We divide 687389 by 77
We're looking to find how many times 77 goes into 687389.

On to step 1:
The number 77 fits into 6 0 times, leaving a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 77

Moving on to step 2:
77 can be fit into 68 0 times, resulting in a remainder of 68.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 68, we end up with 68.
Take the next digit (7) from the dividend and append it to 68, then repeat: 687 / 77

Going ahead to step 3:
When dividing 687 by 77, we get 8 with a remainder of 71.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Deduct 616 from 687 and we're left with 71.
Grab the next digit (3) from the dividend, add it to 71, then carry on: 713 / 77

On to step 4:
If we divide 713 by 77, we get 9 and a remainder of 20.
Use 9 as the next digit of our solution. 
Result so far: 89.0
The remainder is 20 after subtracting 693 from 713.
Append the next digit (8) from the dividend to 20 and continue with: 208 / 77

On to step 5:
208 divided by 77 is 2 with a remainder of 54.
The number 2 becomes the next digit in our result. 
Result so far: 892.0
The remainder is 54 after subtracting 154 from 208.
Append the next digit (9) from the dividend to 54 and continue with: 549 / 77

Step 6:
When dividing 549 by 77, we get 7 with a remainder of 10.
Put 7 as the next digit of the answer. 
Result so far: 8927.0
Subtracting 539 from 549 leaves us with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Let's proceed to step 7:
77 can be fit into 100 1 times, resulting in a remainder of 23.
Use 1 as the next digit of our solution. 
Result so far: 8927.1
If we take 77 away from 100, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Moving on to step 8:
77 goes into 230 2 times with a remainder of 76.
The next digit of our result is 2. 
Result so far: 8927.12
The remainder is 76 after subtracting 154 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

Advancing to step 9:
The number 77 fits into 760 9 times, leaving a remainder of 67.
Use 9 as the next digit of our solution. 
Result so far: 8927.129
The remainder is 67 after subtracting 693 from 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 670, and continue the process.

Moving on to step 10:
670 divided by 77 is 8 with a remainder of 54.
Put 8 as the next digit of the answer. 
Result so far: 8927.1298
If we subtract 616 from 670, we get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 11:
540 divided by 77 is 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 8927.12987
The remainder is 1 after subtracting 539 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 12:
If we divide 10 by 77, we get 0 and a remainder of 10.
Write down 0 as next digit of the result. 
Result so far: 8927.12987
If we take 0 away from 10, we end up with 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 13:
When dividing 100 by 77, we get 1 with a remainder of 23.
The number 1 becomes the next digit in our result. 
Result so far: 8927.1298701
If we take 77 away from 100, we end up with 23.
Since there are no more digits in the dividend, we add a zero to the remainder making it 230, and continue the process.

Going ahead to step 14:
77 can be fit into 230 2 times, resulting in a remainder of 76.
The number 2 becomes the next digit in our result. 
Result so far: 8927.12987012
The remainder is 76 after subtracting 154 from 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 760, and continue the process.

The final result is 8927.12987012 with a remainder of 7.6e-08.
