684432 divided by 7 
The aim is to understand the frequency of 7 in 684432.

Step 1:
If we divide 6 by 7, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 6 leaves us with 6.
Grab the next digit (8) from the dividend, add it to 6, then carry on: 68 / 7

On to step 2:
7 can be fit into 68 9 times, resulting in a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtracting 63 from 68 leaves us with 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 7

Moving on to step 3:
When dividing 54 by 7, we get 7 with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 97.0
Deduct 49 from 54 and we're left with 5.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 7

Going ahead to step 4:
7 can be fit into 54 7 times, resulting in a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 977.0
Deduct 49 from 54 and we're left with 5.
Grab the next digit (3) from the dividend, add it to 5, then carry on: 53 / 7

Advancing to step 5:
53 divided by 7 is 7 with a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 9777.0
The remainder is 4 after subtracting 49 from 53.
Take the next digit (2) from the dividend and append it to 4, then repeat: 42 / 7

Going ahead to step 6:
7 can be fit into 42 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 97776.0
Subtracting 42 from 42 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.

Moving on to step 7:
When dividing 0 by 7, we get 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 97776.0
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.

Step 8:
If we divide 0 by 7, we get 0 and a remainder of 0.
The next digit of our result is 0. 
Result so far: 97776.0
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.

In conclusion, the division gives 97776.0 with a balance of 0.0.
