792005 ÷ 77 
The aim is to understand the frequency of 77 in 792005.

Let's proceed to step 1:
The number 77 fits into 7 0 times, leaving 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.
Fetch the next digit (9) from the dividend, attach it to 7 and continue: 79 / 77

Advancing to step 2:
77 can be fit into 79 1 times, resulting in a remainder of 2.
The next digit of our result is 1. 
Result so far: 1.0
If we take 77 away from 79, we end up with 2.
Grab the next digit (2) from the dividend, add it to 2, then carry on: 22 / 77

Let's proceed to step 3:
77 goes into 22 0 times with a remainder of 22.
The next digit of our result is 0. 
Result so far: 10.0
The remainder is 22 after subtracting 0 from 22.
Grab the next digit (0) from the dividend, add it to 22, then carry on: 220 / 77

Let's proceed to step 4:
77 goes into 220 2 times with a remainder of 66.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
If we subtract 154 from 220, we get 66.
Bring next digit (0) of the dividend behind the 66 and repeat the process: 660 / 77

Let's proceed to step 5:
77 can be fit into 660 8 times, resulting in a remainder of 44.
The next digit of our result is 8. 
Result so far: 1028.0
Deduct 616 from 660 and we're left with 44.
Bring next digit (5) of the dividend behind the 44 and repeat the process: 445 / 77

On to step 6:
77 goes into 445 5 times with a remainder of 60.
The next digit of our result is 5. 
Result so far: 10285.0
Subtracting 385 from 445 leaves us with 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 600, and continue the process.

Advancing to step 7:
If we divide 600 by 77, we get 7 and a remainder of 61.
Put 7 as the next digit of the answer. 
Result so far: 10285.7
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.

Moving on to step 8:
When dividing 610 by 77, we get 7 with a remainder of 71.
Record the quotient 7 as the next digit in the result. 
Result so far: 10285.77
Subtract 539 from 610 to get 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 quotient of the division is 10285.77, and the remainder is 0.071.
