We divide 519720 by 66
Let's see how many times 66 fits into 519720.

Step 1:
The number 66 fits into 5 0 times, leaving a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 5, we end up with 5.
Append the next digit (1) from the dividend to 5 and continue with: 51 / 66

On to step 2:
66 goes into 51 0 times with a remainder of 51.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 51, we end up with 51.
Grab the next digit (9) from the dividend, add it to 51, then carry on: 519 / 66

Advancing to step 3:
519 divided by 66 is 7 with a remainder of 57.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Deduct 462 from 519 and we're left with 57.
Grab the next digit (7) from the dividend, add it to 57, then carry on: 577 / 66

Going ahead to step 4:
The number 66 fits into 577 8 times, leaving a remainder of 49.
The next digit of our result is 8. 
Result so far: 78.0
Subtracting 528 from 577 leaves us with 49.
Fetch the next digit (2) from the dividend, attach it to 49 and continue: 492 / 66

Moving on to step 5:
66 can be fit into 492 7 times, resulting in a remainder of 30.
Write down 7 as next digit of the result. 
Result so far: 787.0
If we take 462 away from 492, we end up with 30.
Append the next digit (0) from the dividend to 30 and continue with: 300 / 66

Let's proceed to step 6:
If we divide 300 by 66, we get 4 and a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 7874.0
If we take 264 away from 300, 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.

Going ahead to step 7:
If we divide 360 by 66, we get 5 and a remainder of 30.
The number 5 becomes the next digit in our result. 
Result so far: 7874.5
If we take 330 away from 360, we end up with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 8:
66 goes into 300 4 times with a remainder of 36.
Record the quotient 4 as the next digit in the result. 
Result so far: 7874.54
Subtract 264 from 300 to get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Moving on to step 9:
66 goes into 360 5 times with a remainder of 30.
Use 5 as the next digit of our solution. 
Result so far: 7874.545
The remainder is 30 after subtracting 330 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Going ahead to step 10:
The number 66 fits into 300 4 times, leaving a remainder of 36.
Put 4 as the next digit of the answer. 
Result so far: 7874.5454
The remainder is 36 after subtracting 264 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Let's proceed to step 11:
66 can be fit into 360 5 times, resulting in a remainder of 30.
Record the quotient 5 as the next digit in the result. 
Result so far: 7874.54545
The remainder is 30 after subtracting 330 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 12:
66 goes into 300 4 times with a remainder of 36.
The next digit of our result is 4. 
Result so far: 7874.545454
The remainder is 36 after subtracting 264 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

On to step 13:
The number 66 fits into 360 5 times, leaving a remainder of 30.
Put 5 as the next digit of the answer. 
Result so far: 7874.5454545
Deduct 330 from 360 and we're left with 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 300, and continue the process.

Advancing to step 14:
When dividing 300 by 66, we get 4 with a remainder of 36.
The next digit of our result is 4. 
Result so far: 7874.54545454
The remainder is 36 after subtracting 264 from 300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

The final outcome is 7874.54545454, with a leftover of 3.6e-08.
