We look at the division of 152208 by 7 
The aim is to understand the frequency of 7 in 152208.

Step 1:
7 can be fit into 1 0 times, resulting in a remainder of 1.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 1 leaves us with 1.
Append the next digit (5) from the dividend to 1 and continue with: 15 / 7

Let's proceed to step 2:
If we divide 15 by 7, we get 2 and a remainder of 1.
Put 2 as the next digit of the answer. 
Result so far: 2.0
Subtracting 14 from 15 leaves us with 1.
Fetch the next digit (2) from the dividend, attach it to 1 and continue: 12 / 7

Moving on to step 3:
The number 7 fits into 12 1 times, leaving a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 21.0
If we take 7 away from 12, we end up with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 7

On to step 4:
If we divide 52 by 7, we get 7 and a remainder of 3.
The next digit of our result is 7. 
Result so far: 217.0
If we take 49 away from 52, we end up with 3.
Take the next digit (0) from the dividend and append it to 3, then repeat: 30 / 7

On to step 5:
7 goes into 30 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 2174.0
Subtract 28 from 30 to get 2.
Append the next digit (8) from the dividend to 2 and continue with: 28 / 7

Moving on to step 6:
7 can be fit into 28 4 times, resulting in a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 21744.0
The remainder is 0 after subtracting 28 from 28.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
When dividing 0 by 7, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 21744.0
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.

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: 21744.0
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 21744.0, with a leftover of 0.0.
