173079 ÷ 77 
The aim is to understand the frequency of 77 in 173079.

Step 1:
77 can be fit into 1 0 times, resulting in a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (7) of the dividend behind the 1 and repeat the process: 17 / 77

Let's proceed to step 2:
17 divided by 77 is 0 with a remainder of 17.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 17 to get 17.
Grab the next digit (3) from the dividend, add it to 17, then carry on: 173 / 77

Advancing to step 3:
77 goes into 173 2 times with a remainder of 19.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we subtract 154 from 173, we get 19.
Take the next digit (0) from the dividend and append it to 19, then repeat: 190 / 77

Advancing to step 4:
When dividing 190 by 77, we get 2 with a remainder of 36.
Put 2 as the next digit of the answer. 
Result so far: 22.0
If we subtract 154 from 190, we get 36.
Grab the next digit (7) from the dividend, add it to 36, then carry on: 367 / 77

Advancing to step 5:
When dividing 367 by 77, we get 4 with a remainder of 59.
Use 4 as the next digit of our solution. 
Result so far: 224.0
Subtract 308 from 367 to get 59.
Bring next digit (9) of the dividend behind the 59 and repeat the process: 599 / 77

Let's proceed to step 6:
599 divided by 77 is 7 with a remainder of 60.
The next digit of our result is 7. 
Result so far: 2247.0
Subtracting 539 from 599 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.

Step 7:
600 divided by 77 is 7 with a remainder of 61.
Record the quotient 7 as the next digit in the result. 
Result so far: 2247.7
Subtract 539 from 600 to get 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 8:
77 can be fit into 610 7 times, resulting in a remainder of 71.
Put 7 as the next digit of the answer. 
Result so far: 2247.77
The remainder is 71 after subtracting 539 from 610.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

After the division, we end up with 2247.77 and a remainder of 0.071.
