28801530 ÷ 28 
We're looking to find how many times 28 goes into 28801530.

Let's proceed to step 1:
If we divide 2 by 28, we get 0 and a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 28

Going ahead to step 2:
When dividing 28 by 28, we get 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 0 after subtracting 28 from 28.
Bring next digit (8) of the dividend behind the 0 and repeat the process: 8 / 28

Step 3:
28 goes into 8 0 times with a remainder of 8.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtract 0 from 8 to get 8.
Fetch the next digit (0) from the dividend, attach it to 8 and continue: 80 / 28

On to step 4:
If we divide 80 by 28, we get 2 and a remainder of 24.
The next digit of our result is 2. 
Result so far: 102.0
Subtract 56 from 80 to get 24.
Append the next digit (1) from the dividend to 24 and continue with: 241 / 28

Going ahead to step 5:
If we divide 241 by 28, we get 8 and a remainder of 17.
Record the quotient 8 as the next digit in the result. 
Result so far: 1028.0
If we take 224 away from 241, we end up with 17.
Include the next digit (5) from the dividend after 17, then repeat: 175 / 28

Advancing to step 6:
The number 28 fits into 175 6 times, leaving a remainder of 7.
The next digit of our result is 6. 
Result so far: 10286.0
The remainder is 7 after subtracting 168 from 175.
Append the next digit (3) from the dividend to 7 and continue with: 73 / 28

Let's proceed to step 7:
The number 28 fits into 73 2 times, leaving a remainder of 17.
Use 2 as the next digit of our solution. 
Result so far: 102862.0
If we take 56 away from 73, we end up with 17.
Take the next digit (0) from the dividend and append it to 17, then repeat: 170 / 28

Going ahead to step 8:
170 divided by 28 is 6 with a remainder of 2.
Use 6 as the next digit of our solution. 
Result so far: 1028626.0
If we subtract 168 from 170, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 9:
The number 28 fits into 20 0 times, leaving a remainder of 20.
Write down 0 as next digit of the result. 
Result so far: 1028626.0
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 10:
When dividing 200 by 28, we get 7 with a remainder of 4.
Use 7 as the next digit of our solution. 
Result so far: 1028626.07
If we take 196 away from 200, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 11:
28 can be fit into 40 1 times, resulting in a remainder of 12.
The next digit of our result is 1. 
Result so far: 1028626.071
If we subtract 28 from 40, we get 12.
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 12:
120 divided by 28 is 4 with a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 1028626.0714
If we take 112 away from 120, we end up with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 13:
If we divide 80 by 28, we get 2 and a remainder of 24.
The next digit of our result is 2. 
Result so far: 1028626.07142
Subtracting 56 from 80 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 14:
When dividing 240 by 28, we get 8 with a remainder of 16.
Use 8 as the next digit of our solution. 
Result so far: 1028626.071428
The remainder is 16 after subtracting 224 from 240.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Moving on to step 15:
160 divided by 28 is 5 with a remainder of 20.
The number 5 becomes the next digit in our result. 
Result so far: 1028626.0714285
Deduct 140 from 160 and we're left 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.

On to step 16:
28 can be fit into 200 7 times, resulting in a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 1028626.07142857
If we subtract 196 from 200, we 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.

The final result is 1028626.07142857 with a remainder of 4e-09.
