78653879 ÷ 856 
We want to divide 78653879 by 856.

Advancing to step 1:
The number 856 fits into 7 0 times, leaving a remainder of 7.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 7 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 856

Step 2:
When dividing 78 by 856, we get 0 with a remainder of 78.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 78, we get 78.
Include the next digit (6) from the dividend after 78, then repeat: 786 / 856

Advancing to step 3:
If we divide 786 by 856, we get 0 and a remainder of 786.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 786 to get 786.
Take the next digit (5) from the dividend and append it to 786, then repeat: 7865 / 856

Step 4:
856 goes into 7865 9 times with a remainder of 161.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 7704 from 7865 leaves us with 161.
Bring next digit (3) of the dividend behind the 161 and repeat the process: 1613 / 856

Step 5:
1613 divided by 856 is 1 with a remainder of 757.
Write down 1 as next digit of the result. 
Result so far: 91.0
If we subtract 856 from 1613, we get 757.
Fetch the next digit (8) from the dividend, attach it to 757 and continue: 7578 / 856

Moving on to step 6:
856 can be fit into 7578 8 times, resulting in a remainder of 730.
The number 8 becomes the next digit in our result. 
Result so far: 918.0
Subtract 6848 from 7578 to get 730.
Append the next digit (7) from the dividend to 730 and continue with: 7307 / 856

Going ahead to step 7:
856 can be fit into 7307 8 times, resulting in a remainder of 459.
The number 8 becomes the next digit in our result. 
Result so far: 9188.0
Subtract 6848 from 7307 to get 459.
Append the next digit (9) from the dividend to 459 and continue with: 4599 / 856

Step 8:
856 can be fit into 4599 5 times, resulting in a remainder of 319.
The number 5 becomes the next digit in our result. 
Result so far: 91885.0
Deduct 4280 from 4599 and we're left with 319.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3190, and continue the process.

Moving on to step 9:
856 goes into 3190 3 times with a remainder of 622.
The next digit of our result is 3. 
Result so far: 91885.3
Subtracting 2568 from 3190 leaves us with 622.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6220, and continue the process.

Step 10:
When dividing 6220 by 856, we get 7 with a remainder of 228.
Write down 7 as next digit of the result. 
Result so far: 91885.37
If we subtract 5992 from 6220, we get 228.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2280, and continue the process.

Moving on to step 11:
856 can be fit into 2280 2 times, resulting in a remainder of 568.
The next digit of our result is 2. 
Result so far: 91885.372
If we take 1712 away from 2280, we end up with 568.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5680, and continue the process.

Going ahead to step 12:
5680 divided by 856 is 6 with a remainder of 544.
Use 6 as the next digit of our solution. 
Result so far: 91885.3726
The remainder is 544 after subtracting 5136 from 5680.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5440, and continue the process.

Step 13:
5440 divided by 856 is 6 with a remainder of 304.
Write down 6 as next digit of the result. 
Result so far: 91885.37266
The remainder is 304 after subtracting 5136 from 5440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3040, and continue the process.

In conclusion, the division gives 91885.37266 with a balance of 0.000304.
