623760 ÷ 77 
The aim is to understand the frequency of 77 in 623760.

Moving on to step 1:
When dividing 6 by 77, we get 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 77

Advancing to step 2:
The number 77 fits into 62 0 times, leaving a remainder of 62.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 62, we end up with 62.
Fetch the next digit (3) from the dividend, attach it to 62 and continue: 623 / 77

Going ahead to step 3:
When dividing 623 by 77, we get 8 with a remainder of 7.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
The remainder is 7 after subtracting 616 from 623.
Fetch the next digit (7) from the dividend, attach it to 7 and continue: 77 / 77

Moving on to step 4:
If we divide 77 by 77, we get 1 and a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 81.0
Subtract 77 from 77 to get 0.
Include the next digit (6) from the dividend after 0, then repeat: 6 / 77

Step 5:
6 divided by 77 is 0 with a remainder of 6.
Put 0 as the next digit of the answer. 
Result so far: 810.0
Subtracting 0 from 6 leaves us with 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 77

Let's proceed to step 6:
If we divide 60 by 77, we get 0 and a remainder of 60.
Put 0 as the next digit of the answer. 
Result so far: 8100.0
If we subtract 0 from 60, we get 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Going ahead to step 7:
77 can be fit into 600 7 times, resulting in a remainder of 61.
Put 7 as the next digit of the answer. 
Result so far: 8100.7
The remainder is 61 after subtracting 539 from 600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

On to step 8:
77 can be fit into 610 7 times, resulting in a remainder of 71.
The next digit of our result is 7. 
Result so far: 8100.77
Deduct 539 from 610 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

The final result is 8100.77 with a remainder of 0.071.
