69398911 ÷ 28 
Our goal is to divide 69398911 by 28.

Going ahead to step 1:
If we divide 6 by 28, we get 0 and a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 28

Moving on to step 2:
28 goes into 69 2 times with a remainder of 13.
Use 2 as the next digit of our solution. 
Result so far: 2.0
Deduct 56 from 69 and we're left with 13.
Include the next digit (3) from the dividend after 13, then repeat: 133 / 28

Step 3:
The number 28 fits into 133 4 times, leaving a remainder of 21.
The number 4 becomes the next digit in our result. 
Result so far: 24.0
Deduct 112 from 133 and we're left with 21.
Bring next digit (9) of the dividend behind the 21 and repeat the process: 219 / 28

Moving on to step 4:
If we divide 219 by 28, we get 7 and a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 247.0
Subtract 196 from 219 to get 23.
Append the next digit (8) from the dividend to 23 and continue with: 238 / 28

Step 5:
28 can be fit into 238 8 times, resulting in a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 2478.0
If we take 224 away from 238, we end up with 14.
Take the next digit (9) from the dividend and append it to 14, then repeat: 149 / 28

Advancing to step 6:
28 goes into 149 5 times with a remainder of 9.
Use 5 as the next digit of our solution. 
Result so far: 24785.0
Subtract 140 from 149 to get 9.
Bring next digit (1) of the dividend behind the 9 and repeat the process: 91 / 28

Moving on to step 7:
If we divide 91 by 28, we get 3 and a remainder of 7.
The next digit of our result is 3. 
Result so far: 247853.0
Deduct 84 from 91 and we're left with 7.
Bring next digit (1) of the dividend behind the 7 and repeat the process: 71 / 28

Let's proceed to step 8:
28 can be fit into 71 2 times, resulting in a remainder of 15.
Put 2 as the next digit of the answer. 
Result so far: 2478532.0
The remainder is 15 after subtracting 56 from 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Going ahead to step 9:
28 goes into 150 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 2478532.5
If we subtract 140 from 150, we 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.

Going ahead to step 10:
100 divided by 28 is 3 with a remainder of 16.
Record the quotient 3 as the next digit in the result. 
Result so far: 2478532.53
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 11:
If we divide 160 by 28, we get 5 and a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 2478532.535
If we take 140 away from 160, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 12:
If we divide 200 by 28, we get 7 and a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 2478532.5357
Subtract 196 from 200 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.

On to step 13:
28 can be fit into 40 1 times, resulting in a remainder of 12.
Write down 1 as next digit of the result. 
Result so far: 2478532.53571
The remainder is 12 after subtracting 28 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 14:
When dividing 120 by 28, we get 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 2478532.535714
The remainder is 8 after subtracting 112 from 120.
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 15:
80 divided by 28 is 2 with a remainder of 24.
The number 2 becomes the next digit in our result. 
Result so far: 2478532.5357142
The remainder is 24 after subtracting 56 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Moving on to step 16:
28 goes into 240 8 times with a remainder of 16.
The next digit of our result is 8. 
Result so far: 2478532.53571428
Subtract 224 from 240 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

The quotient of the division is 2478532.53571428, and the remainder is 1.6e-08.
