We look at the division of 256843 by 57 
Let's see how many times 57 fits into 256843.

Advancing to step 1:
57 goes into 2 0 times with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 57

Moving on to step 2:
57 can be fit into 25 0 times, resulting in a remainder of 25.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 25 after subtracting 0 from 25.
Fetch the next digit (6) from the dividend, attach it to 25 and continue: 256 / 57

Let's proceed to step 3:
57 goes into 256 4 times with a remainder of 28.
Use 4 as the next digit of our solution. 
Result so far: 4.0
The remainder is 28 after subtracting 228 from 256.
Fetch the next digit (8) from the dividend, attach it to 28 and continue: 288 / 57

Advancing to step 4:
When dividing 288 by 57, we get 5 with a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 45.0
Subtracting 285 from 288 leaves us with 3.
Take the next digit (4) from the dividend and append it to 3, then repeat: 34 / 57

Moving on to step 5:
57 can be fit into 34 0 times, resulting in a remainder of 34.
The number 0 becomes the next digit in our result. 
Result so far: 450.0
If we take 0 away from 34, we end up with 34.
Grab the next digit (3) from the dividend, add it to 34, then carry on: 343 / 57

Step 6:
The number 57 fits into 343 6 times, leaving a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 4506.0
If we take 342 away from 343, we end up 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.

On to step 7:
57 goes into 10 0 times with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 4506.0
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 8:
If we divide 100 by 57, we get 1 and a remainder of 43.
Put 1 as the next digit of the answer. 
Result so far: 4506.01
Subtract 57 from 100 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 9:
430 divided by 57 is 7 with a remainder of 31.
The next digit of our result is 7. 
Result so far: 4506.017
Subtracting 399 from 430 leaves us 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.

On to step 10:
310 divided by 57 is 5 with a remainder of 25.
Use 5 as the next digit of our solution. 
Result so far: 4506.0175
Subtract 285 from 310 to get 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 11:
When dividing 250 by 57, we get 4 with a remainder of 22.
Put 4 as the next digit of the answer. 
Result so far: 4506.01754
Subtracting 228 from 250 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 12:
220 divided by 57 is 3 with a remainder of 49.
The number 3 becomes the next digit in our result. 
Result so far: 4506.017543
If we take 171 away from 220, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Advancing to step 13:
The number 57 fits into 490 8 times, leaving a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 4506.0175438
Subtracting 456 from 490 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 14:
57 goes into 340 5 times with a remainder of 55.
Put 5 as the next digit of the answer. 
Result so far: 4506.01754385
If we subtract 285 from 340, we get 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

The final outcome is 4506.01754385, with a leftover of 5.5e-08.
