We look at the division of 28308686 by 488 
We want to figure out the number of times 28308686 can be divided by 488.

On to step 1:
488 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 488

Moving on to step 2:
28 divided by 488 is 0 with a remainder of 28.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Fetch the next digit (3) from the dividend, attach it to 28 and continue: 283 / 488

On to step 3:
488 can be fit into 283 0 times, resulting in a remainder of 283.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 283 leaves us with 283.
Bring next digit (0) of the dividend behind the 283 and repeat the process: 2830 / 488

Advancing to step 4:
2830 divided by 488 is 5 with a remainder of 390.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 2440 away from 2830, we end up with 390.
Bring next digit (8) of the dividend behind the 390 and repeat the process: 3908 / 488

Advancing to step 5:
488 can be fit into 3908 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 58.0
Subtract 3904 from 3908 to get 4.
Take the next digit (6) from the dividend and append it to 4, then repeat: 46 / 488

Moving on to step 6:
488 goes into 46 0 times with a remainder of 46.
The next digit of our result is 0. 
Result so far: 580.0
Subtracting 0 from 46 leaves us with 46.
Fetch the next digit (8) from the dividend, attach it to 46 and continue: 468 / 488

Going ahead to step 7:
If we divide 468 by 488, we get 0 and a remainder of 468.
Write down 0 as next digit of the result. 
Result so far: 5800.0
Deduct 0 from 468 and we're left with 468.
Bring next digit (6) of the dividend behind the 468 and repeat the process: 4686 / 488

Moving on to step 8:
The number 488 fits into 4686 9 times, leaving a remainder of 294.
The number 9 becomes the next digit in our result. 
Result so far: 58009.0
Deduct 4392 from 4686 and we're left with 294.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2940, and continue the process.

On to step 9:
488 goes into 2940 6 times with a remainder of 12.
Put 6 as the next digit of the answer. 
Result so far: 58009.6
If we take 2928 away from 2940, we end up with 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 10:
When dividing 120 by 488, we get 0 with a remainder of 120.
The next digit of our result is 0. 
Result so far: 58009.6
Subtract 0 from 120 to get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 11:
When dividing 1200 by 488, we get 2 with a remainder of 224.
Record the quotient 2 as the next digit in the result. 
Result so far: 58009.602
If we take 976 away from 1200, we end up with 224.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2240, and continue the process.

Moving on to step 12:
If we divide 2240 by 488, we get 4 and a remainder of 288.
The number 4 becomes the next digit in our result. 
Result so far: 58009.6024
If we take 1952 away from 2240, we end up with 288.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2880, and continue the process.

Let's proceed to step 13:
488 goes into 2880 5 times with a remainder of 440.
The number 5 becomes the next digit in our result. 
Result so far: 58009.60245
The remainder is 440 after subtracting 2440 from 2880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4400, and continue the process.

Advancing to step 14:
488 goes into 4400 9 times with a remainder of 8.
The next digit of our result is 9. 
Result so far: 58009.602459
Subtract 4392 from 4400 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 15:
488 goes into 80 0 times with a remainder of 80.
The number 0 becomes the next digit in our result. 
Result so far: 58009.602459
If we take 0 away from 80, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Going ahead to step 16:
800 divided by 488 is 1 with a remainder of 312.
The number 1 becomes the next digit in our result. 
Result so far: 58009.60245901
Deduct 488 from 800 and we're left with 312.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3120, and continue the process.

The final result is 58009.60245901 with a remainder of 3.12e-07.
