We look at the division of 876861 by 77 
We want to figure out the number of times 876861 can be divided by 77.

Let's proceed to step 1:
If we divide 8 by 77, we get 0 and a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 8 and we're left with 8.
Grab the next digit (7) from the dividend, add it to 8, then carry on: 87 / 77

Going ahead to step 2:
77 can be fit into 87 1 times, resulting in a remainder of 10.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 77 from 87 and we're left with 10.
Append the next digit (6) from the dividend to 10 and continue with: 106 / 77

Advancing to step 3:
77 goes into 106 1 times with a remainder of 29.
Record the quotient 1 as the next digit in the result. 
Result so far: 11.0
Subtract 77 from 106 to get 29.
Bring next digit (8) of the dividend behind the 29 and repeat the process: 298 / 77

Going ahead to step 4:
If we divide 298 by 77, we get 3 and a remainder of 67.
Record the quotient 3 as the next digit in the result. 
Result so far: 113.0
Deduct 231 from 298 and we're left with 67.
Include the next digit (6) from the dividend after 67, then repeat: 676 / 77

Going ahead to step 5:
676 divided by 77 is 8 with a remainder of 60.
Write down 8 as next digit of the result. 
Result so far: 1138.0
Subtracting 616 from 676 leaves us with 60.
Append the next digit (1) from the dividend to 60 and continue with: 601 / 77

Step 6:
The number 77 fits into 601 7 times, leaving a remainder of 62.
The next digit of our result is 7. 
Result so far: 11387.0
If we take 539 away from 601, 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.

Going ahead to step 7:
When dividing 620 by 77, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 11387.8
If we take 616 away from 620, we end up 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.

Moving on to step 8:
40 divided by 77 is 0 with a remainder of 40.
The number 0 becomes the next digit in our result. 
Result so far: 11387.8
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

Advancing to step 9:
If we divide 400 by 77, we get 5 and a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 11387.805
If we take 385 away from 400, we end up with 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 10:
77 can be fit into 150 1 times, resulting in a remainder of 73.
Put 1 as the next digit of the answer. 
Result so far: 11387.8051
If we take 77 away from 150, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 11:
If we divide 730 by 77, we get 9 and a remainder of 37.
The next digit of our result is 9. 
Result so far: 11387.80519
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.

Step 12:
If we divide 370 by 77, we get 4 and a remainder of 62.
The number 4 becomes the next digit in our result. 
Result so far: 11387.805194
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.

Step 13:
When dividing 620 by 77, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 11387.8051948
The remainder is 4 after subtracting 616 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 14:
77 goes into 40 0 times with a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 11387.8051948
If we subtract 0 from 40, we get 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 400, and continue the process.

The final result is 11387.8051948 with a remainder of 4e-08.
