Let's divide 25728678 by 243
Let's see how many times 243 fits into 25728678.

Advancing to step 1:
243 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (5) from the dividend, attach it to 2 and continue: 25 / 243

Step 2:
The number 243 fits into 25 0 times, leaving a remainder of 25.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Grab the next digit (7) from the dividend, add it to 25, then carry on: 257 / 243

Step 3:
243 goes into 257 1 times with a remainder of 14.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 243 from 257 and we're left with 14.
Fetch the next digit (2) from the dividend, attach it to 14 and continue: 142 / 243

Advancing to step 4:
The number 243 fits into 142 0 times, leaving a remainder of 142.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we take 0 away from 142, we end up with 142.
Take the next digit (8) from the dividend and append it to 142, then repeat: 1428 / 243

Let's proceed to step 5:
243 can be fit into 1428 5 times, resulting in a remainder of 213.
Put 5 as the next digit of the answer. 
Result so far: 105.0
Deduct 1215 from 1428 and we're left with 213.
Fetch the next digit (6) from the dividend, attach it to 213 and continue: 2136 / 243

On to step 6:
243 can be fit into 2136 8 times, resulting in a remainder of 192.
Use 8 as the next digit of our solution. 
Result so far: 1058.0
The remainder is 192 after subtracting 1944 from 2136.
Bring next digit (7) of the dividend behind the 192 and repeat the process: 1927 / 243

On to step 7:
When dividing 1927 by 243, we get 7 with a remainder of 226.
Put 7 as the next digit of the answer. 
Result so far: 10587.0
If we subtract 1701 from 1927, we get 226.
Bring next digit (8) of the dividend behind the 226 and repeat the process: 2268 / 243

Going ahead to step 8:
2268 divided by 243 is 9 with a remainder of 81.
The next digit of our result is 9. 
Result so far: 105879.0
Subtract 2187 from 2268 to get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 9:
243 goes into 810 3 times with a remainder of 81.
The number 3 becomes the next digit in our result. 
Result so far: 105879.3
The remainder is 81 after subtracting 729 from 810.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Moving on to step 10:
The number 243 fits into 810 3 times, leaving a remainder of 81.
Use 3 as the next digit of our solution. 
Result so far: 105879.33
Subtracting 729 from 810 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Our division results in 105879.33 with a remaining 0.081.
