We're dividing 30742271 by 519 
We want to divide 30742271 by 519.

Step 1:
The number 519 fits into 3 0 times, leaving a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 519

Going ahead to step 2:
If we divide 30 by 519, we get 0 and a remainder of 30.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 30 after subtracting 0 from 30.
Fetch the next digit (7) from the dividend, attach it to 30 and continue: 307 / 519

On to step 3:
The number 519 fits into 307 0 times, leaving a remainder of 307.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 307, we get 307.
Fetch the next digit (4) from the dividend, attach it to 307 and continue: 3074 / 519

Moving on to step 4:
3074 divided by 519 is 5 with a remainder of 479.
Put 5 as the next digit of the answer. 
Result so far: 5.0
Subtracting 2595 from 3074 leaves us with 479.
Append the next digit (2) from the dividend to 479 and continue with: 4792 / 519

Advancing to step 5:
The number 519 fits into 4792 9 times, leaving a remainder of 121.
Write down 9 as next digit of the result. 
Result so far: 59.0
Deduct 4671 from 4792 and we're left with 121.
Append the next digit (2) from the dividend to 121 and continue with: 1212 / 519

Moving on to step 6:
When dividing 1212 by 519, we get 2 with a remainder of 174.
Use 2 as the next digit of our solution. 
Result so far: 592.0
If we take 1038 away from 1212, we end up with 174.
Fetch the next digit (7) from the dividend, attach it to 174 and continue: 1747 / 519

Advancing to step 7:
519 can be fit into 1747 3 times, resulting in a remainder of 190.
Put 3 as the next digit of the answer. 
Result so far: 5923.0
Deduct 1557 from 1747 and we're left with 190.
Grab the next digit (1) from the dividend, add it to 190, then carry on: 1901 / 519

Advancing to step 8:
519 goes into 1901 3 times with a remainder of 344.
Record the quotient 3 as the next digit in the result. 
Result so far: 59233.0
If we subtract 1557 from 1901, we get 344.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3440, and continue the process.

Step 9:
If we divide 3440 by 519, we get 6 and a remainder of 326.
Write down 6 as next digit of the result. 
Result so far: 59233.6
Deduct 3114 from 3440 and we're left with 326.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3260, and continue the process.

On to step 10:
If we divide 3260 by 519, we get 6 and a remainder of 146.
The next digit of our result is 6. 
Result so far: 59233.66
If we take 3114 away from 3260, we end up with 146.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1460, and continue the process.

After the division, we end up with 59233.66 and a remainder of 0.146.
