65152909 ÷ 519 
We want to figure out the number of times 65152909 can be divided by 519.

Step 1:
If we divide 6 by 519, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Take the next digit (5) from the dividend and append it to 6, then repeat: 65 / 519

Advancing to step 2:
519 goes into 65 0 times with a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 65 to get 65.
Bring next digit (1) of the dividend behind the 65 and repeat the process: 651 / 519

Let's proceed to step 3:
When dividing 651 by 519, we get 1 with a remainder of 132.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 519 from 651, we get 132.
Fetch the next digit (5) from the dividend, attach it to 132 and continue: 1325 / 519

Advancing to step 4:
When dividing 1325 by 519, we get 2 with a remainder of 287.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 287 after subtracting 1038 from 1325.
Bring next digit (2) of the dividend behind the 287 and repeat the process: 2872 / 519

Advancing to step 5:
The number 519 fits into 2872 5 times, leaving a remainder of 277.
Use 5 as the next digit of our solution. 
Result so far: 125.0
The remainder is 277 after subtracting 2595 from 2872.
Include the next digit (9) from the dividend after 277, then repeat: 2779 / 519

Going ahead to step 6:
If we divide 2779 by 519, we get 5 and a remainder of 184.
The number 5 becomes the next digit in our result. 
Result so far: 1255.0
Deduct 2595 from 2779 and we're left with 184.
Fetch the next digit (0) from the dividend, attach it to 184 and continue: 1840 / 519

Step 7:
If we divide 1840 by 519, we get 3 and a remainder of 283.
The next digit of our result is 3. 
Result so far: 12553.0
Deduct 1557 from 1840 and we're left with 283.
Take the next digit (9) from the dividend and append it to 283, then repeat: 2839 / 519

Step 8:
2839 divided by 519 is 5 with a remainder of 244.
Put 5 as the next digit of the answer. 
Result so far: 125535.0
Subtract 2595 from 2839 to get 244.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2440, and continue the process.

Moving on to step 9:
When dividing 2440 by 519, we get 4 with a remainder of 364.
The number 4 becomes the next digit in our result. 
Result so far: 125535.4
The remainder is 364 after subtracting 2076 from 2440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3640, and continue the process.

Moving on to step 10:
519 goes into 3640 7 times with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 125535.47
The remainder is 7 after subtracting 3633 from 3640.
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:
When dividing 70 by 519, we get 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 125535.47
Subtract 0 from 70 to get 70.
Since there are no more digits in the dividend, we add a zero to the remainder making it 700, and continue the process.

Step 12:
519 goes into 700 1 times with a remainder of 181.
Use 1 as the next digit of our solution. 
Result so far: 125535.4701
Subtracting 519 from 700 leaves us with 181.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1810, and continue the process.

Going ahead to step 13:
The number 519 fits into 1810 3 times, leaving a remainder of 253.
The next digit of our result is 3. 
Result so far: 125535.47013
Subtract 1557 from 1810 to get 253.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Let's proceed to step 14:
When dividing 2530 by 519, we get 4 with a remainder of 454.
Record the quotient 4 as the next digit in the result. 
Result so far: 125535.470134
The remainder is 454 after subtracting 2076 from 2530.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4540, and continue the process.

On to step 15:
519 goes into 4540 8 times with a remainder of 388.
Put 8 as the next digit of the answer. 
Result so far: 125535.4701348
If we take 4152 away from 4540, we end up with 388.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3880, and continue the process.

On to step 16:
519 goes into 3880 7 times with a remainder of 247.
Put 7 as the next digit of the answer. 
Result so far: 125535.47013487
Subtracting 3633 from 3880 leaves us with 247.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2470, and continue the process.

In conclusion, the division gives 125535.47013487 with a balance of 2.47e-07.
