660687 divided by 77 
Our goal is to divide 660687 by 77.

Advancing to step 1:
If we divide 6 by 77, we get 0 and a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 6 to get 6.
Grab the next digit (6) from the dividend, add it to 6, then carry on: 66 / 77

Going ahead to step 2:
If we divide 66 by 77, we get 0 and a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 66 to get 66.
Append the next digit (0) from the dividend to 66 and continue with: 660 / 77

Going ahead to step 3:
When dividing 660 by 77, we get 8 with a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 616 from 660 and we're left with 44.
Bring next digit (6) of the dividend behind the 44 and repeat the process: 446 / 77

Moving on to step 4:
446 divided by 77 is 5 with a remainder of 61.
Record the quotient 5 as the next digit in the result. 
Result so far: 85.0
The remainder is 61 after subtracting 385 from 446.
Bring next digit (8) of the dividend behind the 61 and repeat the process: 618 / 77

Moving on to step 5:
618 divided by 77 is 8 with a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 858.0
If we take 616 away from 618, we end up with 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 77

On to step 6:
77 can be fit into 27 0 times, resulting in a remainder of 27.
Put 0 as the next digit of the answer. 
Result so far: 8580.0
Subtract 0 from 27 to get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

On to step 7:
When dividing 270 by 77, we get 3 with a remainder of 39.
The number 3 becomes the next digit in our result. 
Result so far: 8580.3
If we subtract 231 from 270, we get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Advancing to step 8:
If we divide 390 by 77, we get 5 and a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 8580.35
If we take 385 away from 390, we end up 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.

Step 9:
77 can be fit into 50 0 times, resulting in a remainder of 50.
Record the quotient 0 as the next digit in the result. 
Result so far: 8580.35
If we subtract 0 from 50, 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 10:
500 divided by 77 is 6 with a remainder of 38.
The next digit of our result is 6. 
Result so far: 8580.3506
Subtracting 462 from 500 leaves us 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.

Moving on to step 11:
When dividing 380 by 77, we get 4 with a remainder of 72.
The next digit of our result is 4. 
Result so far: 8580.35064
If we subtract 308 from 380, we get 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

Advancing to step 12:
720 divided by 77 is 9 with a remainder of 27.
The next digit of our result is 9. 
Result so far: 8580.350649
If we subtract 693 from 720, we get 27.
Since there are no more digits in the dividend, we add a zero to the remainder making it 270, and continue the process.

Let's proceed to step 13:
77 goes into 270 3 times with a remainder of 39.
Record the quotient 3 as the next digit in the result. 
Result so far: 8580.3506493
The remainder is 39 after subtracting 231 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 14:
When dividing 390 by 77, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 8580.35064935
The remainder is 5 after subtracting 385 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The final outcome is 8580.35064935, with a leftover of 5e-09.
