801388 ÷ 28 
We're looking to find how many times 28 goes into 801388.

Going ahead to step 1:
28 can be fit into 8 0 times, resulting in a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (0) from the dividend and append it to 8, then repeat: 80 / 28

Advancing to step 2:
If we divide 80 by 28, we get 2 and a remainder of 24.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 56 away from 80, we end up with 24.
Append the next digit (1) from the dividend to 24 and continue with: 241 / 28

Going ahead to step 3:
241 divided by 28 is 8 with a remainder of 17.
Record the quotient 8 as the next digit in the result. 
Result so far: 28.0
Deduct 224 from 241 and we're left with 17.
Bring next digit (3) of the dividend behind the 17 and repeat the process: 173 / 28

Let's proceed to step 4:
28 can be fit into 173 6 times, resulting in a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 286.0
The remainder is 5 after subtracting 168 from 173.
Take the next digit (8) from the dividend and append it to 5, then repeat: 58 / 28

On to step 5:
When dividing 58 by 28, we get 2 with a remainder of 2.
Use 2 as the next digit of our solution. 
Result so far: 2862.0
If we take 56 away from 58, we end up with 2.
Bring next digit (8) of the dividend behind the 2 and repeat the process: 28 / 28

Step 6:
When dividing 28 by 28, we get 1 with a remainder of 0.
The next digit of our result is 1. 
Result so far: 28621.0
The remainder is 0 after subtracting 28 from 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Let's proceed to step 7:
28 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 28621.0
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.

On to step 8:
When dividing 0 by 28, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 28621.0
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.

After the division, we end up with 28621.0 and a remainder of 0.0.
