We divide 520813 by 66
We're looking to find how many times 66 goes into 520813.

Step 1:
The number 66 fits into 5 0 times, leaving a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 5 after subtracting 0 from 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 66

Let's proceed to step 2:
66 can be fit into 52 0 times, resulting in a remainder of 52.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 52 leaves us with 52.
Include the next digit (0) from the dividend after 52, then repeat: 520 / 66

Going ahead to step 3:
If we divide 520 by 66, we get 7 and a remainder of 58.
The next digit of our result is 7. 
Result so far: 7.0
Subtracting 462 from 520 leaves us with 58.
Grab the next digit (8) from the dividend, add it to 58, then carry on: 588 / 66

Going ahead to step 4:
588 divided by 66 is 8 with a remainder of 60.
Use 8 as the next digit of our solution. 
Result so far: 78.0
If we take 528 away from 588, we end up with 60.
Take the next digit (1) from the dividend and append it to 60, then repeat: 601 / 66

Moving on to step 5:
When dividing 601 by 66, we get 9 with a remainder of 7.
Use 9 as the next digit of our solution. 
Result so far: 789.0
If we subtract 594 from 601, we get 7.
Fetch the next digit (3) from the dividend, attach it to 7 and continue: 73 / 66

Advancing to step 6:
When dividing 73 by 66, we get 1 with a remainder of 7.
The next digit of our result is 1. 
Result so far: 7891.0
Subtracting 66 from 73 leaves us with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Going ahead to step 7:
If we divide 70 by 66, we get 1 and a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 7891.1
If we take 66 away from 70, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 8:
When dividing 40 by 66, we get 0 with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 7891.1
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

On to step 9:
When dividing 400 by 66, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 7891.106
The remainder is 4 after subtracting 396 from 400.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 10:
40 divided by 66 is 0 with a remainder of 40.
Record the quotient 0 as the next digit in the result. 
Result so far: 7891.106
The remainder is 40 after subtracting 0 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 11:
If we divide 400 by 66, we get 6 and a remainder of 4.
Write down 6 as next digit of the result. 
Result so far: 7891.10606
Subtracting 396 from 400 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

On to step 12:
The number 66 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 7891.10606
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Moving on to step 13:
If we divide 400 by 66, we get 6 and a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 7891.1060606
Deduct 396 from 400 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 14:
66 can be fit into 40 0 times, resulting in a remainder of 40.
The next digit of our result is 0. 
Result so far: 7891.1060606
If we take 0 away from 40, we end up with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Our division results in 7891.1060606 with a remaining 4e-08.
