80853783 ÷ 516 
Our goal is to divide 80853783 by 516.

On to step 1:
8 divided by 516 is 0 with a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 8 to get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 516

Going ahead to step 2:
516 goes into 80 0 times with a remainder of 80.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 80, we get 80.
Include the next digit (8) from the dividend after 80, then repeat: 808 / 516

Going ahead to step 3:
The number 516 fits into 808 1 times, leaving a remainder of 292.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Deduct 516 from 808 and we're left with 292.
Bring next digit (5) of the dividend behind the 292 and repeat the process: 2925 / 516

Going ahead to step 4:
When dividing 2925 by 516, we get 5 with a remainder of 345.
Put 5 as the next digit of the answer. 
Result so far: 15.0
If we take 2580 away from 2925, we end up with 345.
Grab the next digit (3) from the dividend, add it to 345, then carry on: 3453 / 516

Step 5:
3453 divided by 516 is 6 with a remainder of 357.
Write down 6 as next digit of the result. 
Result so far: 156.0
If we subtract 3096 from 3453, we get 357.
Fetch the next digit (7) from the dividend, attach it to 357 and continue: 3577 / 516

Let's proceed to step 6:
516 can be fit into 3577 6 times, resulting in a remainder of 481.
The next digit of our result is 6. 
Result so far: 1566.0
The remainder is 481 after subtracting 3096 from 3577.
Fetch the next digit (8) from the dividend, attach it to 481 and continue: 4818 / 516

Step 7:
The number 516 fits into 4818 9 times, leaving a remainder of 174.
The next digit of our result is 9. 
Result so far: 15669.0
Subtract 4644 from 4818 to get 174.
Append the next digit (3) from the dividend to 174 and continue with: 1743 / 516

Advancing to step 8:
The number 516 fits into 1743 3 times, leaving a remainder of 195.
The number 3 becomes the next digit in our result. 
Result so far: 156693.0
If we subtract 1548 from 1743, we get 195.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1950, and continue the process.

On to step 9:
If we divide 1950 by 516, we get 3 and a remainder of 402.
Put 3 as the next digit of the answer. 
Result so far: 156693.3
If we take 1548 away from 1950, we end up with 402.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4020, and continue the process.

Advancing to step 10:
4020 divided by 516 is 7 with a remainder of 408.
The number 7 becomes the next digit in our result. 
Result so far: 156693.37
Subtracting 3612 from 4020 leaves us with 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 11:
4080 divided by 516 is 7 with a remainder of 468.
Record the quotient 7 as the next digit in the result. 
Result so far: 156693.377
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.

After the division, we end up with 156693.377 and a remainder of 0.0468.
