878691 divided by 77 
We want to figure out the number of times 878691 can be divided by 77.

On to step 1:
77 can be fit into 8 0 times, resulting in a remainder of 8.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 8 after subtracting 0 from 8.
Bring next digit (7) of the dividend behind the 8 and repeat the process: 87 / 77

Moving on to step 2:
77 can be fit into 87 1 times, resulting in a remainder of 10.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we subtract 77 from 87, we get 10.
Append the next digit (8) from the dividend to 10 and continue with: 108 / 77

Step 3:
108 divided by 77 is 1 with a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 11.0
Subtract 77 from 108 to get 31.
Append the next digit (6) from the dividend to 31 and continue with: 316 / 77

Moving on to step 4:
316 divided by 77 is 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 114.0
Subtract 308 from 316 to get 8.
Take the next digit (9) from the dividend and append it to 8, then repeat: 89 / 77

Advancing to step 5:
If we divide 89 by 77, we get 1 and a remainder of 12.
Put 1 as the next digit of the answer. 
Result so far: 1141.0
Deduct 77 from 89 and we're left with 12.
Take the next digit (1) from the dividend and append it to 12, then repeat: 121 / 77

Going ahead to step 6:
If we divide 121 by 77, we get 1 and a remainder of 44.
The number 1 becomes the next digit in our result. 
Result so far: 11411.0
If we subtract 77 from 121, we get 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Going ahead to step 7:
If we divide 440 by 77, we get 5 and a remainder of 55.
Use 5 as the next digit of our solution. 
Result so far: 11411.5
The remainder is 55 after subtracting 385 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Moving on to step 8:
When dividing 550 by 77, we get 7 with a remainder of 11.
Put 7 as the next digit of the answer. 
Result so far: 11411.57
Subtracting 539 from 550 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

On to step 9:
The number 77 fits into 110 1 times, leaving a remainder of 33.
Record the quotient 1 as the next digit in the result. 
Result so far: 11411.571
Subtract 77 from 110 to get 33.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

On to step 10:
The number 77 fits into 330 4 times, leaving a remainder of 22.
Write down 4 as next digit of the result. 
Result so far: 11411.5714
Subtracting 308 from 330 leaves us with 22.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Advancing to step 11:
The number 77 fits into 220 2 times, leaving a remainder of 66.
The number 2 becomes the next digit in our result. 
Result so far: 11411.57142
Deduct 154 from 220 and we're left with 66.
Since there are no more digits in the dividend, we add a zero to the remainder making it 660, and continue the process.

On to step 12:
77 can be fit into 660 8 times, resulting in a remainder of 44.
Write down 8 as next digit of the result. 
Result so far: 11411.571428
Subtracting 616 from 660 leaves us with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Moving on to step 13:
The number 77 fits into 440 5 times, leaving a remainder of 55.
The number 5 becomes the next digit in our result. 
Result so far: 11411.5714285
If we take 385 away from 440, we end up with 55.
Since there are no more digits in the dividend, we add a zero to the remainder making it 550, and continue the process.

Step 14:
550 divided by 77 is 7 with a remainder of 11.
The number 7 becomes the next digit in our result. 
Result so far: 11411.57142857
Subtracting 539 from 550 leaves us with 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

The final result is 11411.57142857 with a remainder of 1.1e-08.
