We look at the division of 518049 by 51 
We want to figure out the number of times 518049 can be divided by 51.

Going ahead to step 1:
When dividing 5 by 51, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 51

Moving on to step 2:
When dividing 51 by 51, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
The remainder is 0 after subtracting 51 from 51.
Grab the next digit (8) from the dividend, add it to 0, then carry on: 8 / 51

Step 3:
When dividing 8 by 51, we get 0 with a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
Subtract 0 from 8 to get 8.
Include the next digit (0) from the dividend after 8, then repeat: 80 / 51

Going ahead to step 4:
80 divided by 51 is 1 with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 101.0
The remainder is 29 after subtracting 51 from 80.
Grab the next digit (4) from the dividend, add it to 29, then carry on: 294 / 51

On to step 5:
When dividing 294 by 51, we get 5 with a remainder of 39.
Record the quotient 5 as the next digit in the result. 
Result so far: 1015.0
The remainder is 39 after subtracting 255 from 294.
Bring next digit (9) of the dividend behind the 39 and repeat the process: 399 / 51

On to step 6:
399 divided by 51 is 7 with a remainder of 42.
Write down 7 as next digit of the result. 
Result so far: 10157.0
The remainder is 42 after subtracting 357 from 399.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 7:
51 can be fit into 420 8 times, resulting in a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 10157.8
If we subtract 408 from 420, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

On to step 8:
51 goes into 120 2 times with a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 10157.82
Deduct 102 from 120 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
51 goes into 180 3 times with a remainder of 27.
The next digit of our result is 3. 
Result so far: 10157.823
If we take 153 away from 180, we end up with 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 10:
51 goes into 270 5 times with a remainder of 15.
The next digit of our result is 5. 
Result so far: 10157.8235
Subtracting 255 from 270 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 11:
If we divide 150 by 51, we get 2 and a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 10157.82352
If we take 102 away from 150, we end up 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.

Let's proceed to step 12:
51 can be fit into 480 9 times, resulting in a remainder of 21.
The next digit of our result is 9. 
Result so far: 10157.823529
The remainder is 21 after subtracting 459 from 480.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Step 13:
210 divided by 51 is 4 with a remainder of 6.
Record the quotient 4 as the next digit in the result. 
Result so far: 10157.8235294
Deduct 204 from 210 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 14:
If we divide 60 by 51, we get 1 and a remainder of 9.
Put 1 as the next digit of the answer. 
Result so far: 10157.82352941
Subtract 51 from 60 to get 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

The final result is 10157.82352941 with a remainder of 9e-09.
