We look at the division of 204844 by 7 
The aim is to understand the frequency of 7 in 204844.

On to step 1:
When dividing 2 by 7, we get 0 with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 7

Moving on to step 2:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 14 away from 20, we end up with 6.
Take the next digit (4) from the dividend and append it to 6, then repeat: 64 / 7

Step 3:
64 divided by 7 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 29.0
The remainder is 1 after subtracting 63 from 64.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 7

Moving on to step 4:
18 divided by 7 is 2 with a remainder of 4.
Write down 2 as next digit of the result. 
Result so far: 292.0
Subtract 14 from 18 to get 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 7

On to step 5:
44 divided by 7 is 6 with a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 2926.0
Deduct 42 from 44 and we're left with 2.
Bring next digit (4) of the dividend behind the 2 and repeat the process: 24 / 7

Going ahead to step 6:
If we divide 24 by 7, we get 3 and a remainder of 3.
The next digit of our result is 3. 
Result so far: 29263.0
If we take 21 away from 24, 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.

Moving on to step 7:
The number 7 fits into 30 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 29263.4
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.

On to step 8:
20 divided by 7 is 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 29263.42
If we take 14 away from 20, we end up 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 9:
If we divide 60 by 7, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 29263.428
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 10:
If we divide 40 by 7, we get 5 and a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 29263.4285
Subtracting 35 from 40 leaves us 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.

Advancing to step 11:
When dividing 50 by 7, we get 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 29263.42857
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 12:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 29263.428571
If we subtract 7 from 10, 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.

Going ahead to step 13:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 29263.4285714
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.

Let's proceed to step 14:
If we divide 20 by 7, we get 2 and a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 29263.42857142
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.

Our division results in 29263.42857142 with a remaining 6e-09.
