We look at the division of 9306084 by 7 
The aim is to understand the frequency of 7 in 9306084.

Advancing to step 1:
7 can be fit into 9 1 times, resulting in a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 2 after subtracting 7 from 9.
Fetch the next digit (3) from the dividend, attach it to 2 and continue: 23 / 7

Going ahead to step 2:
The number 7 fits into 23 3 times, leaving a remainder of 2.
The next digit of our result is 3. 
Result so far: 13.0
Subtracting 21 from 23 leaves us with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 7

Going ahead to step 3:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 132.0
Subtract 14 from 20 to get 6.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 7

Let's proceed to step 4:
The number 7 fits into 66 9 times, leaving a remainder of 3.
Record the quotient 9 as the next digit in the result. 
Result so far: 1329.0
Subtract 63 from 66 to get 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 7

Advancing to step 5:
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: 13294.0
Subtracting 28 from 30 leaves us with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 7

Advancing to step 6:
7 can be fit into 28 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 132944.0
If we subtract 28 from 28, we get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 7

Going ahead to step 7:
7 goes into 4 0 times with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 1329440.0
Deduct 0 from 4 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 8:
When dividing 40 by 7, we get 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 1329440.5
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.

Let's proceed to step 9:
7 can be fit into 50 7 times, resulting in a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 1329440.57
The remainder is 1 after subtracting 49 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 10:
If we divide 10 by 7, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 1329440.571
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.

On to step 11:
When dividing 30 by 7, we get 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 1329440.5714
Subtract 28 from 30 to 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.

Moving on to step 12:
If we divide 20 by 7, we get 2 and a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 1329440.57142
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.

Advancing to step 13:
7 goes into 60 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 1329440.571428
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.

Step 14:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 1329440.5714285
Deduct 35 from 40 and we're left 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 15:
50 divided by 7 is 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 1329440.57142857
If we subtract 49 from 50, we 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.

The quotient of the division is 1329440.57142857, and the remainder is 1e-09.
