256117 divided by 51 
Our goal is to divide 256117 by 51.

Step 1:
51 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.
Include the next digit (5) from the dividend after 2, then repeat: 25 / 51

Let's proceed to step 2:
51 goes into 25 0 times 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.
Append the next digit (6) from the dividend to 25 and continue with: 256 / 51

Advancing to step 3:
The number 51 fits into 256 5 times, leaving a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 5.0
The remainder is 1 after subtracting 255 from 256.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 51

Moving on to step 4:
If we divide 11 by 51, we get 0 and a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 50.0
The remainder is 11 after subtracting 0 from 11.
Include the next digit (1) from the dividend after 11, then repeat: 111 / 51

Moving on to step 5:
If we divide 111 by 51, we get 2 and a remainder of 9.
Record the quotient 2 as the next digit in the result. 
Result so far: 502.0
Subtracting 102 from 111 leaves us with 9.
Take the next digit (7) from the dividend and append it to 9, then repeat: 97 / 51

On to step 6:
The number 51 fits into 97 1 times, leaving a remainder of 46.
Write down 1 as next digit of the result. 
Result so far: 5021.0
If we subtract 51 from 97, we get 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Advancing to step 7:
When dividing 460 by 51, we get 9 with a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 5021.9
If we take 459 away from 460, 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.

Going ahead to step 8:
10 divided by 51 is 0 with a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 5021.9
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 9:
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: 5021.901
Deduct 51 from 100 and we're left 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.

Step 10:
490 divided by 51 is 9 with a remainder of 31.
Put 9 as the next digit of the answer. 
Result so far: 5021.9019
If we subtract 459 from 490, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Step 11:
The number 51 fits into 310 6 times, leaving a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 5021.90196
Subtract 306 from 310 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
51 can be fit into 40 0 times, resulting in a remainder of 40.
Put 0 as the next digit of the answer. 
Result so far: 5021.90196
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 13:
51 goes into 400 7 times with a remainder of 43.
Use 7 as the next digit of our solution. 
Result so far: 5021.9019607
If we subtract 357 from 400, we 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.

Let's proceed to step 14:
51 can be fit into 430 8 times, resulting in a remainder of 22.
Put 8 as the next digit of the answer. 
Result so far: 5021.90196078
Subtracting 408 from 430 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.

The final outcome is 5021.90196078, with a leftover of 2.2e-08.
