7897766 ÷ 805 
We want to figure out the number of times 7897766 can be divided by 805.

Let's proceed to step 1:
805 can be fit into 7 0 times, resulting in a remainder of 7.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Fetch the next digit (8) from the dividend, attach it to 7 and continue: 78 / 805

Moving on to step 2:
When dividing 78 by 805, we get 0 with a remainder of 78.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 78, we end up with 78.
Bring next digit (9) of the dividend behind the 78 and repeat the process: 789 / 805

Step 3:
The number 805 fits into 789 0 times, leaving a remainder of 789.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 789, we get 789.
Include the next digit (7) from the dividend after 789, then repeat: 7897 / 805

Step 4:
805 goes into 7897 9 times with a remainder of 652.
The next digit of our result is 9. 
Result so far: 9.0
Subtracting 7245 from 7897 leaves us with 652.
Bring next digit (7) of the dividend behind the 652 and repeat the process: 6527 / 805

Let's proceed to step 5:
The number 805 fits into 6527 8 times, leaving a remainder of 87.
The number 8 becomes the next digit in our result. 
Result so far: 98.0
Deduct 6440 from 6527 and we're left with 87.
Bring next digit (6) of the dividend behind the 87 and repeat the process: 876 / 805

Let's proceed to step 6:
When dividing 876 by 805, we get 1 with a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 981.0
If we subtract 805 from 876, we get 71.
Grab the next digit (6) from the dividend, add it to 71, then carry on: 716 / 805

On to step 7:
The number 805 fits into 716 0 times, leaving a remainder of 716.
Record the quotient 0 as the next digit in the result. 
Result so far: 9810.0
If we subtract 0 from 716, we get 716.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7160, and continue the process.

Going ahead to step 8:
7160 divided by 805 is 8 with a remainder of 720.
Write down 8 as next digit of the result. 
Result so far: 9810.8
The remainder is 720 after subtracting 6440 from 7160.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7200, and continue the process.

Going ahead to step 9:
When dividing 7200 by 805, we get 8 with a remainder of 760.
Record the quotient 8 as the next digit in the result. 
Result so far: 9810.88
If we take 6440 away from 7200, we end up with 760.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7600, and continue the process.

Our division results in 9810.88 with a remaining 0.76.
