We look at the division of 76757871 by 879 
We want to divide 76757871 by 879.

On to step 1:
879 goes into 7 0 times with a remainder of 7.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Grab the next digit (6) from the dividend, add it to 7, then carry on: 76 / 879

On to step 2:
If we divide 76 by 879, we get 0 and a remainder of 76.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 76, we get 76.
Take the next digit (7) from the dividend and append it to 76, then repeat: 767 / 879

On to step 3:
If we divide 767 by 879, we get 0 and a remainder of 767.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 767 after subtracting 0 from 767.
Grab the next digit (5) from the dividend, add it to 767, then carry on: 7675 / 879

Going ahead to step 4:
7675 divided by 879 is 8 with a remainder of 643.
Write down 8 as next digit of the result. 
Result so far: 8.0
Deduct 7032 from 7675 and we're left with 643.
Include the next digit (7) from the dividend after 643, then repeat: 6437 / 879

Moving on to step 5:
879 can be fit into 6437 7 times, resulting in a remainder of 284.
Write down 7 as next digit of the result. 
Result so far: 87.0
If we subtract 6153 from 6437, we get 284.
Fetch the next digit (8) from the dividend, attach it to 284 and continue: 2848 / 879

Advancing to step 6:
879 can be fit into 2848 3 times, resulting in a remainder of 211.
Put 3 as the next digit of the answer. 
Result so far: 873.0
The remainder is 211 after subtracting 2637 from 2848.
Append the next digit (7) from the dividend to 211 and continue with: 2117 / 879

Step 7:
2117 divided by 879 is 2 with a remainder of 359.
Put 2 as the next digit of the answer. 
Result so far: 8732.0
If we subtract 1758 from 2117, we get 359.
Fetch the next digit (1) from the dividend, attach it to 359 and continue: 3591 / 879

Going ahead to step 8:
879 can be fit into 3591 4 times, resulting in a remainder of 75.
Write down 4 as next digit of the result. 
Result so far: 87324.0
Deduct 3516 from 3591 and we're left 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.

Step 9:
879 can be fit into 750 0 times, resulting in a remainder of 750.
Put 0 as the next digit of the answer. 
Result so far: 87324.0
Subtracting 0 from 750 leaves us with 750.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7500, and continue the process.

Moving on to step 10:
879 goes into 7500 8 times with a remainder of 468.
Put 8 as the next digit of the answer. 
Result so far: 87324.08
Subtract 7032 from 7500 to get 468.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4680, and continue the process.

On to step 11:
4680 divided by 879 is 5 with a remainder of 285.
The next digit of our result is 5. 
Result so far: 87324.085
If we subtract 4395 from 4680, we get 285.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2850, and continue the process.

Step 12:
2850 divided by 879 is 3 with a remainder of 213.
The next digit of our result is 3. 
Result so far: 87324.0853
If we subtract 2637 from 2850, we get 213.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2130, and continue the process.

Moving on to step 13:
879 goes into 2130 2 times with a remainder of 372.
The number 2 becomes the next digit in our result. 
Result so far: 87324.08532
Deduct 1758 from 2130 and we're left with 372.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3720, and continue the process.

On to step 14:
If we divide 3720 by 879, we get 4 and a remainder of 204.
The number 4 becomes the next digit in our result. 
Result so far: 87324.085324
The remainder is 204 after subtracting 3516 from 3720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2040, and continue the process.

Going ahead to step 15:
When dividing 2040 by 879, we get 2 with a remainder of 282.
The number 2 becomes the next digit in our result. 
Result so far: 87324.0853242
The remainder is 282 after subtracting 1758 from 2040.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2820, and continue the process.

Let's proceed to step 16:
If we divide 2820 by 879, we get 3 and a remainder of 183.
The next digit of our result is 3. 
Result so far: 87324.08532423
Subtract 2637 from 2820 to get 183.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1830, and continue the process.

The final outcome is 87324.08532423, with a leftover of 1.83e-07.
