577439 ÷ 66 
We want to figure out the number of times 577439 can be divided by 66.

Let's proceed to step 1:
5 divided by 66 is 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 66

On to step 2:
If we divide 57 by 66, we get 0 and a remainder of 57.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 57, we end up with 57.
Take the next digit (7) from the dividend and append it to 57, then repeat: 577 / 66

Moving on to step 3:
577 divided by 66 is 8 with a remainder of 49.
The number 8 becomes the next digit in our result. 
Result so far: 8.0
Deduct 528 from 577 and we're left with 49.
Grab the next digit (4) from the dividend, add it to 49, then carry on: 494 / 66

Moving on to step 4:
The number 66 fits into 494 7 times, leaving a remainder of 32.
Write down 7 as next digit of the result. 
Result so far: 87.0
The remainder is 32 after subtracting 462 from 494.
Grab the next digit (3) from the dividend, add it to 32, then carry on: 323 / 66

Let's proceed to step 5:
66 goes into 323 4 times with a remainder of 59.
Use 4 as the next digit of our solution. 
Result so far: 874.0
Subtracting 264 from 323 leaves us with 59.
Fetch the next digit (9) from the dividend, attach it to 59 and continue: 599 / 66

Let's proceed to step 6:
599 divided by 66 is 9 with a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 8749.0
Subtracting 594 from 599 leaves us with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 7:
66 goes into 50 0 times with a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 8749.0
The remainder is 50 after subtracting 0 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Let's proceed to step 8:
The number 66 fits into 500 7 times, leaving a remainder of 38.
Write down 7 as next digit of the result. 
Result so far: 8749.07
If we take 462 away from 500, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 9:
66 can be fit into 380 5 times, resulting in a remainder of 50.
Use 5 as the next digit of our solution. 
Result so far: 8749.075
Subtract 330 from 380 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Step 10:
The number 66 fits into 500 7 times, leaving a remainder of 38.
The number 7 becomes the next digit in our result. 
Result so far: 8749.0757
The remainder is 38 after subtracting 462 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Let's proceed to step 11:
66 goes into 380 5 times with a remainder of 50.
Put 5 as the next digit of the answer. 
Result so far: 8749.07575
If we subtract 330 from 380, we get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
If we divide 500 by 66, we get 7 and a remainder of 38.
Record the quotient 7 as the next digit in the result. 
Result so far: 8749.075757
The remainder is 38 after subtracting 462 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 13:
The number 66 fits into 380 5 times, leaving a remainder of 50.
The next digit of our result is 5. 
Result so far: 8749.0757575
Deduct 330 from 380 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 14:
If we divide 500 by 66, we get 7 and a remainder of 38.
Put 7 as the next digit of the answer. 
Result so far: 8749.07575757
If we take 462 away from 500, we end up with 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

The quotient of the division is 8749.07575757, and the remainder is 3.8e-08.
