We're dividing 30211805 by 516 
We're looking to find how many times 516 goes into 30211805.

Going ahead to step 1:
If we divide 3 by 516, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (0) from the dividend, add it to 3, then carry on: 30 / 516

Moving on to step 2:
516 goes into 30 0 times with a remainder of 30.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 30, we end up with 30.
Grab the next digit (2) from the dividend, add it to 30, then carry on: 302 / 516

Step 3:
302 divided by 516 is 0 with a remainder of 302.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 302 leaves us with 302.
Take the next digit (1) from the dividend and append it to 302, then repeat: 3021 / 516

On to step 4:
If we divide 3021 by 516, we get 5 and a remainder of 441.
The next digit of our result is 5. 
Result so far: 5.0
Subtracting 2580 from 3021 leaves us with 441.
Grab the next digit (1) from the dividend, add it to 441, then carry on: 4411 / 516

Moving on to step 5:
When dividing 4411 by 516, we get 8 with a remainder of 283.
Write down 8 as next digit of the result. 
Result so far: 58.0
Subtracting 4128 from 4411 leaves us with 283.
Grab the next digit (8) from the dividend, add it to 283, then carry on: 2838 / 516

Moving on to step 6:
The number 516 fits into 2838 5 times, leaving a remainder of 258.
Put 5 as the next digit of the answer. 
Result so far: 585.0
Subtracting 2580 from 2838 leaves us with 258.
Fetch the next digit (0) from the dividend, attach it to 258 and continue: 2580 / 516

On to step 7:
516 can be fit into 2580 5 times, resulting in a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 5855.0
Deduct 2580 from 2580 and we're left with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 516

Step 8:
If we divide 5 by 516, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 58550.0
The remainder is 5 after subtracting 0 from 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Going ahead to step 9:
The number 516 fits into 50 0 times, leaving a remainder of 50.
The next digit of our result is 0. 
Result so far: 58550.0
Deduct 0 from 50 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 10:
516 can be fit into 500 0 times, resulting in a remainder of 500.
Put 0 as the next digit of the answer. 
Result so far: 58550.0
The remainder is 500 after subtracting 0 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5000, and continue the process.

Our division results in 58550.0 with a remaining 0.5.
