Let's divide 679702 by 7
The aim is to understand the frequency of 7 in 679702.

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
Subtracting 0 from 6 leaves us with 6.
Append the next digit (7) from the dividend to 6 and continue with: 67 / 7

On to step 2:
If we divide 67 by 7, we get 9 and a remainder of 4.
Record the quotient 9 as the next digit in the result. 
Result so far: 9.0
Subtracting 63 from 67 leaves us with 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 7

Advancing to step 3:
The number 7 fits into 49 7 times, leaving a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 97.0
If we subtract 49 from 49, we get 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 7

Step 4:
When dividing 7 by 7, we get 1 with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 971.0
Subtract 7 from 7 to get 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 7

Moving on to step 5:
0 divided by 7 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 9710.0
Subtracting 0 from 0 leaves us with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 7

Advancing to step 6:
The number 7 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 97100.0
Subtracting 0 from 2 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.

Moving on to step 7:
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: 97100.2
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.

Advancing to step 8:
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: 97100.28
If we subtract 56 from 60, we 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.

Let's proceed to step 9:
7 can be fit into 40 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 97100.285
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 10:
7 can be fit into 50 7 times, resulting in a remainder of 1.
The next digit of our result is 7. 
Result so far: 97100.2857
If we subtract 49 from 50, we 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.

On to step 11:
10 divided by 7 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 97100.28571
If we take 7 away from 10, 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.

Going ahead to step 12:
When dividing 30 by 7, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 97100.285714
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 13:
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: 97100.2857142
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 14:
60 divided by 7 is 8 with a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 97100.28571428
Subtracting 56 from 60 leaves us 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.

The quotient of the division is 97100.28571428, and the remainder is 4e-09.
