 96 from 100 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.

Moving on to step 9:
12 goes into 40 3 times with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 40808.583
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.

Going ahead to step 10:
40 divided by 12 is 3 with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 40808.5833
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.

After the division, we end up with 40808.5833 and a remainder of 4e-05.
