77718374 ÷ 497 
Our goal is to divide 77718374 by 497.

Going ahead to step 1:
When dividing 7 by 497, we get 0 with a remainder of 7.
Record the quotient 0 as the next digit in the result. 
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 / 497

Step 2:
77 divided by 497 is 0 with a remainder of 77.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 77 leaves us with 77.
Fetch the next digit (7) from the dividend, attach it to 77 and continue: 777 / 497

Let's proceed to step 3:
497 goes into 777 1 times with a remainder of 280.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 497 from 777 leaves us with 280.
Take the next digit (1) from the dividend and append it to 280, then repeat: 2801 / 497

On to step 4:
2801 divided by 497 is 5 with a remainder of 316.
Write down 5 as next digit of the result. 
Result so far: 15.0
Subtract 2485 from 2801 to get 316.
Include the next digit (8) from the dividend after 316, then repeat: 3168 / 497

Going ahead to step 5:
497 goes into 3168 6 times with a remainder of 186.
Use 6 as the next digit of our solution. 
Result so far: 156.0
Subtracting 2982 from 3168 leaves us with 186.
Include the next digit (3) from the dividend after 186, then repeat: 1863 / 497

Moving on to step 6:
When dividing 1863 by 497, we get 3 with a remainder of 372.
Write down 3 as next digit of the result. 
Result so far: 1563.0
If we take 1491 away from 1863, we end up with 372.
Bring next digit (7) of the dividend behind the 372 and repeat the process: 3727 / 497

Let's proceed to step 7:
497 goes into 3727 7 times with a remainder of 248.
Use 7 as the next digit of our solution. 
Result so far: 15637.0
Subtracting 3479 from 3727 leaves us with 248.
Fetch the next digit (4) from the dividend, attach it to 248 and continue: 2484 / 497

Going ahead to step 8:
If we divide 2484 by 497, we get 4 and a remainder of 496.
The next digit of our result is 4. 
Result so far: 156374.0
If we subtract 1988 from 2484, we get 496.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4960, and continue the process.

Step 9:
The number 497 fits into 4960 9 times, leaving a remainder of 487.
Record the quotient 9 as the next digit in the result. 
Result so far: 156374.9
If we take 4473 away from 4960, we end up with 487.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4870, and continue the process.

On to step 10:
497 goes into 4870 9 times with a remainder of 397.
Record the quotient 9 as the next digit in the result. 
Result so far: 156374.99
If we take 4473 away from 4870, we end up with 397.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3970, and continue the process.

Our division results in 156374.99 with a remaining 0.397.
