115260 ÷ 77 
The aim is to understand the frequency of 77 in 115260.

Moving on to step 1:
When dividing 1 by 77, we get 0 with a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 1, we get 1.
Include the next digit (1) from the dividend after 1, then repeat: 11 / 77

Going ahead to step 2:
When dividing 11 by 77, we get 0 with a remainder of 11.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 11 and we're left with 11.
Grab the next digit (5) from the dividend, add it to 11, then carry on: 115 / 77

Advancing to step 3:
77 can be fit into 115 1 times, resulting in a remainder of 38.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
The remainder is 38 after subtracting 77 from 115.
Append the next digit (2) from the dividend to 38 and continue with: 382 / 77

On to step 4:
The number 77 fits into 382 4 times, leaving a remainder of 74.
Use 4 as the next digit of our solution. 
Result so far: 14.0
The remainder is 74 after subtracting 308 from 382.
Take the next digit (6) from the dividend and append it to 74, then repeat: 746 / 77

On to step 5:
77 goes into 746 9 times with a remainder of 53.
Record the quotient 9 as the next digit in the result. 
Result so far: 149.0
The remainder is 53 after subtracting 693 from 746.
Append the next digit (0) from the dividend to 53 and continue with: 530 / 77

Step 6:
When dividing 530 by 77, we get 6 with a remainder of 68.
The number 6 becomes the next digit in our result. 
Result so far: 1496.0
If we subtract 462 from 530, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Moving on to step 7:
If we divide 680 by 77, we get 8 and a remainder of 64.
Record the quotient 8 as the next digit in the result. 
Result so far: 1496.8
Subtract 616 from 680 to get 64.
Since there are no more digits in the dividend, we add a zero to the remainder making it 640, and continue the process.

On to step 8:
77 can be fit into 640 8 times, resulting in a remainder of 24.
Record the quotient 8 as the next digit in the result. 
Result so far: 1496.88
Subtracting 616 from 640 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

After the division, we end up with 1496.88 and a remainder of 0.024.
