We look at the division of 28578812 by 243 
Let's see how many times 243 fits into 28578812.

Let's proceed to step 1:
When dividing 2 by 243, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 243

Moving on to step 2:
28 divided by 243 is 0 with a remainder of 28.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Include the next digit (5) from the dividend after 28, then repeat: 285 / 243

Step 3:
The number 243 fits into 285 1 times, leaving a remainder of 42.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 243 from 285, we get 42.
Append the next digit (7) from the dividend to 42 and continue with: 427 / 243

On to step 4:
243 goes into 427 1 times with a remainder of 184.
Use 1 as the next digit of our solution. 
Result so far: 11.0
The remainder is 184 after subtracting 243 from 427.
Include the next digit (8) from the dividend after 184, then repeat: 1848 / 243

Advancing to step 5:
The number 243 fits into 1848 7 times, leaving a remainder of 147.
Write down 7 as next digit of the result. 
Result so far: 117.0
If we take 1701 away from 1848, we end up with 147.
Include the next digit (8) from the dividend after 147, then repeat: 1478 / 243

Going ahead to step 6:
1478 divided by 243 is 6 with a remainder of 20.
The number 6 becomes the next digit in our result. 
Result so far: 1176.0
Subtract 1458 from 1478 to get 20.
Fetch the next digit (1) from the dividend, attach it to 20 and continue: 201 / 243

Advancing to step 7:
201 divided by 243 is 0 with a remainder of 201.
The next digit of our result is 0. 
Result so far: 11760.0
Subtracting 0 from 201 leaves us with 201.
Fetch the next digit (2) from the dividend, attach it to 201 and continue: 2012 / 243

Moving on to step 8:
243 goes into 2012 8 times with a remainder of 68.
Write down 8 as next digit of the result. 
Result so far: 117608.0
Subtract 1944 from 2012 to get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 9:
243 goes into 680 2 times with a remainder of 194.
Write down 2 as next digit of the result. 
Result so far: 117608.2
Deduct 486 from 680 and we're left with 194.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1940, and continue the process.

Let's proceed to step 10:
1940 divided by 243 is 7 with a remainder of 239.
Put 7 as the next digit of the answer. 
Result so far: 117608.27
If we subtract 1701 from 1940, we get 239.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2390, and continue the process.

Step 11:
243 can be fit into 2390 9 times, resulting in a remainder of 203.
Use 9 as the next digit of our solution. 
Result so far: 117608.279
Subtracting 2187 from 2390 leaves us with 203.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Advancing to step 12:
243 goes into 2030 8 times with a remainder of 86.
The next digit of our result is 8. 
Result so far: 117608.2798
Subtracting 1944 from 2030 leaves us with 86.
Since there are no more digits in the dividend, we add a zero to the remainder making it 860, and continue the process.

On to step 13:
243 can be fit into 860 3 times, resulting in a remainder of 131.
The number 3 becomes the next digit in our result. 
Result so far: 117608.27983
The remainder is 131 after subtracting 729 from 860.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1310, and continue the process.

Advancing to step 14:
243 can be fit into 1310 5 times, resulting in a remainder of 95.
Write down 5 as next digit of the result. 
Result so far: 117608.279835
If we subtract 1215 from 1310, we get 95.
Since there are no more digits in the dividend, we add a zero to the remainder making it 950, and continue the process.

Going ahead to step 15:
If we divide 950 by 243, we get 3 and a remainder of 221.
Record the quotient 3 as the next digit in the result. 
Result so far: 117608.2798353
If we take 729 away from 950, we end up with 221.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2210, and continue the process.

Advancing to step 16:
243 can be fit into 2210 9 times, resulting in a remainder of 23.
The next digit of our result is 9. 
Result so far: 117608.27983539
Subtracting 2187 from 2210 leaves us with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Our division results in 117608.27983539 with a remaining 2.3e-08.
