We look at the division of 539568 by 66 
We want to figure out the number of times 539568 can be divided by 66.

On to step 1:
The number 66 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 66

On to step 2:
66 goes into 53 0 times with a remainder of 53.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 53, we end up with 53.
Take the next digit (9) from the dividend and append it to 53, then repeat: 539 / 66

Advancing to step 3:
66 can be fit into 539 8 times, resulting in a remainder of 11.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 528 from 539, we get 11.
Fetch the next digit (5) from the dividend, attach it to 11 and continue: 115 / 66

Let's proceed to step 4:
66 can be fit into 115 1 times, resulting in a remainder of 49.
The next digit of our result is 1. 
Result so far: 81.0
Subtracting 66 from 115 leaves us with 49.
Fetch the next digit (6) from the dividend, attach it to 49 and continue: 496 / 66

Let's proceed to step 5:
496 divided by 66 is 7 with a remainder of 34.
Record the quotient 7 as the next digit in the result. 
Result so far: 817.0
Subtracting 462 from 496 leaves us with 34.
Grab the next digit (8) from the dividend, add it to 34, then carry on: 348 / 66

Let's proceed to step 6:
66 goes into 348 5 times with a remainder of 18.
Write down 5 as next digit of the result. 
Result so far: 8175.0
Subtract 330 from 348 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
66 can be fit into 180 2 times, resulting in a remainder of 48.
Put 2 as the next digit of the answer. 
Result so far: 8175.2
If we take 132 away from 180, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 8:
If we divide 480 by 66, we get 7 and a remainder of 18.
Write down 7 as next digit of the result. 
Result so far: 8175.27
If we take 462 away from 480, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 9:
180 divided by 66 is 2 with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 8175.272
Deduct 132 from 180 and we're left with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Let's proceed to step 10:
When dividing 480 by 66, we get 7 with a remainder of 18.
The number 7 becomes the next digit in our result. 
Result so far: 8175.2727
Subtract 462 from 480 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 11:
66 goes into 180 2 times with a remainder of 48.
The next digit of our result is 2. 
Result so far: 8175.27272
If we take 132 away from 180, we end up with 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

Advancing to step 12:
66 goes into 480 7 times with a remainder of 18.
Put 7 as the next digit of the answer. 
Result so far: 8175.272727
Subtract 462 from 480 to get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 13:
When dividing 180 by 66, we get 2 with a remainder of 48.
Write down 2 as next digit of the result. 
Result so far: 8175.2727272
If we subtract 132 from 180, we get 48.
Since there are no more digits in the dividend, we add a zero to the remainder making it 480, and continue the process.

On to step 14:
When dividing 480 by 66, we get 7 with a remainder of 18.
Record the quotient 7 as the next digit in the result. 
Result so far: 8175.27272727
If we subtract 462 from 480, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Our division results in 8175.27272727 with a remaining 1.8e-08.
