We're dividing 78374262 by 851 
Let's see how many times 851 fits into 78374262.

Going ahead to step 1:
If we divide 7 by 851, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 851

Let's proceed to step 2:
The number 851 fits into 78 0 times, leaving a remainder of 78.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 78 leaves us with 78.
Fetch the next digit (3) from the dividend, attach it to 78 and continue: 783 / 851

On to step 3:
If we divide 783 by 851, we get 0 and a remainder of 783.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 783, we end up with 783.
Append the next digit (7) from the dividend to 783 and continue with: 7837 / 851

Moving on to step 4:
7837 divided by 851 is 9 with a remainder of 178.
The next digit of our result is 9. 
Result so far: 9.0
If we take 7659 away from 7837, we end up with 178.
Take the next digit (4) from the dividend and append it to 178, then repeat: 1784 / 851

Step 5:
The number 851 fits into 1784 2 times, leaving a remainder of 82.
Put 2 as the next digit of the answer. 
Result so far: 92.0
Subtract 1702 from 1784 to get 82.
Fetch the next digit (2) from the dividend, attach it to 82 and continue: 822 / 851

On to step 6:
When dividing 822 by 851, we get 0 with a remainder of 822.
The next digit of our result is 0. 
Result so far: 920.0
If we subtract 0 from 822, we get 822.
Grab the next digit (6) from the dividend, add it to 822, then carry on: 8226 / 851

Advancing to step 7:
The number 851 fits into 8226 9 times, leaving a remainder of 567.
Record the quotient 9 as the next digit in the result. 
Result so far: 9209.0
The remainder is 567 after subtracting 7659 from 8226.
Grab the next digit (2) from the dividend, add it to 567, then carry on: 5672 / 851

Moving on to step 8:
851 goes into 5672 6 times with a remainder of 566.
The number 6 becomes the next digit in our result. 
Result so far: 92096.0
Deduct 5106 from 5672 and we're left with 566.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5660, and continue the process.

Step 9:
When dividing 5660 by 851, we get 6 with a remainder of 554.
Use 6 as the next digit of our solution. 
Result so far: 92096.6
If we subtract 5106 from 5660, we get 554.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5540, and continue the process.

Going ahead to step 10:
If we divide 5540 by 851, we get 6 and a remainder of 434.
Record the quotient 6 as the next digit in the result. 
Result so far: 92096.66
The remainder is 434 after subtracting 5106 from 5540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4340, and continue the process.

In conclusion, the division gives 92096.66 with a balance of 0.434.
