Let's divide 488431 by 7
The aim is to understand the frequency of 7 in 488431.

Advancing to step 1:
7 can be fit into 4 0 times, resulting in a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 7

Advancing to step 2:
The number 7 fits into 48 6 times, leaving a remainder of 6.
Put 6 as the next digit of the answer. 
Result so far: 6.0
Subtracting 42 from 48 leaves us with 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 7

On to step 3:
When dividing 68 by 7, we get 9 with a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 69.0
If we take 63 away from 68, we end up with 5.
Include the next digit (4) from the dividend after 5, then repeat: 54 / 7

Let's proceed to step 4:
When dividing 54 by 7, we get 7 with a remainder of 5.
Use 7 as the next digit of our solution. 
Result so far: 697.0
If we take 49 away from 54, we end up with 5.
Include the next digit (3) from the dividend after 5, then repeat: 53 / 7

Step 5:
7 can be fit into 53 7 times, resulting in a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 6977.0
If we take 49 away from 53, we end up with 4.
Include the next digit (1) from the dividend after 4, then repeat: 41 / 7

Going ahead to step 6:
7 goes into 41 5 times with a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 69775.0
The remainder is 6 after subtracting 35 from 41.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 7:
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: 69775.8
Deduct 56 from 60 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.

Step 8:
40 divided by 7 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 69775.85
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.

Moving on to step 9:
When dividing 50 by 7, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 69775.857
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.

Advancing to step 10:
If we divide 10 by 7, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 69775.8571
Subtract 7 from 10 to 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.

Advancing to step 11:
30 divided by 7 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 69775.85714
Deduct 28 from 30 and we're left 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.

Advancing to step 12:
7 goes into 20 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 69775.857142
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.

Advancing to step 13:
60 divided by 7 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 69775.8571428
The remainder is 4 after subtracting 56 from 60.
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 14:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 69775.85714285
The remainder is 5 after subtracting 35 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

In conclusion, the division gives 69775.85714285 with a balance of 5e-09.
