Let's divide 289378 by 12
Our goal is to divide 289378 by 12.

On to step 1:
2 divided by 12 is 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 12

Going ahead to step 2:
If we divide 28 by 12, we get 2 and a remainder of 4.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 24 away from 28, we end up with 4.
Bring next digit (9) of the dividend behind the 4 and repeat the process: 49 / 12

Advancing to step 3:
12 goes into 49 4 times with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 24.0
Subtracting 48 from 49 leaves us with 1.
Grab the next digit (3) from the dividend, add it to 1, then carry on: 13 / 12

Step 4:
When dividing 13 by 12, we get 1 with a remainder of 1.
Use 1 as the next digit of our solution. 
Result so far: 241.0
If we take 12 away from 13, we end up with 1.
Grab the next digit (7) from the dividend, add it to 1, then carry on: 17 / 12

Moving on to step 5:
If we divide 17 by 12, we get 1 and a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 2411.0
Subtracting 12 from 17 leaves us with 5.
Grab the next digit (8) from the dividend, add it to 5, then carry on: 58 / 12

Advancing to step 6:
When dividing 58 by 12, we get 4 with a remainder of 10.
Put 4 as the next digit of the answer. 
Result so far: 24114.0
Subtract 48 from 58 to 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.

Let's proceed to step 7:
When dividing 100 by 12, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 24114.8
If we take 96 away from 100, 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.

On to step 8:
When dividing 40 by 12, we get 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 24114.83
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.

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: 24114.833
Subtract 36 from 40 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.

After the division, we end up with 24114.833 and a remainder of 0.0004.
