77756137 divided by 816 
We want to figure out the number of times 77756137 can be divided by 816.

On 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
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 / 816

On to step 2:
The number 816 fits into 77 0 times, leaving a remainder of 77.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Include the next digit (7) from the dividend after 77, then repeat: 777 / 816

Advancing to step 3:
The number 816 fits into 777 0 times, leaving a remainder of 777.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 777, we end up with 777.
Fetch the next digit (5) from the dividend, attach it to 777 and continue: 7775 / 816

Moving on to step 4:
When dividing 7775 by 816, we get 9 with a remainder of 431.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
The remainder is 431 after subtracting 7344 from 7775.
Include the next digit (6) from the dividend after 431, then repeat: 4316 / 816

Going ahead to step 5:
The number 816 fits into 4316 5 times, leaving a remainder of 236.
The next digit of our result is 5. 
Result so far: 95.0
The remainder is 236 after subtracting 4080 from 4316.
Include the next digit (1) from the dividend after 236, then repeat: 2361 / 816

Going ahead to step 6:
The number 816 fits into 2361 2 times, leaving a remainder of 729.
Put 2 as the next digit of the answer. 
Result so far: 952.0
If we take 1632 away from 2361, we end up with 729.
Take the next digit (3) from the dividend and append it to 729, then repeat: 7293 / 816

Advancing to step 7:
816 goes into 7293 8 times with a remainder of 765.
The next digit of our result is 8. 
Result so far: 9528.0
If we subtract 6528 from 7293, we get 765.
Append the next digit (7) from the dividend to 765 and continue with: 7657 / 816

Moving on to step 8:
7657 divided by 816 is 9 with a remainder of 313.
Use 9 as the next digit of our solution. 
Result so far: 95289.0
If we take 7344 away from 7657, we end up with 313.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3130, and continue the process.

Moving on to step 9:
The number 816 fits into 3130 3 times, leaving a remainder of 682.
Use 3 as the next digit of our solution. 
Result so far: 95289.3
If we take 2448 away from 3130, we end up with 682.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6820, and continue the process.

On to step 10:
816 can be fit into 6820 8 times, resulting in a remainder of 292.
The number 8 becomes the next digit in our result. 
Result so far: 95289.38
If we subtract 6528 from 6820, we get 292.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2920, and continue the process.

Advancing to step 11:
The number 816 fits into 2920 3 times, leaving a remainder of 472.
Use 3 as the next digit of our solution. 
Result so far: 95289.383
Subtracting 2448 from 2920 leaves us with 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Moving on to step 12:
When dividing 4720 by 816, we get 5 with a remainder of 640.
Record the quotient 5 as the next digit in the result. 
Result so far: 95289.3835
If we take 4080 away from 4720, we end up with 640.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6400, and continue the process.

Step 13:
When dividing 6400 by 816, we get 7 with a remainder of 688.
Put 7 as the next digit of the answer. 
Result so far: 95289.38357
Deduct 5712 from 6400 and we're left with 688.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6880, and continue the process.

Advancing to step 14:
6880 divided by 816 is 8 with a remainder of 352.
Put 8 as the next digit of the answer. 
Result so far: 95289.383578
The remainder is 352 after subtracting 6528 from 6880.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

Going ahead to step 15:
The number 816 fits into 3520 4 times, leaving a remainder of 256.
Write down 4 as next digit of the result. 
Result so far: 95289.3835784
If we subtract 3264 from 3520, we get 256.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

Step 16:
When dividing 2560 by 816, we get 3 with a remainder of 112.
Write down 3 as next digit of the result. 
Result so far: 95289.38357843
Subtract 2448 from 2560 to get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

After the division, we end up with 95289.38357843 and a remainder of 1.12e-07.
