668441 ÷ 77 
We want to divide 668441 by 77.

Advancing to step 1:
6 divided by 77 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 77

Going ahead to step 2:
When dividing 66 by 77, we get 0 with a remainder of 66.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 66, we end up with 66.
Grab the next digit (8) from the dividend, add it to 66, then carry on: 668 / 77

Step 3:
77 goes into 668 8 times with a remainder of 52.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 616 from 668, we get 52.
Bring next digit (4) of the dividend behind the 52 and repeat the process: 524 / 77

Advancing to step 4:
If we divide 524 by 77, we get 6 and a remainder of 62.
The number 6 becomes the next digit in our result. 
Result so far: 86.0
Deduct 462 from 524 and we're left with 62.
Include the next digit (4) from the dividend after 62, then repeat: 624 / 77

Moving on to step 5:
77 can be fit into 624 8 times, resulting in a remainder of 8.
Use 8 as the next digit of our solution. 
Result so far: 868.0
The remainder is 8 after subtracting 616 from 624.
Fetch the next digit (1) from the dividend, attach it to 8 and continue: 81 / 77

On to step 6:
77 goes into 81 1 times with a remainder of 4.
The number 1 becomes the next digit in our result. 
Result so far: 8681.0
Subtract 77 from 81 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
The number 77 fits into 40 0 times, leaving a remainder of 40.
The next digit of our result is 0. 
Result so far: 8681.0
Deduct 0 from 40 and we're left with 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 8:
The number 77 fits into 400 5 times, leaving a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 8681.05
Subtracting 385 from 400 leaves us with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 9:
When dividing 150 by 77, we get 1 with a remainder of 73.
Record the quotient 1 as the next digit in the result. 
Result so far: 8681.051
Deduct 77 from 150 and we're left with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 10:
730 divided by 77 is 9 with a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 8681.0519
Deduct 693 from 730 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 11:
370 divided by 77 is 4 with a remainder of 62.
Use 4 as the next digit of our solution. 
Result so far: 8681.05194
Deduct 308 from 370 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 12:
When dividing 620 by 77, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 8681.051948
Deduct 616 from 620 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Step 13:
77 goes into 40 0 times with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 8681.051948
Subtract 0 from 40 to get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 14:
The number 77 fits into 400 5 times, leaving a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 8681.05194805
If we take 385 away from 400, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 8681.05194805 with a remainder of 1.5e-08.
