We divide 666577 by 77
Let's see how many times 77 fits into 666577.

Moving on to step 1:
If we divide 6 by 77, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 77

Going ahead to step 2:
77 can be fit into 66 0 times, resulting in a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Append the next digit (6) from the dividend to 66 and continue with: 666 / 77

Advancing to step 3:
When dividing 666 by 77, we get 8 with a remainder of 50.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
If we subtract 616 from 666, we get 50.
Take the next digit (5) from the dividend and append it to 50, then repeat: 505 / 77

Step 4:
The number 77 fits into 505 6 times, leaving a remainder of 43.
The next digit of our result is 6. 
Result so far: 86.0
Subtract 462 from 505 to get 43.
Include the next digit (7) from the dividend after 43, then repeat: 437 / 77

Advancing to step 5:
When dividing 437 by 77, we get 5 with a remainder of 52.
The number 5 becomes the next digit in our result. 
Result so far: 865.0
The remainder is 52 after subtracting 385 from 437.
Include the next digit (7) from the dividend after 52, then repeat: 527 / 77

Step 6:
77 goes into 527 6 times with a remainder of 65.
The number 6 becomes the next digit in our result. 
Result so far: 8656.0
If we subtract 462 from 527, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Advancing to step 7:
650 divided by 77 is 8 with a remainder of 34.
Write down 8 as next digit of the result. 
Result so far: 8656.8
Subtract 616 from 650 to 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 8:
340 divided by 77 is 4 with a remainder of 32.
Write down 4 as next digit of the result. 
Result so far: 8656.84
If we take 308 away from 340, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 9:
When dividing 320 by 77, we get 4 with a remainder of 12.
Record the quotient 4 as the next digit in the result. 
Result so far: 8656.844
If we take 308 away from 320, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 8656.844 with a remaining 0.0012.
