We divide 685923 by 7
The aim is to understand the frequency of 7 in 685923.

Step 1:
7 goes into 6 0 times with a remainder of 6.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 6 after subtracting 0 from 6.
Fetch the next digit (8) from the dividend, attach it to 6 and continue: 68 / 7

Moving on to step 2:
If we divide 68 by 7, we get 9 and a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 9.0
If we take 63 away from 68, we end up with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 7

Step 3:
7 can be fit into 55 7 times, resulting in a remainder of 6.
Write down 7 as next digit of the result. 
Result so far: 97.0
Deduct 49 from 55 and we're left with 6.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 7

Going ahead to step 4:
7 goes into 69 9 times with a remainder of 6.
Use 9 as the next digit of our solution. 
Result so far: 979.0
If we subtract 63 from 69, we get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 7

Advancing to step 5:
When dividing 62 by 7, we get 8 with a remainder of 6.
Record the quotient 8 as the next digit in the result. 
Result so far: 9798.0
If we take 56 away from 62, we end up with 6.
Fetch the next digit (3) from the dividend, attach it to 6 and continue: 63 / 7

Step 6:
7 can be fit into 63 9 times, resulting in a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 97989.0
If we subtract 63 from 63, 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.

Let's proceed to step 7:
The number 7 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 97989.0
If we subtract 0 from 0, 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.

Going ahead to step 8:
When dividing 0 by 7, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 97989.0
Deduct 0 from 0 and we're left 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.

The final outcome is 97989.0, with a leftover of 0.0.
