We're dividing 828466 by 79 
The aim is to understand the frequency of 79 in 828466.

On to step 1:
The number 79 fits into 8 0 times, leaving a remainder of 8.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 8, we end up with 8.
Append the next digit (2) from the dividend to 8 and continue with: 82 / 79

Going ahead to step 2:
79 can be fit into 82 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 79 from 82, we get 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 79

Going ahead to step 3:
79 can be fit into 38 0 times, resulting in a remainder of 38.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 38, we get 38.
Fetch the next digit (4) from the dividend, attach it to 38 and continue: 384 / 79

Going ahead to step 4:
79 goes into 384 4 times with a remainder of 68.
Record the quotient 4 as the next digit in the result. 
Result so far: 104.0
Deduct 316 from 384 and we're left with 68.
Take the next digit (6) from the dividend and append it to 68, then repeat: 686 / 79

On to step 5:
79 goes into 686 8 times with a remainder of 54.
Record the quotient 8 as the next digit in the result. 
Result so far: 1048.0
Subtracting 632 from 686 leaves us with 54.
Include the next digit (6) from the dividend after 54, then repeat: 546 / 79

Going ahead to step 6:
When dividing 546 by 79, we get 6 with a remainder of 72.
Put 6 as the next digit of the answer. 
Result so far: 10486.0
If we take 474 away from 546, we end up 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.

Let's proceed to step 7:
The number 79 fits into 720 9 times, leaving a remainder of 9.
Write down 9 as next digit of the result. 
Result so far: 10486.9
If we take 711 away from 720, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Advancing to step 8:
79 goes into 90 1 times with a remainder of 11.
Write down 1 as next digit of the result. 
Result so far: 10486.91
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.

Moving on to step 9:
If we divide 110 by 79, we get 1 and a remainder of 31.
Record the quotient 1 as the next digit in the result. 
Result so far: 10486.911
If we subtract 79 from 110, we get 31.
Since there are no more digits in the dividend, we add a zero to the remainder making it 310, and continue the process.

After the division, we end up with 10486.911 and a remainder of 0.0031.
