We look at the division of 57816456 by 263 
We're looking to find how many times 263 goes into 57816456.

Advancing to step 1:
263 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 263

Going ahead to step 2:
263 goes into 57 0 times with a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 57 leaves us with 57.
Include the next digit (8) from the dividend after 57, then repeat: 578 / 263

On to step 3:
263 can be fit into 578 2 times, resulting in a remainder of 52.
Write down 2 as next digit of the result. 
Result so far: 2.0
Deduct 526 from 578 and we're left with 52.
Append the next digit (1) from the dividend to 52 and continue with: 521 / 263

Going ahead to step 4:
When dividing 521 by 263, we get 1 with a remainder of 258.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we take 263 away from 521, we end up with 258.
Bring next digit (6) of the dividend behind the 258 and repeat the process: 2586 / 263

Moving on to step 5:
The number 263 fits into 2586 9 times, leaving a remainder of 219.
The next digit of our result is 9. 
Result so far: 219.0
Deduct 2367 from 2586 and we're left with 219.
Append the next digit (4) from the dividend to 219 and continue with: 2194 / 263

Step 6:
2194 divided by 263 is 8 with a remainder of 90.
Write down 8 as next digit of the result. 
Result so far: 2198.0
Subtracting 2104 from 2194 leaves us with 90.
Take the next digit (5) from the dividend and append it to 90, then repeat: 905 / 263

Let's proceed to step 7:
263 goes into 905 3 times with a remainder of 116.
Put 3 as the next digit of the answer. 
Result so far: 21983.0
Deduct 789 from 905 and we're left with 116.
Include the next digit (6) from the dividend after 116, then repeat: 1166 / 263

Let's proceed to step 8:
263 goes into 1166 4 times with a remainder of 114.
Write down 4 as next digit of the result. 
Result so far: 219834.0
If we take 1052 away from 1166, we end up with 114.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1140, and continue the process.

Moving on to step 9:
1140 divided by 263 is 4 with a remainder of 88.
Use 4 as the next digit of our solution. 
Result so far: 219834.4
If we subtract 1052 from 1140, we get 88.
Since there are no more digits in the dividend, we add a zero to the remainder making it 880, and continue the process.

Advancing to step 10:
880 divided by 263 is 3 with a remainder of 91.
Use 3 as the next digit of our solution. 
Result so far: 219834.43
Subtracting 789 from 880 leaves us with 91.
Since there are no more digits in the dividend, we add a zero to the remainder making it 910, and continue the process.

On to step 11:
910 divided by 263 is 3 with a remainder of 121.
Use 3 as the next digit of our solution. 
Result so far: 219834.433
Subtract 789 from 910 to get 121.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1210, and continue the process.

The final result is 219834.433 with a remainder of 0.0121.
