84223398 ÷ 28 
Our goal is to divide 84223398 by 28.

Let's proceed to step 1:
28 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (4) of the dividend behind the 8 and repeat the process: 84 / 28

Moving on to step 2:
When dividing 84 by 28, we get 3 with a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
Subtract 84 from 84 to get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 28

On to step 3:
28 goes into 2 0 times with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 30.0
If we subtract 0 from 2, we get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 28

Moving on to step 4:
28 goes into 22 0 times with a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 300.0
Subtracting 0 from 22 leaves us with 22.
Fetch the next digit (3) from the dividend, attach it to 22 and continue: 223 / 28

Going ahead to step 5:
28 goes into 223 7 times with a remainder of 27.
Use 7 as the next digit of our solution. 
Result so far: 3007.0
If we subtract 196 from 223, we get 27.
Include the next digit (3) from the dividend after 27, then repeat: 273 / 28

Going ahead to step 6:
28 can be fit into 273 9 times, resulting in a remainder of 21.
Use 9 as the next digit of our solution. 
Result so far: 30079.0
If we take 252 away from 273, we end up with 21.
Grab the next digit (9) from the dividend, add it to 21, then carry on: 219 / 28

Going ahead to step 7:
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: 300797.0
The remainder is 23 after subtracting 196 from 219.
Bring next digit (8) of the dividend behind the 23 and repeat the process: 238 / 28

Moving on to step 8:
The number 28 fits into 238 8 times, leaving a remainder of 14.
The number 8 becomes the next digit in our result. 
Result so far: 3007978.0
Subtract 224 from 238 to get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

On to step 9:
28 goes into 140 5 times with a remainder of 0.
The next digit of our result is 5. 
Result so far: 3007978.5
Deduct 140 from 140 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 10:
28 can be fit into 0 0 times, resulting in a remainder of 0.
The next digit of our result is 0. 
Result so far: 3007978.5
Subtract 0 from 0 to get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 11:
0 divided by 28 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 3007978.5
If we subtract 0 from 0, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Our division results in 3007978.5 with a remaining 0.0.
