72391659 divided by 516 
We want to divide 72391659 by 516.

Step 1:
516 can be fit into 7 0 times, resulting in a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Bring next digit (2) of the dividend behind the 7 and repeat the process: 72 / 516

Moving on to step 2:
72 divided by 516 is 0 with a remainder of 72.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 72 to get 72.
Grab the next digit (3) from the dividend, add it to 72, then carry on: 723 / 516

On to step 3:
516 can be fit into 723 1 times, resulting in a remainder of 207.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 516 from 723 and we're left with 207.
Bring next digit (9) of the dividend behind the 207 and repeat the process: 2079 / 516

Let's proceed to step 4:
When dividing 2079 by 516, we get 4 with a remainder of 15.
The next digit of our result is 4. 
Result so far: 14.0
Subtract 2064 from 2079 to get 15.
Bring next digit (1) of the dividend behind the 15 and repeat the process: 151 / 516

Moving on to step 5:
516 can be fit into 151 0 times, resulting in a remainder of 151.
The next digit of our result is 0. 
Result so far: 140.0
If we subtract 0 from 151, we get 151.
Include the next digit (6) from the dividend after 151, then repeat: 1516 / 516

Advancing to step 6:
If we divide 1516 by 516, we get 2 and a remainder of 484.
Use 2 as the next digit of our solution. 
Result so far: 1402.0
If we subtract 1032 from 1516, we get 484.
Append the next digit (5) from the dividend to 484 and continue with: 4845 / 516

Moving on to step 7:
When dividing 4845 by 516, we get 9 with a remainder of 201.
Record the quotient 9 as the next digit in the result. 
Result so far: 14029.0
Subtract 4644 from 4845 to get 201.
Grab the next digit (9) from the dividend, add it to 201, then carry on: 2019 / 516

Moving on to step 8:
When dividing 2019 by 516, we get 3 with a remainder of 471.
Write down 3 as next digit of the result. 
Result so far: 140293.0
Subtract 1548 from 2019 to get 471.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4710, and continue the process.

Step 9:
4710 divided by 516 is 9 with a remainder of 66.
Use 9 as the next digit of our solution. 
Result so far: 140293.9
Subtracting 4644 from 4710 leaves us with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

Moving on to step 10:
The number 516 fits into 660 1 times, leaving a remainder of 144.
Record the quotient 1 as the next digit in the result. 
Result so far: 140293.91
The remainder is 144 after subtracting 516 from 660.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

On to step 11:
516 can be fit into 1440 2 times, resulting in a remainder of 408.
Record the quotient 2 as the next digit in the result. 
Result so far: 140293.912
If we subtract 1032 from 1440, we get 408.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4080, and continue the process.

Step 12:
When dividing 4080 by 516, we get 7 with a remainder of 468.
The next digit of our result is 7. 
Result so far: 140293.9127
The remainder is 468 after subtracting 3612 from 4080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

Let's proceed to step 13:
When dividing 4680 by 516, we get 9 with a remainder of 36.
Use 9 as the next digit of our solution. 
Result so far: 140293.91279
If we take 4644 away from 4680, we end up with 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 14:
If we divide 360 by 516, we get 0 and a remainder of 360.
The next digit of our result is 0. 
Result so far: 140293.91279
Subtract 0 from 360 to get 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

On to step 15:
516 goes into 3600 6 times with a remainder of 504.
Use 6 as the next digit of our solution. 
Result so far: 140293.9127906
The remainder is 504 after subtracting 3096 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5040, and continue the process.

Let's proceed to step 16:
If we divide 5040 by 516, we get 9 and a remainder of 396.
Record the quotient 9 as the next digit in the result. 
Result so far: 140293.91279069
Subtract 4644 from 5040 to get 396.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3960, and continue the process.

The final result is 140293.91279069 with a remainder of 3.96e-07.
