976878 ÷ 79 
The aim is to understand the frequency of 79 in 976878.

Step 1:
The number 79 fits into 9 0 times, leaving a remainder of 9.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 9, we end up with 9.
Grab the next digit (7) from the dividend, add it to 9, then carry on: 97 / 79

Advancing to step 2:
79 can be fit into 97 1 times, resulting in a remainder of 18.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtracting 79 from 97 leaves us with 18.
Append the next digit (6) from the dividend to 18 and continue with: 186 / 79

Let's proceed to step 3:
186 divided by 79 is 2 with a remainder of 28.
Put 2 as the next digit of the answer. 
Result so far: 12.0
The remainder is 28 after subtracting 158 from 186.
Bring next digit (8) of the dividend behind the 28 and repeat the process: 288 / 79

Moving on to step 4:
79 can be fit into 288 3 times, resulting in a remainder of 51.
Record the quotient 3 as the next digit in the result. 
Result so far: 123.0
Subtract 237 from 288 to get 51.
Include the next digit (7) from the dividend after 51, then repeat: 517 / 79

Advancing to step 5:
The number 79 fits into 517 6 times, leaving a remainder of 43.
The number 6 becomes the next digit in our result. 
Result so far: 1236.0
Subtracting 474 from 517 leaves us with 43.
Append the next digit (8) from the dividend to 43 and continue with: 438 / 79

Let's proceed to step 6:
79 can be fit into 438 5 times, resulting in a remainder of 43.
Use 5 as the next digit of our solution. 
Result so far: 12365.0
Subtract 395 from 438 to get 43.
Since there are no more digits in the dividend, we add a zero to the remainder making it 430, and continue the process.

Moving on to step 7:
79 can be fit into 430 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 12365.5
If we subtract 395 from 430, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 8:
When dividing 350 by 79, we get 4 with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 12365.54
Subtract 316 from 350 to get 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 9:
79 can be fit into 340 4 times, resulting in a remainder of 24.
Put 4 as the next digit of the answer. 
Result so far: 12365.544
If we take 316 away from 340, we end up 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.

The final outcome is 12365.544, with a leftover of 0.0024.
