We're dividing 497722 by 77 
The aim is to understand the frequency of 77 in 497722.

On to step 1:
If we divide 4 by 77, we get 0 and a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Include the next digit (9) from the dividend after 4, then repeat: 49 / 77

Moving on to step 2:
77 can be fit into 49 0 times, resulting in a remainder of 49.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 49, we get 49.
Take the next digit (7) from the dividend and append it to 49, then repeat: 497 / 77

On to step 3:
If we divide 497 by 77, we get 6 and a remainder of 35.
Write down 6 as next digit of the result. 
Result so far: 6.0
Deduct 462 from 497 and we're left with 35.
Fetch the next digit (7) from the dividend, attach it to 35 and continue: 357 / 77

Advancing to step 4:
77 goes into 357 4 times with a remainder of 49.
Put 4 as the next digit of the answer. 
Result so far: 64.0
The remainder is 49 after subtracting 308 from 357.
Take the next digit (2) from the dividend and append it to 49, then repeat: 492 / 77

Let's proceed to step 5:
492 divided by 77 is 6 with a remainder of 30.
Use 6 as the next digit of our solution. 
Result so far: 646.0
Subtract 462 from 492 to get 30.
Bring next digit (2) of the dividend behind the 30 and repeat the process: 302 / 77

Going ahead to step 6:
If we divide 302 by 77, we get 3 and a remainder of 71.
The next digit of our result is 3. 
Result so far: 6463.0
The remainder is 71 after subtracting 231 from 302.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 7:
If we divide 710 by 77, we get 9 and a remainder of 17.
The next digit of our result is 9. 
Result so far: 6463.9
Subtract 693 from 710 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 8:
77 goes into 170 2 times with a remainder of 16.
Use 2 as the next digit of our solution. 
Result so far: 6463.92
Subtracting 154 from 170 leaves us with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 9:
The number 77 fits into 160 2 times, leaving a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 6463.922
Subtract 154 from 160 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

The quotient of the division is 6463.922, and the remainder is 0.0006.
