We're dividing 28817543 by 243 
Let's see how many times 243 fits into 28817543.

Let's proceed to step 1:
243 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
Subtracting 0 from 2 leaves us with 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 243

Step 2:
243 can be fit into 28 0 times, resulting in a remainder of 28.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 28, we end up with 28.
Fetch the next digit (8) from the dividend, attach it to 28 and continue: 288 / 243

Moving on to step 3:
243 can be fit into 288 1 times, resulting in a remainder of 45.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 243 from 288 and we're left with 45.
Fetch the next digit (1) from the dividend, attach it to 45 and continue: 451 / 243

Step 4:
When dividing 451 by 243, we get 1 with a remainder of 208.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Deduct 243 from 451 and we're left with 208.
Include the next digit (7) from the dividend after 208, then repeat: 2087 / 243

Going ahead to step 5:
The number 243 fits into 2087 8 times, leaving a remainder of 143.
The number 8 becomes the next digit in our result. 
Result so far: 118.0
Deduct 1944 from 2087 and we're left with 143.
Take the next digit (5) from the dividend and append it to 143, then repeat: 1435 / 243

Step 6:
243 can be fit into 1435 5 times, resulting in a remainder of 220.
Record the quotient 5 as the next digit in the result. 
Result so far: 1185.0
If we subtract 1215 from 1435, we get 220.
Grab the next digit (4) from the dividend, add it to 220, then carry on: 2204 / 243

Step 7:
2204 divided by 243 is 9 with a remainder of 17.
Write down 9 as next digit of the result. 
Result so far: 11859.0
Deduct 2187 from 2204 and we're left with 17.
Append the next digit (3) from the dividend to 17 and continue with: 173 / 243

On to step 8:
The number 243 fits into 173 0 times, leaving a remainder of 173.
Put 0 as the next digit of the answer. 
Result so far: 118590.0
The remainder is 173 after subtracting 0 from 173.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1730, and continue the process.

Advancing to step 9:
When dividing 1730 by 243, we get 7 with a remainder of 29.
Use 7 as the next digit of our solution. 
Result so far: 118590.7
If we take 1701 away from 1730, we end up with 29.
Since there are no more digits in the dividend, we add a zero to the remainder making it 290, and continue the process.

On to step 10:
243 goes into 290 1 times with a remainder of 47.
The next digit of our result is 1. 
Result so far: 118590.71
Deduct 243 from 290 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 11:
If we divide 470 by 243, we get 1 and a remainder of 227.
The number 1 becomes the next digit in our result. 
Result so far: 118590.711
Deduct 243 from 470 and we're left with 227.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2270, and continue the process.

The final outcome is 118590.711, with a leftover of 0.0227.
