We look at the division of 6748315 by 77 
We're looking to find how many times 77 goes into 6748315.

On to step 1:
6 divided by 77 is 0 with 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.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 77

Step 2:
67 divided by 77 is 0 with a remainder of 67.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 67 and we're left with 67.
Grab the next digit (4) from the dividend, add it to 67, then carry on: 674 / 77

On to step 3:
674 divided by 77 is 8 with a remainder of 58.
Write down 8 as next digit of the result. 
Result so far: 8.0
Subtract 616 from 674 to get 58.
Bring next digit (8) of the dividend behind the 58 and repeat the process: 588 / 77

Advancing to step 4:
77 can be fit into 588 7 times, resulting in a remainder of 49.
Put 7 as the next digit of the answer. 
Result so far: 87.0
If we subtract 539 from 588, we get 49.
Bring next digit (3) of the dividend behind the 49 and repeat the process: 493 / 77

Advancing to step 5:
If we divide 493 by 77, we get 6 and a remainder of 31.
Record the quotient 6 as the next digit in the result. 
Result so far: 876.0
Deduct 462 from 493 and we're left with 31.
Include the next digit (1) from the dividend after 31, then repeat: 311 / 77

Advancing to step 6:
77 goes into 311 4 times with a remainder of 3.
The next digit of our result is 4. 
Result so far: 8764.0
If we subtract 308 from 311, we get 3.
Take the next digit (5) from the dividend and append it to 3, then repeat: 35 / 77

Advancing to step 7:
77 can be fit into 35 0 times, resulting in a remainder of 35.
Write down 0 as next digit of the result. 
Result so far: 87640.0
If we take 0 away from 35, we end up with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 8:
If we divide 350 by 77, we get 4 and a remainder of 42.
Record the quotient 4 as the next digit in the result. 
Result so far: 87640.4
If we take 308 away from 350, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Let's proceed to step 9:
77 can be fit into 420 5 times, resulting in a remainder of 35.
Write down 5 as next digit of the result. 
Result so far: 87640.45
The remainder is 35 after subtracting 385 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Step 10:
77 goes into 350 4 times with a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 87640.454
If we subtract 308 from 350, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 11:
77 goes into 420 5 times with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 87640.4545
Deduct 385 from 420 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 12:
77 goes into 350 4 times with a remainder of 42.
Write down 4 as next digit of the result. 
Result so far: 87640.45454
Deduct 308 from 350 and we're left with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 13:
77 goes into 420 5 times with a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 87640.454545
Subtracting 385 from 420 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Let's proceed to step 14:
77 goes into 350 4 times with a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 87640.4545454
If we take 308 away from 350, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Moving on to step 15:
77 can be fit into 420 5 times, resulting in a remainder of 35.
The number 5 becomes the next digit in our result. 
Result so far: 87640.45454545
Deduct 385 from 420 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

The final result is 87640.45454545 with a remainder of 3.5e-08.
