We look at the division of 20750968 by 7 
The aim is to understand the frequency of 7 in 20750968.

On to step 1:
If we divide 2 by 7, we get 0 and 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.
Include the next digit (0) from the dividend after 2, then repeat: 20 / 7

Advancing to step 2:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
If we take 14 away from 20, we end up with 6.
Take the next digit (7) from the dividend and append it to 6, then repeat: 67 / 7

Step 3:
7 goes into 67 9 times with a remainder of 4.
The next digit of our result is 9. 
Result so far: 29.0
Subtracting 63 from 67 leaves us with 4.
Append the next digit (5) from the dividend to 4 and continue with: 45 / 7

Moving on to step 4:
When dividing 45 by 7, we get 6 with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 296.0
Subtracting 42 from 45 leaves us with 3.
Bring next digit (0) of the dividend behind the 3 and repeat the process: 30 / 7

Let's proceed to step 5:
When dividing 30 by 7, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 2964.0
If we take 28 away from 30, we end up with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 7

Step 6:
29 divided by 7 is 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 29644.0
If we subtract 28 from 29, we get 1.
Include the next digit (6) from the dividend after 1, then repeat: 16 / 7

On to step 7:
7 can be fit into 16 2 times, resulting in a remainder of 2.
The number 2 becomes the next digit in our result. 
Result so far: 296442.0
Deduct 14 from 16 and we're left with 2.
Include the next digit (8) from the dividend after 2, then repeat: 28 / 7

Let's proceed to step 8:
The number 7 fits into 28 4 times, leaving a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 2964424.0
If we subtract 28 from 28, we get 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 9:
The number 7 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 2964424.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 10:
If we divide 0 by 7, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 2964424.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

In conclusion, the division gives 2964424.0 with a balance of 0.0.
