28447820 ÷ 12 
We want to divide 28447820 by 12.

Step 1:
When dividing 2 by 12, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 12

Step 2:
The number 12 fits into 28 2 times, leaving a remainder of 4.
The next digit of our result is 2. 
Result so far: 2.0
Deduct 24 from 28 and we're left with 4.
Append the next digit (4) from the dividend to 4 and continue with: 44 / 12

Going ahead to step 3:
44 divided by 12 is 3 with a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 23.0
Subtract 36 from 44 to get 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 12

Moving on to step 4:
84 divided by 12 is 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 237.0
Subtracting 84 from 84 leaves us with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 12

Step 5:
12 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 2370.0
Subtracting 0 from 7 leaves us with 7.
Bring next digit (8) of the dividend behind the 7 and repeat the process: 78 / 12

Going ahead to step 6:
The number 12 fits into 78 6 times, leaving a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 23706.0
Deduct 72 from 78 and we're left with 6.
Append the next digit (2) from the dividend to 6 and continue with: 62 / 12

On to step 7:
12 can be fit into 62 5 times, resulting in a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 237065.0
Subtract 60 from 62 to get 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 12

Advancing to step 8:
When dividing 20 by 12, we get 1 with a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 2370651.0
The remainder is 8 after subtracting 12 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 9:
If we divide 80 by 12, we get 6 and a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 2370651.6
Subtract 72 from 80 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.

Going ahead to step 10:
12 can be fit into 80 6 times, resulting in a remainder of 8.
The next digit of our result is 6. 
Result so far: 2370651.66
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 quotient of the division is 2370651.66, and the remainder is 0.008.
