We look at the division of 936420 by 79 
The aim is to understand the frequency of 79 in 936420.

Advancing to step 1:
9 divided by 79 is 0 with a remainder of 9.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 9 to get 9.
Append the next digit (3) from the dividend to 9 and continue with: 93 / 79

Let's proceed to step 2:
79 can be fit into 93 1 times, resulting in a remainder of 14.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtract 79 from 93 to get 14.
Grab the next digit (6) from the dividend, add it to 14, then carry on: 146 / 79

Going ahead to step 3:
146 divided by 79 is 1 with a remainder of 67.
Put 1 as the next digit of the answer. 
Result so far: 11.0
Deduct 79 from 146 and we're left with 67.
Append the next digit (4) from the dividend to 67 and continue with: 674 / 79

Moving on to step 4:
674 divided by 79 is 8 with a remainder of 42.
The next digit of our result is 8. 
Result so far: 118.0
The remainder is 42 after subtracting 632 from 674.
Include the next digit (2) from the dividend after 42, then repeat: 422 / 79

Going ahead to step 5:
422 divided by 79 is 5 with a remainder of 27.
The number 5 becomes the next digit in our result. 
Result so far: 1185.0
Subtract 395 from 422 to get 27.
Append the next digit (0) from the dividend to 27 and continue with: 270 / 79

Step 6:
When dividing 270 by 79, we get 3 with a remainder of 33.
Put 3 as the next digit of the answer. 
Result so far: 11853.0
The remainder is 33 after subtracting 237 from 270.
Since there are no more digits in the dividend, we add a zero to the remainder making it 330, and continue the process.

Moving on to step 7:
330 divided by 79 is 4 with a remainder of 14.
Use 4 as the next digit of our solution. 
Result so far: 11853.4
If we subtract 316 from 330, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Going ahead to step 8:
The number 79 fits into 140 1 times, leaving a remainder of 61.
Record the quotient 1 as the next digit in the result. 
Result so far: 11853.41
Subtracting 79 from 140 leaves us with 61.
Since there are no more digits in the dividend, we add a zero to the remainder making it 610, and continue the process.

Let's proceed to step 9:
If we divide 610 by 79, we get 7 and a remainder of 57.
The number 7 becomes the next digit in our result. 
Result so far: 11853.417
Deduct 553 from 610 and we're left with 57.
Since there are no more digits in the dividend, we add a zero to the remainder making it 570, and continue the process.

Moving on to step 10:
If we divide 570 by 79, we get 7 and a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 11853.4177
Subtract 553 from 570 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

In conclusion, the division gives 11853.4177 with a balance of 0.00017.
