Let's divide 80530807 by 28
Our goal is to divide 80530807 by 28.

Advancing to step 1:
28 goes into 8 0 times with a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 28

Going ahead to step 2:
If we divide 80 by 28, we get 2 and a remainder of 24.
Use 2 as the next digit of our solution. 
Result so far: 2.0
If we take 56 away from 80, we end up with 24.
Append the next digit (5) from the dividend to 24 and continue with: 245 / 28

Step 3:
The number 28 fits into 245 8 times, leaving a remainder of 21.
The number 8 becomes the next digit in our result. 
Result so far: 28.0
Deduct 224 from 245 and we're left with 21.
Grab the next digit (3) from the dividend, add it to 21, then carry on: 213 / 28

Let's proceed to step 4:
213 divided by 28 is 7 with a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 287.0
If we subtract 196 from 213, we get 17.
Grab the next digit (0) from the dividend, add it to 17, then carry on: 170 / 28

On to step 5:
When dividing 170 by 28, we get 6 with a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 2876.0
Subtract 168 from 170 to get 2.
Grab the next digit (8) from the dividend, add it to 2, then carry on: 28 / 28

Let's proceed to step 6:
The number 28 fits into 28 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 28761.0
If we take 28 away from 28, we end up with 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 28

Going ahead to step 7:
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: 287610.0
If we subtract 0 from 0, we get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 28

On to step 8:
When dividing 7 by 28, we get 0 with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 2876100.0
Deduct 0 from 7 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Advancing to step 9:
When dividing 70 by 28, we get 2 with a remainder of 14.
Use 2 as the next digit of our solution. 
Result so far: 2876100.2
Subtract 56 from 70 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.

Going ahead to step 10:
When dividing 140 by 28, we get 5 with a remainder of 0.
The next digit of our result is 5. 
Result so far: 2876100.25
If we take 140 away from 140, we end up 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 11:
28 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2876100.25
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.

Step 12:
The number 28 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2876100.25
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.

The quotient of the division is 2876100.25, and the remainder is 0.0.
