248393 divided by 57 
We want to figure out the number of times 248393 can be divided by 57.

Going ahead to step 1:
When dividing 2 by 57, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 57

On to step 2:
The number 57 fits into 24 0 times, leaving a remainder of 24.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 24 to get 24.
Include the next digit (8) from the dividend after 24, then repeat: 248 / 57

Advancing to step 3:
If we divide 248 by 57, we get 4 and a remainder of 20.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 228 from 248 leaves us with 20.
Fetch the next digit (3) from the dividend, attach it to 20 and continue: 203 / 57

Moving on to step 4:
57 can be fit into 203 3 times, resulting in a remainder of 32.
Put 3 as the next digit of the answer. 
Result so far: 43.0
If we take 171 away from 203, we end up with 32.
Include the next digit (9) from the dividend after 32, then repeat: 329 / 57

On to step 5:
57 goes into 329 5 times with a remainder of 44.
Record the quotient 5 as the next digit in the result. 
Result so far: 435.0
Deduct 285 from 329 and we're left with 44.
Fetch the next digit (3) from the dividend, attach it to 44 and continue: 443 / 57

On to step 6:
If we divide 443 by 57, we get 7 and a remainder of 44.
The number 7 becomes the next digit in our result. 
Result so far: 4357.0
If we subtract 399 from 443, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

On to step 7:
440 divided by 57 is 7 with a remainder of 41.
Record the quotient 7 as the next digit in the result. 
Result so far: 4357.7
The remainder is 41 after subtracting 399 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 410, and continue the process.

On to step 8:
If we divide 410 by 57, we get 7 and a remainder of 11.
Use 7 as the next digit of our solution. 
Result so far: 4357.77
The remainder is 11 after subtracting 399 from 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

In conclusion, the division gives 4357.77 with a balance of 0.011.
