278573 divided by 12 
Let's see how many times 12 fits into 278573.

Advancing to step 1:
When dividing 2 by 12, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 12

Moving on to step 2:
If we divide 27 by 12, we get 2 and a remainder of 3.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 24 away from 27, we end up with 3.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 12

On to step 3:
12 can be fit into 38 3 times, resulting in a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 23.0
Deduct 36 from 38 and we're left with 2.
Bring next digit (5) of the dividend behind the 2 and repeat the process: 25 / 12

Moving on to step 4:
If we divide 25 by 12, we get 2 and a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 232.0
Subtracting 24 from 25 leaves us with 1.
Take the next digit (7) from the dividend and append it to 1, then repeat: 17 / 12

On to step 5:
17 divided by 12 is 1 with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 2321.0
The remainder is 5 after subtracting 12 from 17.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 12

Let's proceed to step 6:
When dividing 53 by 12, we get 4 with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 23214.0
Deduct 48 from 53 and we're left with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Step 7:
The number 12 fits into 50 4 times, leaving a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 23214.4
Deduct 48 from 50 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 8:
If we divide 20 by 12, we get 1 and a remainder of 8.
Write down 1 as next digit of the result. 
Result so far: 23214.41
Subtract 12 from 20 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
If we divide 80 by 12, we get 6 and a remainder of 8.
The number 6 becomes the next digit in our result. 
Result so far: 23214.416
The remainder is 8 after subtracting 72 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
When dividing 80 by 12, we get 6 with a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 23214.4166
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final result is 23214.4166 with a remainder of 8e-05.
