713902 ÷ 7 
The aim is to understand the frequency of 7 in 713902.

Advancing to step 1:
7 divided by 7 is 1 with a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 0 after subtracting 7 from 7.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 7

Advancing to step 2:
When dividing 1 by 7, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 10.0
If we subtract 0 from 1, we get 1.
Take the next digit (3) from the dividend and append it to 1, then repeat: 13 / 7

Moving on to step 3:
13 divided by 7 is 1 with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 101.0
Subtract 7 from 13 to get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 7

Let's proceed to step 4:
When dividing 69 by 7, we get 9 with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 1019.0
Subtract 63 from 69 to get 6.
Fetch the next digit (0) from the dividend, attach it to 6 and continue: 60 / 7

On to step 5:
If we divide 60 by 7, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 10198.0
The remainder is 4 after subtracting 56 from 60.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 7

On to step 6:
When dividing 42 by 7, we get 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 101986.0
If we take 42 away from 42, we end up 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.

Let's proceed to step 7:
7 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 101986.0
Subtract 0 from 0 to 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 8:
The number 7 fits into 0 0 times, leaving a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 101986.0
Subtract 0 from 0 to 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.

After the division, we end up with 101986.0 and a remainder of 0.0.
