77042009 divided by 816 
Let's see how many times 816 fits into 77042009.

Going ahead to step 1:
If we divide 7 by 816, we get 0 and a remainder of 7.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 7 leaves us with 7.
Grab the next digit (7) from the dividend, add it to 7, then carry on: 77 / 816

Advancing to step 2:
816 goes into 77 0 times with a remainder of 77.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Deduct 0 from 77 and we're left with 77.
Fetch the next digit (0) from the dividend, attach it to 77 and continue: 770 / 816

Advancing to step 3:
770 divided by 816 is 0 with a remainder of 770.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 770 and we're left with 770.
Fetch the next digit (4) from the dividend, attach it to 770 and continue: 7704 / 816

Moving on to step 4:
If we divide 7704 by 816, we get 9 and a remainder of 360.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 7344 from 7704, we get 360.
Bring next digit (2) of the dividend behind the 360 and repeat the process: 3602 / 816

Step 5:
3602 divided by 816 is 4 with a remainder of 338.
Write down 4 as next digit of the result. 
Result so far: 94.0
If we take 3264 away from 3602, we end up with 338.
Include the next digit (0) from the dividend after 338, then repeat: 3380 / 816

Step 6:
816 can be fit into 3380 4 times, resulting in a remainder of 116.
The next digit of our result is 4. 
Result so far: 944.0
Deduct 3264 from 3380 and we're left with 116.
Append the next digit (0) from the dividend to 116 and continue with: 1160 / 816

Moving on to step 7:
816 goes into 1160 1 times with a remainder of 344.
Put 1 as the next digit of the answer. 
Result so far: 9441.0
Deduct 816 from 1160 and we're left with 344.
Append the next digit (9) from the dividend to 344 and continue with: 3449 / 816

Advancing to step 8:
816 can be fit into 3449 4 times, resulting in a remainder of 185.
Put 4 as the next digit of the answer. 
Result so far: 94414.0
If we subtract 3264 from 3449, we get 185.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1850, and continue the process.

Going ahead to step 9:
When dividing 1850 by 816, we get 2 with a remainder of 218.
Use 2 as the next digit of our solution. 
Result so far: 94414.2
Subtracting 1632 from 1850 leaves us with 218.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2180, and continue the process.

Step 10:
816 can be fit into 2180 2 times, resulting in a remainder of 548.
Put 2 as the next digit of the answer. 
Result so far: 94414.22
Subtracting 1632 from 2180 leaves us with 548.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5480, and continue the process.

The final result is 94414.22 with a remainder of 0.548.
