We're dividing 403646 by 79 
The aim is to understand the frequency of 79 in 403646.

Step 1:
The number 79 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Bring next digit (0) of the dividend behind the 4 and repeat the process: 40 / 79

Advancing to step 2:
If we divide 40 by 79, we get 0 and a remainder of 40.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 40 leaves us with 40.
Fetch the next digit (3) from the dividend, attach it to 40 and continue: 403 / 79

On to step 3:
79 goes into 403 5 times with a remainder of 8.
Write down 5 as next digit of the result. 
Result so far: 5.0
If we subtract 395 from 403, we get 8.
Append the next digit (6) from the dividend to 8 and continue with: 86 / 79

On to step 4:
79 can be fit into 86 1 times, resulting in a remainder of 7.
Put 1 as the next digit of the answer. 
Result so far: 51.0
Subtract 79 from 86 to get 7.
Bring next digit (4) of the dividend behind the 7 and repeat the process: 74 / 79

Let's proceed to step 5:
79 goes into 74 0 times with a remainder of 74.
Use 0 as the next digit of our solution. 
Result so far: 510.0
Deduct 0 from 74 and we're left with 74.
Include the next digit (6) from the dividend after 74, then repeat: 746 / 79

Going ahead to step 6:
The number 79 fits into 746 9 times, leaving a remainder of 35.
Put 9 as the next digit of the answer. 
Result so far: 5109.0
Deduct 711 from 746 and we're left with 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 7:
79 goes into 350 4 times with a remainder of 34.
Put 4 as the next digit of the answer. 
Result so far: 5109.4
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.

Step 8:
340 divided by 79 is 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 5109.44
Subtracting 316 from 340 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.

In conclusion, the division gives 5109.44 with a balance of 0.024.
