77855726 ÷ 851 
Let's see how many times 851 fits into 77855726.

Moving on to step 1:
The number 851 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
If we subtract 0 from 7, we get 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 851

Step 2:
77 divided by 851 is 0 with a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 77, we end up with 77.
Append the next digit (8) from the dividend to 77 and continue with: 778 / 851

Step 3:
The number 851 fits into 778 0 times, leaving a remainder of 778.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 778 leaves us with 778.
Grab the next digit (5) from the dividend, add it to 778, then carry on: 7785 / 851

Going ahead to step 4:
The number 851 fits into 7785 9 times, leaving a remainder of 126.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 7659 from 7785 to get 126.
Include the next digit (5) from the dividend after 126, then repeat: 1265 / 851

Let's proceed to step 5:
1265 divided by 851 is 1 with a remainder of 414.
Put 1 as the next digit of the answer. 
Result so far: 91.0
If we take 851 away from 1265, we end up with 414.
Include the next digit (7) from the dividend after 414, then repeat: 4147 / 851

Step 6:
851 can be fit into 4147 4 times, resulting in a remainder of 743.
Use 4 as the next digit of our solution. 
Result so far: 914.0
If we take 3404 away from 4147, we end up with 743.
Include the next digit (2) from the dividend after 743, then repeat: 7432 / 851

Going ahead to step 7:
7432 divided by 851 is 8 with a remainder of 624.
Write down 8 as next digit of the result. 
Result so far: 9148.0
Deduct 6808 from 7432 and we're left with 624.
Fetch the next digit (6) from the dividend, attach it to 624 and continue: 6246 / 851

Advancing to step 8:
If we divide 6246 by 851, we get 7 and a remainder of 289.
Record the quotient 7 as the next digit in the result. 
Result so far: 91487.0
Subtracting 5957 from 6246 leaves us with 289.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2890, and continue the process.

On to step 9:
If we divide 2890 by 851, we get 3 and a remainder of 337.
Use 3 as the next digit of our solution. 
Result so far: 91487.3
If we subtract 2553 from 2890, we get 337.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3370, and continue the process.

Moving on to step 10:
If we divide 3370 by 851, we get 3 and a remainder of 817.
The number 3 becomes the next digit in our result. 
Result so far: 91487.33
Subtracting 2553 from 3370 leaves us with 817.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8170, and continue the process.

The quotient of the division is 91487.33, and the remainder is 0.817.
