28069387 divided by 428 
Our goal is to divide 28069387 by 428.

On to step 1:
428 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 428

Going ahead to step 2:
When dividing 28 by 428, we get 0 with a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 28 to get 28.
Grab the next digit (0) from the dividend, add it to 28, then carry on: 280 / 428

Let's proceed to step 3:
When dividing 280 by 428, we get 0 with a remainder of 280.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 280, we get 280.
Take the next digit (6) from the dividend and append it to 280, then repeat: 2806 / 428

Advancing to step 4:
428 can be fit into 2806 6 times, resulting in a remainder of 238.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 2568 away from 2806, we end up with 238.
Grab the next digit (9) from the dividend, add it to 238, then carry on: 2389 / 428

On to step 5:
428 goes into 2389 5 times with a remainder of 249.
Put 5 as the next digit of the answer. 
Result so far: 65.0
Subtracting 2140 from 2389 leaves us with 249.
Include the next digit (3) from the dividend after 249, then repeat: 2493 / 428

Let's proceed to step 6:
The number 428 fits into 2493 5 times, leaving a remainder of 353.
Put 5 as the next digit of the answer. 
Result so far: 655.0
Subtract 2140 from 2493 to get 353.
Fetch the next digit (8) from the dividend, attach it to 353 and continue: 3538 / 428

Going ahead to step 7:
When dividing 3538 by 428, we get 8 with a remainder of 114.
The number 8 becomes the next digit in our result. 
Result so far: 6558.0
If we take 3424 away from 3538, we end up with 114.
Take the next digit (7) from the dividend and append it to 114, then repeat: 1147 / 428

Advancing to step 8:
1147 divided by 428 is 2 with a remainder of 291.
The number 2 becomes the next digit in our result. 
Result so far: 65582.0
Subtract 856 from 1147 to get 291.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2910, and continue the process.

Step 9:
If we divide 2910 by 428, we get 6 and a remainder of 342.
The next digit of our result is 6. 
Result so far: 65582.6
Deduct 2568 from 2910 and we're left with 342.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3420, and continue the process.

Step 10:
428 goes into 3420 7 times with a remainder of 424.
Use 7 as the next digit of our solution. 
Result so far: 65582.67
Subtracting 2996 from 3420 leaves us with 424.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4240, and continue the process.

Going ahead to step 11:
428 goes into 4240 9 times with a remainder of 388.
The next digit of our result is 9. 
Result so far: 65582.679
If we subtract 3852 from 4240, we get 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

On to step 12:
When dividing 3880 by 428, we get 9 with a remainder of 28.
Write down 9 as next digit of the result. 
Result so far: 65582.6799
The remainder is 28 after subtracting 3852 from 3880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

After the division, we end up with 65582.6799 and a remainder of 0.00028.
