Let's divide 691728 by 77
We want to divide 691728 by 77.

Advancing to step 1:
When dividing 6 by 77, we get 0 with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 77

Step 2:
77 can be fit into 69 0 times, resulting in a remainder of 69.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 69, we end up with 69.
Bring next digit (1) of the dividend behind the 69 and repeat the process: 691 / 77

Step 3:
When dividing 691 by 77, we get 8 with a remainder of 75.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 616 from 691 and we're left with 75.
Include the next digit (7) from the dividend after 75, then repeat: 757 / 77

On to step 4:
If we divide 757 by 77, we get 9 and a remainder of 64.
The next digit of our result is 9. 
Result so far: 89.0
If we take 693 away from 757, we end up with 64.
Grab the next digit (2) from the dividend, add it to 64, then carry on: 642 / 77

Going ahead to step 5:
If we divide 642 by 77, we get 8 and a remainder of 26.
The next digit of our result is 8. 
Result so far: 898.0
If we take 616 away from 642, we end up with 26.
Bring next digit (8) of the dividend behind the 26 and repeat the process: 268 / 77

On to step 6:
77 can be fit into 268 3 times, resulting in a remainder of 37.
The number 3 becomes the next digit in our result. 
Result so far: 8983.0
If we subtract 231 from 268, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 7:
If we divide 370 by 77, we get 4 and a remainder of 62.
The next digit of our result is 4. 
Result so far: 8983.4
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.

Step 8:
620 divided by 77 is 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 8983.48
Subtract 616 from 620 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.

Moving on to step 9:
77 can be fit into 40 0 times, resulting in a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 8983.48
If we take 0 away from 40, we end up 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.

Going ahead to step 10:
77 goes into 400 5 times with a remainder of 15.
Put 5 as the next digit of the answer. 
Result so far: 8983.4805
If we subtract 385 from 400, we get 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Advancing to step 11:
When dividing 150 by 77, we get 1 with a remainder of 73.
The next digit of our result is 1. 
Result so far: 8983.48051
The remainder is 73 after subtracting 77 from 150.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 12:
77 can be fit into 730 9 times, resulting in a remainder of 37.
Write down 9 as next digit of the result. 
Result so far: 8983.480519
Subtracting 693 from 730 leaves us 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.

Moving on to step 13:
77 can be fit into 370 4 times, resulting in a remainder of 62.
The next digit of our result is 4. 
Result so far: 8983.4805194
If we take 308 away from 370, we end up 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.

Let's proceed to step 14:
77 goes into 620 8 times with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 8983.48051948
Subtracting 616 from 620 leaves us 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.

Our division results in 8983.48051948 with a remaining 4e-09.
