850856 divided by 78 
We want to divide 850856 by 78.

Step 1:
The number 78 fits into 8 0 times, leaving a remainder of 8.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtracting 0 from 8 leaves us with 8.
Take the next digit (5) from the dividend and append it to 8, then repeat: 85 / 78

Step 2:
78 goes into 85 1 times with a remainder of 7.
The next digit of our result is 1. 
Result so far: 1.0
Subtract 78 from 85 to get 7.
Bring next digit (0) of the dividend behind the 7 and repeat the process: 70 / 78

Let's proceed to step 3:
70 divided by 78 is 0 with a remainder of 70.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
Subtracting 0 from 70 leaves us with 70.
Take the next digit (8) from the dividend and append it to 70, then repeat: 708 / 78

Going ahead to step 4:
When dividing 708 by 78, we get 9 with a remainder of 6.
Record the quotient 9 as the next digit in the result. 
Result so far: 109.0
Deduct 702 from 708 and we're left with 6.
Include the next digit (5) from the dividend after 6, then repeat: 65 / 78

Step 5:
78 goes into 65 0 times with a remainder of 65.
The next digit of our result is 0. 
Result so far: 1090.0
Subtracting 0 from 65 leaves us with 65.
Grab the next digit (6) from the dividend, add it to 65, then carry on: 656 / 78

Advancing to step 6:
78 goes into 656 8 times with a remainder of 32.
Use 8 as the next digit of our solution. 
Result so far: 10908.0
If we subtract 624 from 656, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 7:
When dividing 320 by 78, we get 4 with a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 10908.4
If we subtract 312 from 320, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Going ahead to step 8:
80 divided by 78 is 1 with a remainder of 2.
Use 1 as the next digit of our solution. 
Result so far: 10908.41
Subtract 78 from 80 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 9:
78 can be fit into 20 0 times, resulting in a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 10908.41
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 10:
The number 78 fits into 200 2 times, leaving a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 10908.4102
If we subtract 156 from 200, 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 11:
When dividing 440 by 78, we get 5 with a remainder of 50.
Record the quotient 5 as the next digit in the result. 
Result so far: 10908.41025
The remainder is 50 after subtracting 390 from 440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Moving on to step 12:
If we divide 500 by 78, we get 6 and a remainder of 32.
The number 6 becomes the next digit in our result. 
Result so far: 10908.410256
The remainder is 32 after subtracting 468 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 13:
If we divide 320 by 78, we get 4 and a remainder of 8.
Put 4 as the next digit of the answer. 
Result so far: 10908.4102564
Subtracting 312 from 320 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 14:
If we divide 80 by 78, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 10908.41025641
Deduct 78 from 80 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 10908.41025641, with a leftover of 2e-09.
