We're dividing 77511561 by 826 
Let's see how many times 826 fits into 77511561.

On to step 1:
7 divided by 826 is 0 with a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
The remainder is 7 after subtracting 0 from 7.
Include the next digit (7) from the dividend after 7, then repeat: 77 / 826

Advancing to step 2:
The number 826 fits into 77 0 times, leaving a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 77, we get 77.
Take the next digit (5) from the dividend and append it to 77, then repeat: 775 / 826

Advancing to step 3:
826 can be fit into 775 0 times, resulting in a remainder of 775.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 775 leaves us with 775.
Append the next digit (1) from the dividend to 775 and continue with: 7751 / 826

Let's proceed to step 4:
When dividing 7751 by 826, we get 9 with a remainder of 317.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtract 7434 from 7751 to get 317.
Include the next digit (1) from the dividend after 317, then repeat: 3171 / 826

Going ahead to step 5:
826 can be fit into 3171 3 times, resulting in a remainder of 693.
The number 3 becomes the next digit in our result. 
Result so far: 93.0
Deduct 2478 from 3171 and we're left with 693.
Include the next digit (5) from the dividend after 693, then repeat: 6935 / 826

Step 6:
826 can be fit into 6935 8 times, resulting in a remainder of 327.
Put 8 as the next digit of the answer. 
Result so far: 938.0
Subtracting 6608 from 6935 leaves us with 327.
Grab the next digit (6) from the dividend, add it to 327, then carry on: 3276 / 826

Going ahead to step 7:
The number 826 fits into 3276 3 times, leaving a remainder of 798.
Record the quotient 3 as the next digit in the result. 
Result so far: 9383.0
If we take 2478 away from 3276, we end up with 798.
Take the next digit (1) from the dividend and append it to 798, then repeat: 7981 / 826

Moving on to step 8:
826 goes into 7981 9 times with a remainder of 547.
Record the quotient 9 as the next digit in the result. 
Result so far: 93839.0
If we subtract 7434 from 7981, we get 547.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5470, and continue the process.

Step 9:
If we divide 5470 by 826, we get 6 and a remainder of 514.
Use 6 as the next digit of our solution. 
Result so far: 93839.6
Deduct 4956 from 5470 and we're left with 514.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5140, and continue the process.

Let's proceed to step 10:
The number 826 fits into 5140 6 times, leaving a remainder of 184.
Record the quotient 6 as the next digit in the result. 
Result so far: 93839.66
Deduct 4956 from 5140 and we're left with 184.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1840, and continue the process.

The final result is 93839.66 with a remainder of 0.184.
