We divide 77661445 by 809
We want to figure out the number of times 77661445 can be divided by 809.

Advancing to step 1:
809 goes into 7 0 times with a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we take 0 away from 7, we end up with 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 809

Step 2:
809 can be fit into 77 0 times, resulting in a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 77 to get 77.
Grab the next digit (6) from the dividend, add it to 77, then carry on: 776 / 809

Going ahead to step 3:
809 can be fit into 776 0 times, resulting in a remainder of 776.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 776, we get 776.
Grab the next digit (6) from the dividend, add it to 776, then carry on: 7766 / 809

Let's proceed to step 4:
809 can be fit into 7766 9 times, resulting in a remainder of 485.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we subtract 7281 from 7766, we get 485.
Bring next digit (1) of the dividend behind the 485 and repeat the process: 4851 / 809

Moving on to step 5:
809 can be fit into 4851 5 times, resulting in a remainder of 806.
The number 5 becomes the next digit in our result. 
Result so far: 95.0
Subtract 4045 from 4851 to get 806.
Append the next digit (4) from the dividend to 806 and continue with: 8064 / 809

Let's proceed to step 6:
8064 divided by 809 is 9 with a remainder of 783.
Write down 9 as next digit of the result. 
Result so far: 959.0
Subtract 7281 from 8064 to get 783.
Grab the next digit (4) from the dividend, add it to 783, then carry on: 7834 / 809

On to step 7:
When dividing 7834 by 809, we get 9 with a remainder of 553.
Put 9 as the next digit of the answer. 
Result so far: 9599.0
Subtracting 7281 from 7834 leaves us with 553.
Append the next digit (5) from the dividend to 553 and continue with: 5535 / 809

On to step 8:
809 goes into 5535 6 times with a remainder of 681.
The next digit of our result is 6. 
Result so far: 95996.0
If we take 4854 away from 5535, we end up with 681.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6810, and continue the process.

Moving on to step 9:
The number 809 fits into 6810 8 times, leaving a remainder of 338.
The number 8 becomes the next digit in our result. 
Result so far: 95996.8
If we take 6472 away from 6810, we end up with 338.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3380, and continue the process.

Advancing to step 10:
3380 divided by 809 is 4 with a remainder of 144.
The next digit of our result is 4. 
Result so far: 95996.84
If we subtract 3236 from 3380, we get 144.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1440, and continue the process.

Moving on to step 11:
If we divide 1440 by 809, we get 1 and a remainder of 631.
Use 1 as the next digit of our solution. 
Result so far: 95996.841
The remainder is 631 after subtracting 809 from 1440.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6310, and continue the process.

Going ahead to step 12:
When dividing 6310 by 809, we get 7 with a remainder of 647.
Record the quotient 7 as the next digit in the result. 
Result so far: 95996.8417
If we take 5663 away from 6310, we end up with 647.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6470, and continue the process.

Step 13:
809 goes into 6470 7 times with a remainder of 807.
Use 7 as the next digit of our solution. 
Result so far: 95996.84177
Subtracting 5663 from 6470 leaves us with 807.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8070, and continue the process.

In conclusion, the division gives 95996.84177 with a balance of 0.000807.
