We look at the division of 573863 by 66 
We want to divide 573863 by 66.

On to step 1:
The number 66 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 66

Going ahead to step 2:
66 goes into 57 0 times with a remainder of 57.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 57 after subtracting 0 from 57.
Bring next digit (3) of the dividend behind the 57 and repeat the process: 573 / 66

Going ahead to step 3:
If we divide 573 by 66, we get 8 and a remainder of 45.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
If we subtract 528 from 573, we get 45.
Include the next digit (8) from the dividend after 45, then repeat: 458 / 66

Let's proceed to step 4:
If we divide 458 by 66, we get 6 and a remainder of 62.
Put 6 as the next digit of the answer. 
Result so far: 86.0
If we subtract 396 from 458, we get 62.
Include the next digit (6) from the dividend after 62, then repeat: 626 / 66

Let's proceed to step 5:
The number 66 fits into 626 9 times, leaving a remainder of 32.
Put 9 as the next digit of the answer. 
Result so far: 869.0
Deduct 594 from 626 and we're left with 32.
Include the next digit (3) from the dividend after 32, then repeat: 323 / 66

On to step 6:
If we divide 323 by 66, we get 4 and a remainder of 59.
Write down 4 as next digit of the result. 
Result so far: 8694.0
The remainder is 59 after subtracting 264 from 323.
Since there are no more digits in the dividend, we add a zero to the remainder making it 590, and continue the process.

Going ahead to step 7:
When dividing 590 by 66, we get 8 with a remainder of 62.
Put 8 as the next digit of the answer. 
Result so far: 8694.8
The remainder is 62 after subtracting 528 from 590.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 8:
When dividing 620 by 66, we get 9 with a remainder of 26.
The next digit of our result is 9. 
Result so far: 8694.89
Deduct 594 from 620 and we're left with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 9:
The number 66 fits into 260 3 times, leaving a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 8694.893
If we take 198 away from 260, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 10:
When dividing 620 by 66, we get 9 with a remainder of 26.
The next digit of our result is 9. 
Result so far: 8694.8939
If we subtract 594 from 620, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Advancing to step 11:
66 can be fit into 260 3 times, resulting in a remainder of 62.
Put 3 as the next digit of the answer. 
Result so far: 8694.89393
If we take 198 away from 260, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 12:
If we divide 620 by 66, we get 9 and a remainder of 26.
The next digit of our result is 9. 
Result so far: 8694.893939
Subtracting 594 from 620 leaves us with 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Moving on to step 13:
66 can be fit into 260 3 times, resulting in a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 8694.8939393
Subtracting 198 from 260 leaves us with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 14:
When dividing 620 by 66, we get 9 with a remainder of 26.
The number 9 becomes the next digit in our result. 
Result so far: 8694.89393939
If we subtract 594 from 620, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The quotient of the division is 8694.89393939, and the remainder is 2.6e-08.
