We look at the division of 81246530 by 516 
We're looking to find how many times 516 goes into 81246530.

Let's proceed to step 1:
If we divide 8 by 516, we get 0 and a remainder of 8.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Include the next digit (1) from the dividend after 8, then repeat: 81 / 516

Moving on to step 2:
516 can be fit into 81 0 times, resulting in a remainder of 81.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 81, we get 81.
Bring next digit (2) of the dividend behind the 81 and repeat the process: 812 / 516

Advancing to step 3:
812 divided by 516 is 1 with a remainder of 296.
The next digit of our result is 1. 
Result so far: 1.0
Deduct 516 from 812 and we're left with 296.
Fetch the next digit (4) from the dividend, attach it to 296 and continue: 2964 / 516

Going ahead to step 4:
When dividing 2964 by 516, we get 5 with a remainder of 384.
Use 5 as the next digit of our solution. 
Result so far: 15.0
Subtract 2580 from 2964 to get 384.
Grab the next digit (6) from the dividend, add it to 384, then carry on: 3846 / 516

Going ahead to step 5:
The number 516 fits into 3846 7 times, leaving a remainder of 234.
The number 7 becomes the next digit in our result. 
Result so far: 157.0
If we subtract 3612 from 3846, we get 234.
Append the next digit (5) from the dividend to 234 and continue with: 2345 / 516

On to step 6:
516 goes into 2345 4 times with a remainder of 281.
The next digit of our result is 4. 
Result so far: 1574.0
Subtract 2064 from 2345 to get 281.
Take the next digit (3) from the dividend and append it to 281, then repeat: 2813 / 516

Advancing to step 7:
The number 516 fits into 2813 5 times, leaving a remainder of 233.
Write down 5 as next digit of the result. 
Result so far: 15745.0
If we subtract 2580 from 2813, we get 233.
Fetch the next digit (0) from the dividend, attach it to 233 and continue: 2330 / 516

Step 8:
2330 divided by 516 is 4 with a remainder of 266.
Put 4 as the next digit of the answer. 
Result so far: 157454.0
Subtracting 2064 from 2330 leaves us with 266.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2660, and continue the process.

Going ahead to step 9:
The number 516 fits into 2660 5 times, leaving a remainder of 80.
The number 5 becomes the next digit in our result. 
Result so far: 157454.5
If we take 2580 away from 2660, we end up with 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 800, and continue the process.

Let's proceed to step 10:
If we divide 800 by 516, we get 1 and a remainder of 284.
The number 1 becomes the next digit in our result. 
Result so far: 157454.51
Subtract 516 from 800 to get 284.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2840, and continue the process.

Let's proceed to step 11:
When dividing 2840 by 516, we get 5 with a remainder of 260.
The number 5 becomes the next digit in our result. 
Result so far: 157454.515
If we take 2580 away from 2840, we end up with 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2600, and continue the process.

Moving on to step 12:
516 can be fit into 2600 5 times, resulting in a remainder of 20.
Put 5 as the next digit of the answer. 
Result so far: 157454.5155
Subtract 2580 from 2600 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

After the division, we end up with 157454.5155 and a remainder of 0.0002.
