525163 divided by 66 
We want to figure out the number of times 525163 can be divided by 66.

Step 1:
When dividing 5 by 66, we get 0 with a remainder of 5.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 66

Let's proceed to step 2:
52 divided by 66 is 0 with a remainder of 52.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 52 to get 52.
Include the next digit (5) from the dividend after 52, then repeat: 525 / 66

Moving on to step 3:
525 divided by 66 is 7 with a remainder of 63.
Record the quotient 7 as the next digit in the result. 
Result so far: 7.0
Deduct 462 from 525 and we're left with 63.
Take the next digit (1) from the dividend and append it to 63, then repeat: 631 / 66

Step 4:
66 goes into 631 9 times with a remainder of 37.
Record the quotient 9 as the next digit in the result. 
Result so far: 79.0
The remainder is 37 after subtracting 594 from 631.
Include the next digit (6) from the dividend after 37, then repeat: 376 / 66

Moving on to step 5:
If we divide 376 by 66, we get 5 and a remainder of 46.
Use 5 as the next digit of our solution. 
Result so far: 795.0
Subtract 330 from 376 to get 46.
Bring next digit (3) of the dividend behind the 46 and repeat the process: 463 / 66

Let's proceed to step 6:
66 can be fit into 463 7 times, resulting in a remainder of 1.
The next digit of our result is 7. 
Result so far: 7957.0
If we subtract 462 from 463, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 7:
The number 66 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 7957.0
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Step 8:
66 goes into 100 1 times with a remainder of 34.
The number 1 becomes the next digit in our result. 
Result so far: 7957.01
Deduct 66 from 100 and we're left with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 9:
When dividing 340 by 66, we get 5 with a remainder of 10.
Put 5 as the next digit of the answer. 
Result so far: 7957.015
If we subtract 330 from 340, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

On to step 10:
66 can be fit into 100 1 times, resulting in a remainder of 34.
The next digit of our result is 1. 
Result so far: 7957.0151
If we subtract 66 from 100, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 11:
66 goes into 340 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 7957.01515
The remainder is 10 after subtracting 330 from 340.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 12:
66 can be fit into 100 1 times, resulting in a remainder of 34.
Put 1 as the next digit of the answer. 
Result so far: 7957.015151
The remainder is 34 after subtracting 66 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Moving on to step 13:
66 goes into 340 5 times with a remainder of 10.
Record the quotient 5 as the next digit in the result. 
Result so far: 7957.0151515
If we take 330 away from 340, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 14:
The number 66 fits into 100 1 times, leaving a remainder of 34.
Record the quotient 1 as the next digit in the result. 
Result so far: 7957.01515151
If we subtract 66 from 100, we get 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

Our division results in 7957.01515151 with a remaining 3.4e-08.
