Let's divide 489289 by 12
We want to divide 489289 by 12.

Going ahead to step 1:
4 divided by 12 is 0 with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 12

Advancing to step 2:
12 can be fit into 48 4 times, resulting in a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
The remainder is 0 after subtracting 48 from 48.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 12

On to step 3:
If we divide 9 by 12, we get 0 and a remainder of 9.
The next digit of our result is 0. 
Result so far: 40.0
Subtracting 0 from 9 leaves us with 9.
Grab the next digit (2) from the dividend, add it to 9, then carry on: 92 / 12

On to step 4:
12 goes into 92 7 times with a remainder of 8.
Record the quotient 7 as the next digit in the result. 
Result so far: 407.0
Deduct 84 from 92 and we're left with 8.
Bring next digit (8) of the dividend behind the 8 and repeat the process: 88 / 12

Going ahead to step 5:
12 goes into 88 7 times with a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 4077.0
If we subtract 84 from 88, we get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 12

On to step 6:
49 divided by 12 is 4 with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 40774.0
The remainder is 1 after subtracting 48 from 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
When dividing 10 by 12, we get 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 40774.0
If we take 0 away from 10, 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.

Advancing to step 8:
When dividing 100 by 12, we get 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 40774.08
Subtract 96 from 100 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 9:
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: 40774.083
If we subtract 36 from 40, we get 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 10:
When dividing 40 by 12, we get 3 with a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 40774.0833
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 40774.0833 and a remainder of 4e-05.
