We're dividing 12880608 by 424 
We want to divide 12880608 by 424.

Step 1:
If we divide 1 by 424, we get 0 and a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Take the next digit (2) from the dividend and append it to 1, then repeat: 12 / 424

Let's proceed to step 2:
12 divided by 424 is 0 with a remainder of 12.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 12, we end up with 12.
Include the next digit (8) from the dividend after 12, then repeat: 128 / 424

Moving on to step 3:
128 divided by 424 is 0 with a remainder of 128.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 128 and we're left with 128.
Append the next digit (8) from the dividend to 128 and continue with: 1288 / 424

Step 4:
1288 divided by 424 is 3 with a remainder of 16.
Use 3 as the next digit of our solution. 
Result so far: 3.0
The remainder is 16 after subtracting 1272 from 1288.
Include the next digit (0) from the dividend after 16, then repeat: 160 / 424

Advancing to step 5:
160 divided by 424 is 0 with a remainder of 160.
The number 0 becomes the next digit in our result. 
Result so far: 30.0
The remainder is 160 after subtracting 0 from 160.
Append the next digit (6) from the dividend to 160 and continue with: 1606 / 424

Going ahead to step 6:
If we divide 1606 by 424, we get 3 and a remainder of 334.
The number 3 becomes the next digit in our result. 
Result so far: 303.0
Subtracting 1272 from 1606 leaves us with 334.
Take the next digit (0) from the dividend and append it to 334, then repeat: 3340 / 424

On to step 7:
424 can be fit into 3340 7 times, resulting in a remainder of 372.
Put 7 as the next digit of the answer. 
Result so far: 3037.0
If we subtract 2968 from 3340, we get 372.
Append the next digit (8) from the dividend to 372 and continue with: 3728 / 424

Going ahead to step 8:
The number 424 fits into 3728 8 times, leaving a remainder of 336.
Record the quotient 8 as the next digit in the result. 
Result so far: 30378.0
The remainder is 336 after subtracting 3392 from 3728.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3360, and continue the process.

Going ahead to step 9:
If we divide 3360 by 424, we get 7 and a remainder of 392.
The next digit of our result is 7. 
Result so far: 30378.7
If we take 2968 away from 3360, we end up with 392.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3920, and continue the process.

Moving on to step 10:
424 can be fit into 3920 9 times, resulting in a remainder of 104.
Record the quotient 9 as the next digit in the result. 
Result so far: 30378.79
If we subtract 3816 from 3920, we get 104.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1040, and continue the process.

Step 11:
424 can be fit into 1040 2 times, resulting in a remainder of 192.
Use 2 as the next digit of our solution. 
Result so far: 30378.792
Deduct 848 from 1040 and we're left with 192.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1920, and continue the process.

Step 12:
424 goes into 1920 4 times with a remainder of 224.
Put 4 as the next digit of the answer. 
Result so far: 30378.7924
Subtracting 1696 from 1920 leaves us with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Going ahead to step 13:
When dividing 2240 by 424, we get 5 with a remainder of 120.
Put 5 as the next digit of the answer. 
Result so far: 30378.79245
If we take 2120 away from 2240, we end up with 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 14:
If we divide 1200 by 424, we get 2 and a remainder of 352.
Record the quotient 2 as the next digit in the result. 
Result so far: 30378.792452
Subtract 848 from 1200 to get 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 15:
If we divide 3520 by 424, we get 8 and a remainder of 128.
The number 8 becomes the next digit in our result. 
Result so far: 30378.7924528
If we subtract 3392 from 3520, we get 128.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1280, and continue the process.

Let's proceed to step 16:
The number 424 fits into 1280 3 times, leaving a remainder of 8.
Write down 3 as next digit of the result. 
Result so far: 30378.79245283
The remainder is 8 after subtracting 1272 from 1280.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

After the division, we end up with 30378.79245283 and a remainder of 8e-09.
