Let's divide 688873 by 77
We want to divide 688873 by 77.

Step 1:
77 can be fit into 6 0 times, resulting in a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 77

On to step 2:
77 can be fit into 68 0 times, resulting in a remainder of 68.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 68, we get 68.
Fetch the next digit (8) from the dividend, attach it to 68 and continue: 688 / 77

Advancing to step 3:
77 goes into 688 8 times with a remainder of 72.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtracting 616 from 688 leaves us with 72.
Bring next digit (8) of the dividend behind the 72 and repeat the process: 728 / 77

Advancing to step 4:
The number 77 fits into 728 9 times, leaving a remainder of 35.
Use 9 as the next digit of our solution. 
Result so far: 89.0
If we take 693 away from 728, we end up with 35.
Bring next digit (7) of the dividend behind the 35 and repeat the process: 357 / 77

Advancing to step 5:
357 divided by 77 is 4 with a remainder of 49.
Use 4 as the next digit of our solution. 
Result so far: 894.0
If we subtract 308 from 357, we get 49.
Take the next digit (3) from the dividend and append it to 49, then repeat: 493 / 77

Let's proceed to step 6:
77 goes into 493 6 times with a remainder of 31.
Use 6 as the next digit of our solution. 
Result so far: 8946.0
Subtracting 462 from 493 leaves us with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Advancing to step 7:
When dividing 310 by 77, we get 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 8946.4
If we subtract 308 from 310, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
20 divided by 77 is 0 with a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 8946.4
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Moving on to step 9:
77 goes into 200 2 times with a remainder of 46.
The number 2 becomes the next digit in our result. 
Result so far: 8946.402
Deduct 154 from 200 and we're left with 46.
Since there are no more digits in the dividend, we add a zero to the remainder making it 460, and continue the process.

Going ahead to step 10:
77 goes into 460 5 times with a remainder of 75.
Put 5 as the next digit of the answer. 
Result so far: 8946.4025
Subtracting 385 from 460 leaves us with 75.
Since there are no more digits in the dividend, we add a zero to the remainder making it 750, and continue the process.

Going ahead to step 11:
77 goes into 750 9 times with a remainder of 57.
The number 9 becomes the next digit in our result. 
Result so far: 8946.40259
Deduct 693 from 750 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

On to step 12:
77 goes into 570 7 times with a remainder of 31.
The number 7 becomes the next digit in our result. 
Result so far: 8946.402597
Deduct 539 from 570 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

Let's proceed to step 13:
77 goes into 310 4 times with a remainder of 2.
The next digit of our result is 4. 
Result so far: 8946.4025974
Deduct 308 from 310 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 14:
77 can be fit into 20 0 times, resulting in a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 8946.4025974
If we subtract 0 from 20, we get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final result is 8946.4025974 with a remainder of 2e-08.
