We're dividing 256854 by 51 
Our goal is to divide 256854 by 51.

Moving on to step 1:
When dividing 2 by 51, we get 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 51

Moving on to step 2:
When dividing 25 by 51, we get 0 with a remainder of 25.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 25 to get 25.
Fetch the next digit (6) from the dividend, attach it to 25 and continue: 256 / 51

Advancing to step 3:
The number 51 fits into 256 5 times, leaving a remainder of 1.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
If we subtract 255 from 256, we get 1.
Take the next digit (8) from the dividend and append it to 1, then repeat: 18 / 51

Going ahead to step 4:
The number 51 fits into 18 0 times, leaving a remainder of 18.
The next digit of our result is 0. 
Result so far: 50.0
Deduct 0 from 18 and we're left with 18.
Append the next digit (5) from the dividend to 18 and continue with: 185 / 51

Moving on to step 5:
51 goes into 185 3 times with a remainder of 32.
Write down 3 as next digit of the result. 
Result so far: 503.0
Subtracting 153 from 185 leaves us with 32.
Bring next digit (4) of the dividend behind the 32 and repeat the process: 324 / 51

Moving on to step 6:
When dividing 324 by 51, we get 6 with a remainder of 18.
Record the quotient 6 as the next digit in the result. 
Result so far: 5036.0
If we subtract 306 from 324, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 7:
51 can be fit into 180 3 times, resulting in a remainder of 27.
The next digit of our result is 3. 
Result so far: 5036.3
If we subtract 153 from 180, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 8:
When dividing 270 by 51, we get 5 with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 5036.35
If we subtract 255 from 270, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

On to step 9:
51 can be fit into 150 2 times, resulting in a remainder of 48.
Use 2 as the next digit of our solution. 
Result so far: 5036.352
Subtracting 102 from 150 leaves us with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 10:
51 can be fit into 480 9 times, resulting in a remainder of 21.
The number 9 becomes the next digit in our result. 
Result so far: 5036.3529
Subtract 459 from 480 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 11:
When dividing 210 by 51, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 5036.35294
If we subtract 204 from 210, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 12:
If we divide 60 by 51, we get 1 and a remainder of 9.
The next digit of our result is 1. 
Result so far: 5036.352941
Subtracting 51 from 60 leaves us with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Let's proceed to step 13:
51 goes into 90 1 times with a remainder of 39.
The number 1 becomes the next digit in our result. 
Result so far: 5036.3529411
Subtracting 51 from 90 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

The final result is 5036.3529411 with a remainder of 3.9e-07.
