We look at the division of 79313 by 7 
The aim is to understand the frequency of 7 in 79313.

Step 1:
7 divided by 7 is 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 0 after subtracting 7 from 7.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 7

Let's proceed to step 2:
When dividing 9 by 7, we get 1 with a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 11.0
Deduct 7 from 9 and we're left with 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 7

On to step 3:
If we divide 23 by 7, we get 3 and a remainder of 2.
The next digit of our result is 3. 
Result so far: 113.0
If we subtract 21 from 23, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 7

Advancing to step 4:
7 goes into 21 3 times with a remainder of 0.
The next digit of our result is 3. 
Result so far: 1133.0
The remainder is 0 after subtracting 21 from 21.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 7

On to step 5:
7 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 11330.0
If we subtract 0 from 3, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Let's proceed to step 6:
If we divide 30 by 7, we get 4 and a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 11330.4
Subtracting 28 from 30 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 7:
20 divided by 7 is 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 11330.42
Deduct 14 from 20 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 8:
If we divide 60 by 7, we get 8 and a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 11330.428
Subtract 56 from 60 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 9:
7 goes into 40 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 11330.4285
If we take 35 away from 40, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 10:
7 goes into 50 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 11330.42857
Subtract 49 from 50 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 11:
When dividing 10 by 7, we get 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 11330.428571
If we take 7 away from 10, we end up with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Advancing to step 12:
30 divided by 7 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 11330.4285714
If we subtract 28 from 30, we get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 13:
7 goes into 20 2 times with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 11330.42857142
Subtracting 14 from 20 leaves us with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

In conclusion, the division gives 11330.42857142 with a balance of 6e-09.
