Let's divide 668798 by 77
Let's see how many times 77 fits into 668798.

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
Subtracting 0 from 6 leaves us with 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 77

Going ahead to step 2:
If we divide 66 by 77, we get 0 and a remainder of 66.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 66 and we're left with 66.
Take the next digit (8) from the dividend and append it to 66, then repeat: 668 / 77

Step 3:
668 divided by 77 is 8 with a remainder of 52.
The next digit of our result is 8. 
Result so far: 8.0
Deduct 616 from 668 and we're left with 52.
Bring next digit (7) of the dividend behind the 52 and repeat the process: 527 / 77

Let's proceed to step 4:
77 can be fit into 527 6 times, resulting in a remainder of 65.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
Subtracting 462 from 527 leaves us with 65.
Take the next digit (9) from the dividend and append it to 65, then repeat: 659 / 77

Let's proceed to step 5:
If we divide 659 by 77, we get 8 and a remainder of 43.
Put 8 as the next digit of the answer. 
Result so far: 868.0
If we take 616 away from 659, we end up with 43.
Take the next digit (8) from the dividend and append it to 43, then repeat: 438 / 77

Advancing to step 6:
77 goes into 438 5 times with a remainder of 53.
Put 5 as the next digit of the answer. 
Result so far: 8685.0
Deduct 385 from 438 and we're left with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 7:
77 can be fit into 530 6 times, resulting in a remainder of 68.
Record the quotient 6 as the next digit in the result. 
Result so far: 8685.6
If we take 462 away from 530, we end up with 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

On to step 8:
If we divide 680 by 77, we get 8 and a remainder of 64.
Use 8 as the next digit of our solution. 
Result so far: 8685.68
Subtract 616 from 680 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

Let's proceed to step 9:
77 can be fit into 640 8 times, resulting in a remainder of 24.
The next digit of our result is 8. 
Result so far: 8685.688
Subtracting 616 from 640 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final result is 8685.688 with a remainder of 0.0024.
