578636 ÷ 66 
We want to figure out the number of times 578636 can be divided by 66.

Let's proceed to step 1:
If we divide 5 by 66, we get 0 and a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 66

Let's proceed to step 2:
When dividing 57 by 66, we get 0 with a remainder of 57.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 57 to get 57.
Grab the next digit (8) from the dividend, add it to 57, then carry on: 578 / 66

Moving on to step 3:
66 can be fit into 578 8 times, resulting in a remainder of 50.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 528 from 578 and we're left with 50.
Include the next digit (6) from the dividend after 50, then repeat: 506 / 66

Going ahead to step 4:
The number 66 fits into 506 7 times, leaving a remainder of 44.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
Deduct 462 from 506 and we're left with 44.
Bring next digit (3) of the dividend behind the 44 and repeat the process: 443 / 66

Moving on to step 5:
66 can be fit into 443 6 times, resulting in a remainder of 47.
Put 6 as the next digit of the answer. 
Result so far: 876.0
If we take 396 away from 443, we end up with 47.
Include the next digit (6) from the dividend after 47, then repeat: 476 / 66

Going ahead to step 6:
66 can be fit into 476 7 times, resulting in a remainder of 14.
Use 7 as the next digit of our solution. 
Result so far: 8767.0
Deduct 462 from 476 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Let's proceed to step 7:
The number 66 fits into 140 2 times, leaving a remainder of 8.
The next digit of our result is 2. 
Result so far: 8767.2
Subtract 132 from 140 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 8:
When dividing 80 by 66, we get 1 with a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 8767.21
Deduct 66 from 80 and we're left with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Advancing to step 9:
66 can be fit into 140 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 8767.212
Subtract 132 from 140 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 10:
When dividing 80 by 66, we get 1 with a remainder of 14.
The number 1 becomes the next digit in our result. 
Result so far: 8767.2121
If we take 66 away from 80, we end up with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 11:
66 can be fit into 140 2 times, resulting in a remainder of 8.
Record the quotient 2 as the next digit in the result. 
Result so far: 8767.21212
If we subtract 132 from 140, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 12:
66 can be fit into 80 1 times, resulting in a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 8767.212121
Subtracting 66 from 80 leaves us with 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 13:
If we divide 140 by 66, we get 2 and a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 8767.2121212
Deduct 132 from 140 and we're left with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 14:
The number 66 fits into 80 1 times, leaving a remainder of 14.
Record the quotient 1 as the next digit in the result. 
Result so far: 8767.21212121
The remainder is 14 after subtracting 66 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Our division results in 8767.21212121 with a remaining 1.4e-08.
