We look at the division of 809506 by 79 
The aim is to understand the frequency of 79 in 809506.

Advancing to step 1:
79 can be fit into 8 0 times, resulting in a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 8, we get 8.
Grab the next digit (0) from the dividend, add it to 8, then carry on: 80 / 79

Going ahead to step 2:
If we divide 80 by 79, we get 1 and a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
If we subtract 79 from 80, we get 1.
Take the next digit (9) from the dividend and append it to 1, then repeat: 19 / 79

Moving on to step 3:
79 goes into 19 0 times with a remainder of 19.
Write down 0 as next digit of the result. 
Result so far: 10.0
If we take 0 away from 19, we end up with 19.
Grab the next digit (5) from the dividend, add it to 19, then carry on: 195 / 79

Moving on to step 4:
79 goes into 195 2 times with a remainder of 37.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
If we take 158 away from 195, we end up with 37.
Include the next digit (0) from the dividend after 37, then repeat: 370 / 79

On to step 5:
79 goes into 370 4 times with a remainder of 54.
The number 4 becomes the next digit in our result. 
Result so far: 1024.0
The remainder is 54 after subtracting 316 from 370.
Fetch the next digit (6) from the dividend, attach it to 54 and continue: 546 / 79

Let's proceed to step 6:
The number 79 fits into 546 6 times, leaving a remainder of 72.
Record the quotient 6 as the next digit in the result. 
Result so far: 10246.0
Deduct 474 from 546 and we're left with 72.
Since there are no more digits in the dividend, we add a zero to the remainder making it 720, and continue the process.

On to step 7:
720 divided by 79 is 9 with a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 10246.9
The remainder is 9 after subtracting 711 from 720.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 8:
If we divide 90 by 79, we get 1 and a remainder of 11.
Record the quotient 1 as the next digit in the result. 
Result so far: 10246.91
Subtract 79 from 90 to get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 9:
79 can be fit into 110 1 times, resulting in a remainder of 31.
The number 1 becomes the next digit in our result. 
Result so far: 10246.911
Deduct 79 from 110 and we're left with 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

The final result is 10246.911 with a remainder of 0.0031.
