Let's divide 66796 by 7
The aim is to understand the frequency of 7 in 66796.

Let's proceed to step 1:
If we divide 6 by 7, we get 0 and a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Append the next digit (6) from the dividend to 6 and continue with: 66 / 7

On to step 2:
If we divide 66 by 7, we get 9 and a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 9.0
Subtract 63 from 66 to get 3.
Bring next digit (7) of the dividend behind the 3 and repeat the process: 37 / 7

On to step 3:
7 can be fit into 37 5 times, resulting in a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 95.0
If we take 35 away from 37, we end up with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 7

On to step 4:
7 goes into 29 4 times with a remainder of 1.
Record the quotient 4 as the next digit in the result. 
Result so far: 954.0
If we take 28 away from 29, we end up with 1.
Bring next digit (6) of the dividend behind the 1 and repeat the process: 16 / 7

Let's proceed to step 5:
16 divided by 7 is 2 with a remainder of 2.
Write down 2 as next digit of the result. 
Result so far: 9542.0
The remainder is 2 after subtracting 14 from 16.
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 6:
7 goes into 20 2 times with a remainder of 6.
The next digit of our result is 2. 
Result so far: 9542.2
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.

Moving on to step 7:
When dividing 60 by 7, we get 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 9542.28
Subtract 56 from 60 to 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.

Going ahead to step 8:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 9542.285
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.

Step 9:
7 goes into 50 7 times with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 9542.2857
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.

On to step 10:
10 divided by 7 is 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 9542.28571
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.

Step 11:
When dividing 30 by 7, we get 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 9542.285714
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 12:
If we divide 20 by 7, we get 2 and a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 9542.2857142
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.

Going ahead to step 13:
When dividing 60 by 7, we get 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 9542.28571428
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.

After the division, we end up with 9542.28571428 and a remainder of 4e-09.
