78829426 divided by 850 
We want to divide 78829426 by 850.

Moving on to step 1:
850 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
Subtract 0 from 7 to get 7.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 850

Going ahead to step 2:
850 goes into 78 0 times with a remainder of 78.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 78 after subtracting 0 from 78.
Grab the next digit (8) from the dividend, add it to 78, then carry on: 788 / 850

Going ahead to step 3:
If we divide 788 by 850, we get 0 and a remainder of 788.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 788 leaves us with 788.
Grab the next digit (2) from the dividend, add it to 788, then carry on: 7882 / 850

Going ahead to step 4:
7882 divided by 850 is 9 with a remainder of 232.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we take 7650 away from 7882, we end up with 232.
Include the next digit (9) from the dividend after 232, then repeat: 2329 / 850

Moving on to step 5:
850 goes into 2329 2 times with a remainder of 629.
The number 2 becomes the next digit in our result. 
Result so far: 92.0
Subtracting 1700 from 2329 leaves us with 629.
Grab the next digit (4) from the dividend, add it to 629, then carry on: 6294 / 850

Step 6:
850 goes into 6294 7 times with a remainder of 344.
Write down 7 as next digit of the result. 
Result so far: 927.0
Subtracting 5950 from 6294 leaves us with 344.
Bring next digit (2) of the dividend behind the 344 and repeat the process: 3442 / 850

Going ahead to step 7:
If we divide 3442 by 850, we get 4 and a remainder of 42.
The number 4 becomes the next digit in our result. 
Result so far: 9274.0
The remainder is 42 after subtracting 3400 from 3442.
Grab the next digit (6) from the dividend, add it to 42, then carry on: 426 / 850

On to step 8:
426 divided by 850 is 0 with a remainder of 426.
The number 0 becomes the next digit in our result. 
Result so far: 92740.0
Subtracting 0 from 426 leaves us with 426.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4260, and continue the process.

Let's proceed to step 9:
When dividing 4260 by 850, we get 5 with a remainder of 10.
The number 5 becomes the next digit in our result. 
Result so far: 92740.5
The remainder is 10 after subtracting 4250 from 4260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 10:
100 divided by 850 is 0 with a remainder of 100.
Write down 0 as next digit of the result. 
Result so far: 92740.5
The remainder is 100 after subtracting 0 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1000, and continue the process.

Advancing to step 11:
850 goes into 1000 1 times with a remainder of 150.
Put 1 as the next digit of the answer. 
Result so far: 92740.501
The remainder is 150 after subtracting 850 from 1000.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1500, and continue the process.

Advancing to step 12:
1500 divided by 850 is 1 with a remainder of 650.
Put 1 as the next digit of the answer. 
Result so far: 92740.5011
Deduct 850 from 1500 and we're left with 650.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6500, and continue the process.

The final result is 92740.5011 with a remainder of 0.0065.
