We're dividing 423379 by 79 
The aim is to understand the frequency of 79 in 423379.

Moving on to step 1:
79 goes into 4 0 times with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 4 and we're left with 4.
Grab the next digit (2) from the dividend, add it to 4, then carry on: 42 / 79

Let's proceed to step 2:
79 can be fit into 42 0 times, resulting in a remainder of 42.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Bring next digit (3) of the dividend behind the 42 and repeat the process: 423 / 79

Advancing to step 3:
The number 79 fits into 423 5 times, leaving a remainder of 28.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Subtracting 395 from 423 leaves us with 28.
Bring next digit (3) of the dividend behind the 28 and repeat the process: 283 / 79

Moving on to step 4:
79 goes into 283 3 times with a remainder of 46.
The next digit of our result is 3. 
Result so far: 53.0
Deduct 237 from 283 and we're left with 46.
Take the next digit (7) from the dividend and append it to 46, then repeat: 467 / 79

Step 5:
If we divide 467 by 79, we get 5 and a remainder of 72.
Use 5 as the next digit of our solution. 
Result so far: 535.0
Subtracting 395 from 467 leaves us with 72.
Include the next digit (9) from the dividend after 72, then repeat: 729 / 79

Let's proceed to step 6:
79 goes into 729 9 times with a remainder of 18.
The number 9 becomes the next digit in our result. 
Result so far: 5359.0
Deduct 711 from 729 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Advancing to step 7:
180 divided by 79 is 2 with a remainder of 22.
The number 2 becomes the next digit in our result. 
Result so far: 5359.2
The remainder is 22 after subtracting 158 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 220, and continue the process.

Moving on to step 8:
79 goes into 220 2 times with a remainder of 62.
Write down 2 as next digit of the result. 
Result so far: 5359.22
Deduct 158 from 220 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Our division results in 5359.22 with a remaining 0.062.
