823340 divided by 7 
The aim is to understand the frequency of 7 in 823340.

On to step 1:
7 can be fit into 8 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
Subtracting 7 from 8 leaves us with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 7

Step 2:
When dividing 12 by 7, we get 1 with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 11.0
Deduct 7 from 12 and we're left with 5.
Fetch the next digit (3) from the dividend, attach it to 5 and continue: 53 / 7

Advancing to step 3:
7 can be fit into 53 7 times, resulting in a remainder of 4.
Put 7 as the next digit of the answer. 
Result so far: 117.0
If we take 49 away from 53, we end up with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 7

Step 4:
The number 7 fits into 43 6 times, leaving a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 1176.0
Deduct 42 from 43 and we're left with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 7

On to step 5:
7 can be fit into 14 2 times, resulting in a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 11762.0
Subtracting 14 from 14 leaves us with 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 7

Moving on to step 6:
If we divide 0 by 7, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 117620.0
The remainder is 0 after subtracting 0 from 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:
0 divided by 7 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 117620.0
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.

On to step 8:
The number 7 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 117620.0
If we take 0 away from 0, 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.

The final outcome is 117620.0, with a leftover of 0.0.
