We look at the division of 265086 by 51 
We want to figure out the number of times 265086 can be divided by 51.

Going ahead to step 1:
When dividing 2 by 51, we get 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 51

Let's proceed to step 2:
26 divided by 51 is 0 with a remainder of 26.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 26 and we're left with 26.
Include the next digit (5) from the dividend after 26, then repeat: 265 / 51

Step 3:
265 divided by 51 is 5 with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we take 255 away from 265, we end up with 10.
Bring next digit (0) of the dividend behind the 10 and repeat the process: 100 / 51

Let's proceed to step 4:
When dividing 100 by 51, we get 1 with a remainder of 49.
Use 1 as the next digit of our solution. 
Result so far: 51.0
Subtract 51 from 100 to get 49.
Include the next digit (8) from the dividend after 49, then repeat: 498 / 51

On to step 5:
498 divided by 51 is 9 with a remainder of 39.
The number 9 becomes the next digit in our result. 
Result so far: 519.0
If we take 459 away from 498, we end up with 39.
Grab the next digit (6) from the dividend, add it to 39, then carry on: 396 / 51

Let's proceed to step 6:
When dividing 396 by 51, we get 7 with a remainder of 39.
Put 7 as the next digit of the answer. 
Result so far: 5197.0
If we take 357 away from 396, we end up 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.

On to step 7:
390 divided by 51 is 7 with a remainder of 33.
The next digit of our result is 7. 
Result so far: 5197.7
Subtract 357 from 390 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Step 8:
51 goes into 330 6 times with a remainder of 24.
The number 6 becomes the next digit in our result. 
Result so far: 5197.76
Subtract 306 from 330 to get 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 9:
If we divide 240 by 51, we get 4 and a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 5197.764
If we subtract 204 from 240, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Going ahead to step 10:
When dividing 360 by 51, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 5197.7647
If we subtract 357 from 360, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 11:
30 divided by 51 is 0 with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 5197.7647
Deduct 0 from 30 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Let's proceed to step 12:
51 goes into 300 5 times with a remainder of 45.
Write down 5 as next digit of the result. 
Result so far: 5197.764705
If we take 255 away from 300, we end up with 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 13:
51 goes into 450 8 times with a remainder of 42.
Use 8 as the next digit of our solution. 
Result so far: 5197.7647058
If we subtract 408 from 450, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 14:
51 goes into 420 8 times with a remainder of 12.
Write down 8 as next digit of the result. 
Result so far: 5197.76470588
Subtracting 408 from 420 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The final result is 5197.76470588 with a remainder of 1.2e-08.
