We look at the division of 28664147 by 215 
We want to divide 28664147 by 215.

On to step 1:
The number 215 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Fetch the next digit (8) from the dividend, attach it to 2 and continue: 28 / 215

Advancing to step 2:
215 goes into 28 0 times with a remainder of 28.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 28 after subtracting 0 from 28.
Take the next digit (6) from the dividend and append it to 28, then repeat: 286 / 215

Moving on to step 3:
If we divide 286 by 215, we get 1 and a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 215 from 286 to get 71.
Bring next digit (6) of the dividend behind the 71 and repeat the process: 716 / 215

On to step 4:
716 divided by 215 is 3 with a remainder of 71.
The number 3 becomes the next digit in our result. 
Result so far: 13.0
If we subtract 645 from 716, we get 71.
Append the next digit (4) from the dividend to 71 and continue with: 714 / 215

Advancing to step 5:
215 goes into 714 3 times with a remainder of 69.
The next digit of our result is 3. 
Result so far: 133.0
If we take 645 away from 714, we end up with 69.
Append the next digit (1) from the dividend to 69 and continue with: 691 / 215

Advancing to step 6:
215 can be fit into 691 3 times, resulting in a remainder of 46.
Use 3 as the next digit of our solution. 
Result so far: 1333.0
The remainder is 46 after subtracting 645 from 691.
Fetch the next digit (4) from the dividend, attach it to 46 and continue: 464 / 215

Advancing to step 7:
If we divide 464 by 215, we get 2 and a remainder of 34.
The next digit of our result is 2. 
Result so far: 13332.0
Subtracting 430 from 464 leaves us with 34.
Fetch the next digit (7) from the dividend, attach it to 34 and continue: 347 / 215

Advancing to step 8:
The number 215 fits into 347 1 times, leaving a remainder of 132.
The number 1 becomes the next digit in our result. 
Result so far: 133321.0
If we take 215 away from 347, we end up with 132.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1320, and continue the process.

Going ahead to step 9:
When dividing 1320 by 215, we get 6 with a remainder of 30.
Write down 6 as next digit of the result. 
Result so far: 133321.6
Subtracting 1290 from 1320 leaves us with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 10:
215 can be fit into 300 1 times, resulting in a remainder of 85.
Put 1 as the next digit of the answer. 
Result so far: 133321.61
The remainder is 85 after subtracting 215 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 850, and continue the process.

Moving on to step 11:
The number 215 fits into 850 3 times, leaving a remainder of 205.
Write down 3 as next digit of the result. 
Result so far: 133321.613
The remainder is 205 after subtracting 645 from 850.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2050, and continue the process.

Moving on to step 12:
The number 215 fits into 2050 9 times, leaving a remainder of 115.
Put 9 as the next digit of the answer. 
Result so far: 133321.6139
If we subtract 1935 from 2050, we get 115.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1150, and continue the process.

Step 13:
When dividing 1150 by 215, we get 5 with a remainder of 75.
Use 5 as the next digit of our solution. 
Result so far: 133321.61395
Subtracting 1075 from 1150 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Let's proceed to step 14:
The number 215 fits into 750 3 times, leaving a remainder of 105.
Use 3 as the next digit of our solution. 
Result so far: 133321.613953
If we subtract 645 from 750, we get 105.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1050, and continue the process.

Going ahead to step 15:
215 can be fit into 1050 4 times, resulting in a remainder of 190.
Use 4 as the next digit of our solution. 
Result so far: 133321.6139534
Deduct 860 from 1050 and we're left with 190.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1900, and continue the process.

Going ahead to step 16:
If we divide 1900 by 215, we get 8 and a remainder of 180.
The next digit of our result is 8. 
Result so far: 133321.61395348
Subtracting 1720 from 1900 leaves us with 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1800, and continue the process.

After the division, we end up with 133321.61395348 and a remainder of 1.8e-07.
