77622413 ÷ 774 
Our goal is to divide 77622413 by 774.

Going ahead to step 1:
If we divide 7 by 774, we get 0 and a remainder of 7.
Use 0 as the next digit of our solution. 
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 / 774

Going ahead to step 2:
The number 774 fits into 77 0 times, leaving a remainder of 77.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Fetch the next digit (6) from the dividend, attach it to 77 and continue: 776 / 774

Step 3:
776 divided by 774 is 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 2 after subtracting 774 from 776.
Include the next digit (2) from the dividend after 2, then repeat: 22 / 774

Going ahead to step 4:
774 can be fit into 22 0 times, resulting in a remainder of 22.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 22, we end up with 22.
Fetch the next digit (2) from the dividend, attach it to 22 and continue: 222 / 774

Step 5:
774 goes into 222 0 times with a remainder of 222.
The number 0 becomes the next digit in our result. 
Result so far: 100.0
Deduct 0 from 222 and we're left with 222.
Take the next digit (4) from the dividend and append it to 222, then repeat: 2224 / 774

Advancing to step 6:
If we divide 2224 by 774, we get 2 and a remainder of 676.
Put 2 as the next digit of the answer. 
Result so far: 1002.0
Subtract 1548 from 2224 to get 676.
Fetch the next digit (1) from the dividend, attach it to 676 and continue: 6761 / 774

Let's proceed to step 7:
The number 774 fits into 6761 8 times, leaving a remainder of 569.
The next digit of our result is 8. 
Result so far: 10028.0
If we take 6192 away from 6761, we end up with 569.
Fetch the next digit (3) from the dividend, attach it to 569 and continue: 5693 / 774

Moving on to step 8:
774 goes into 5693 7 times with a remainder of 275.
Write down 7 as next digit of the result. 
Result so far: 100287.0
Subtract 5418 from 5693 to get 275.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2750, and continue the process.

On to step 9:
774 goes into 2750 3 times with a remainder of 428.
Write down 3 as next digit of the result. 
Result so far: 100287.3
Subtract 2322 from 2750 to get 428.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4280, and continue the process.

Advancing to step 10:
4280 divided by 774 is 5 with a remainder of 410.
The next digit of our result is 5. 
Result so far: 100287.35
Subtract 3870 from 4280 to get 410.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4100, and continue the process.

Going ahead to step 11:
774 goes into 4100 5 times with a remainder of 230.
Use 5 as the next digit of our solution. 
Result so far: 100287.355
If we take 3870 away from 4100, we end up with 230.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2300, and continue the process.

The final outcome is 100287.355, with a leftover of 0.023.
