We look at the division of 449317 by 7 
The aim is to understand the frequency of 7 in 449317.

Advancing to step 1:
7 can be fit into 4 0 times, resulting in a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (4) from the dividend after 4, then repeat: 44 / 7

Moving on to step 2:
The number 7 fits into 44 6 times, leaving a remainder of 2.
The next digit of our result is 6. 
Result so far: 6.0
If we take 42 away from 44, we end up with 2.
Grab the next digit (9) from the dividend, add it to 2, then carry on: 29 / 7

Let's proceed to step 3:
When dividing 29 by 7, we get 4 with a remainder of 1.
The number 4 becomes the next digit in our result. 
Result so far: 64.0
The remainder is 1 after subtracting 28 from 29.
Fetch the next digit (3) from the dividend, attach it to 1 and continue: 13 / 7

On to step 4:
The number 7 fits into 13 1 times, leaving a remainder of 6.
Put 1 as the next digit of the answer. 
Result so far: 641.0
If we take 7 away from 13, we end up with 6.
Append the next digit (1) from the dividend to 6 and continue with: 61 / 7

Let's proceed to step 5:
61 divided by 7 is 8 with a remainder of 5.
The next digit of our result is 8. 
Result so far: 6418.0
If we subtract 56 from 61, we get 5.
Take the next digit (7) from the dividend and append it to 5, then repeat: 57 / 7

Moving on to step 6:
If we divide 57 by 7, we get 8 and a remainder of 1.
Record the quotient 8 as the next digit in the result. 
Result so far: 64188.0
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.

Step 7:
When dividing 10 by 7, we get 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 64188.1
Deduct 7 from 10 and we're left 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 can be fit into 30 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 64188.14
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.

Step 9:
7 goes into 20 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 64188.142
If we subtract 14 from 20, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Moving on to step 10:
The number 7 fits into 60 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 64188.1428
If we take 56 away from 60, we end up 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 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: 64188.14285
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.

Going ahead to step 12:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 64188.142857
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.

Advancing to step 13:
7 can be fit into 10 1 times, resulting in a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 64188.1428571
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.

Advancing to step 14:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 64188.14285714
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.

Our division results in 64188.14285714 with a remaining 2e-09.
