We look at the division of 270391 by 51 
We want to figure out the number of times 270391 can be divided by 51.

Going ahead to step 1:
51 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 51

Advancing to step 2:
The number 51 fits into 27 0 times, leaving a remainder of 27.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 27 and we're left with 27.
Include the next digit (0) from the dividend after 27, then repeat: 270 / 51

Step 3:
When dividing 270 by 51, we get 5 with a remainder of 15.
The number 5 becomes the next digit in our result. 
Result so far: 5.0
The remainder is 15 after subtracting 255 from 270.
Append the next digit (3) from the dividend to 15 and continue with: 153 / 51

Moving on to step 4:
The number 51 fits into 153 3 times, leaving a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 53.0
The remainder is 0 after subtracting 153 from 153.
Take the next digit (9) from the dividend and append it to 0, then repeat: 9 / 51

On to step 5:
When dividing 9 by 51, we get 0 with a remainder of 9.
Put 0 as the next digit of the answer. 
Result so far: 530.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (1) from the dividend, add it to 9, then carry on: 91 / 51

Going ahead to step 6:
The number 51 fits into 91 1 times, leaving a remainder of 40.
Use 1 as the next digit of our solution. 
Result so far: 5301.0
Subtracting 51 from 91 leaves us with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Let's proceed to step 7:
51 goes into 400 7 times with a remainder of 43.
The number 7 becomes the next digit in our result. 
Result so far: 5301.7
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.

Step 8:
51 can be fit into 430 8 times, resulting in a remainder of 22.
Record the quotient 8 as the next digit in the result. 
Result so far: 5301.78
Deduct 408 from 430 and we're left 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.

On to step 9:
51 can be fit into 220 4 times, resulting in a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 5301.784
If we subtract 204 from 220, we get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 10:
160 divided by 51 is 3 with a remainder of 7.
The next digit of our result is 3. 
Result so far: 5301.7843
Subtract 153 from 160 to get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Step 11:
70 divided by 51 is 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 5301.78431
If we subtract 51 from 70, we get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 12:
If we divide 190 by 51, we get 3 and a remainder of 37.
Put 3 as the next digit of the answer. 
Result so far: 5301.784313
Deduct 153 from 190 and we're left 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.

On to step 13:
370 divided by 51 is 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 5301.7843137
If we subtract 357 from 370, we get 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 14:
130 divided by 51 is 2 with a remainder of 28.
Use 2 as the next digit of our solution. 
Result so far: 5301.78431372
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.

After the division, we end up with 5301.78431372 and a remainder of 2.8e-08.
