518275 ÷ 77 
The aim is to understand the frequency of 77 in 518275.

Moving on to step 1:
77 can be fit into 5 0 times, resulting in a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 5, we get 5.
Include the next digit (1) from the dividend after 5, then repeat: 51 / 77

Step 2:
If we divide 51 by 77, we get 0 and a remainder of 51.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 51 leaves us with 51.
Take the next digit (8) from the dividend and append it to 51, then repeat: 518 / 77

Moving on to step 3:
If we divide 518 by 77, we get 6 and a remainder of 56.
Use 6 as the next digit of our solution. 
Result so far: 6.0
If we take 462 away from 518, we end up with 56.
Include the next digit (2) from the dividend after 56, then repeat: 562 / 77

Going ahead to step 4:
77 goes into 562 7 times with a remainder of 23.
Put 7 as the next digit of the answer. 
Result so far: 67.0
The remainder is 23 after subtracting 539 from 562.
Include the next digit (7) from the dividend after 23, then repeat: 237 / 77

Let's proceed to step 5:
When dividing 237 by 77, we get 3 with a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 673.0
If we subtract 231 from 237, we get 6.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 77

Let's proceed to step 6:
The number 77 fits into 65 0 times, leaving a remainder of 65.
Put 0 as the next digit of the answer. 
Result so far: 6730.0
If we subtract 0 from 65, we get 65.
Since there are no more digits in the dividend, we add a zero to the remainder making it 650, and continue the process.

Step 7:
77 goes into 650 8 times with a remainder of 34.
Use 8 as the next digit of our solution. 
Result so far: 6730.8
Subtracting 616 from 650 leaves us with 34.
Since there are no more digits in the dividend, we add a zero to the remainder making it 340, and continue the process.

On to step 8:
When dividing 340 by 77, we get 4 with a remainder of 32.
Use 4 as the next digit of our solution. 
Result so far: 6730.84
If we take 308 away from 340, we end up with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 9:
77 goes into 320 4 times with a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 6730.844
If we subtract 308 from 320, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Our division results in 6730.844 with a remaining 0.0012.
