245857 ÷ 51 
We want to divide 245857 by 51.

On to step 1:
51 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (4) from the dividend after 2, then repeat: 24 / 51

Moving on to step 2:
If we divide 24 by 51, we get 0 and a remainder of 24.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 24 leaves us with 24.
Take the next digit (5) from the dividend and append it to 24, then repeat: 245 / 51

On to step 3:
When dividing 245 by 51, we get 4 with a remainder of 41.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 204 away from 245, we end up with 41.
Grab the next digit (8) from the dividend, add it to 41, then carry on: 418 / 51

Going ahead to step 4:
51 goes into 418 8 times with a remainder of 10.
Write down 8 as next digit of the result. 
Result so far: 48.0
Subtracting 408 from 418 leaves us with 10.
Bring next digit (5) of the dividend behind the 10 and repeat the process: 105 / 51

Moving on to step 5:
51 can be fit into 105 2 times, resulting in a remainder of 3.
Put 2 as the next digit of the answer. 
Result so far: 482.0
Subtract 102 from 105 to get 3.
Append the next digit (7) from the dividend to 3 and continue with: 37 / 51

On to step 6:
37 divided by 51 is 0 with a remainder of 37.
The number 0 becomes the next digit in our result. 
Result so far: 4820.0
If we take 0 away from 37, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Going ahead to step 7:
If we divide 370 by 51, we get 7 and a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 4820.7
Subtracting 357 from 370 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Moving on to step 8:
130 divided by 51 is 2 with a remainder of 28.
Record the quotient 2 as the next digit in the result. 
Result so far: 4820.72
The remainder is 28 after subtracting 102 from 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 280, and continue the process.

Let's proceed to step 9:
If we divide 280 by 51, we get 5 and a remainder of 25.
The next digit of our result is 5. 
Result so far: 4820.725
Deduct 255 from 280 and we're left with 25.
Since there are no more digits in the dividend, we add a zero to the remainder making it 250, and continue the process.

Going ahead to step 10:
When dividing 250 by 51, we get 4 with a remainder of 46.
The next digit of our result is 4. 
Result so far: 4820.7254
The remainder is 46 after subtracting 204 from 250.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

On to step 11:
51 can be fit into 460 9 times, resulting in a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 4820.72549
Deduct 459 from 460 and we're left with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 12:
51 can be fit into 10 0 times, resulting in a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 4820.72549
Subtracting 0 from 10 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 13:
The number 51 fits into 100 1 times, leaving a remainder of 49.
Write down 1 as next digit of the result. 
Result so far: 4820.7254901
The remainder is 49 after subtracting 51 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 14:
If we divide 490 by 51, we get 9 and a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 4820.72549019
Deduct 459 from 490 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The final result is 4820.72549019 with a remainder of 3.1e-08.
