328917 divided by 7 
The aim is to understand the frequency of 7 in 328917.

Moving on to step 1:
3 divided by 7 is 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 7

Moving on to step 2:
7 goes into 32 4 times with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
If we take 28 away from 32, we end up with 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 7

On to step 3:
The number 7 fits into 48 6 times, leaving a remainder of 6.
The next digit of our result is 6. 
Result so far: 46.0
Subtract 42 from 48 to get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 7

Let's proceed to step 4:
If we divide 69 by 7, we get 9 and a remainder of 6.
Write down 9 as next digit of the result. 
Result so far: 469.0
The remainder is 6 after subtracting 63 from 69.
Grab the next digit (1) from the dividend, add it to 6, then carry on: 61 / 7

Advancing to step 5:
The number 7 fits into 61 8 times, leaving a remainder of 5.
Write down 8 as next digit of the result. 
Result so far: 4698.0
Subtracting 56 from 61 leaves us with 5.
Include the next digit (7) from the dividend after 5, then repeat: 57 / 7

On to step 6:
57 divided by 7 is 8 with a remainder of 1.
The number 8 becomes the next digit in our result. 
Result so far: 46988.0
Subtract 56 from 57 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.

Moving on to step 7:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 46988.1
Subtracting 7 from 10 leaves us 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.

Step 8:
7 goes into 30 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 46988.14
The remainder is 2 after subtracting 28 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 46988.142
The remainder is 6 after subtracting 14 from 20.
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 10:
7 goes into 60 8 times with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 46988.1428
If we subtract 56 from 60, we 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 11:
When dividing 40 by 7, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 46988.14285
If we subtract 35 from 40, we get 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 12:
50 divided by 7 is 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 46988.142857
Subtracting 49 from 50 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 13:
When dividing 10 by 7, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 46988.1428571
The remainder is 3 after subtracting 7 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 14:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 46988.14285714
The remainder is 2 after subtracting 28 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

In conclusion, the division gives 46988.14285714 with a balance of 2e-09.
