We look at the division of 332273 by 7 
The aim is to understand the frequency of 7 in 332273.

Advancing to step 1:
7 can be fit into 3 0 times, resulting in a remainder of 3.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Grab the next digit (3) from the dividend, add it to 3, then carry on: 33 / 7

Step 2:
When dividing 33 by 7, we get 4 with a remainder of 5.
The next digit of our result is 4. 
Result so far: 4.0
If we take 28 away from 33, we end up with 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 7

Step 3:
When dividing 52 by 7, we get 7 with a remainder of 3.
The next digit of our result is 7. 
Result so far: 47.0
Deduct 49 from 52 and we're left with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 7

Let's proceed to step 4:
When dividing 32 by 7, we get 4 with a remainder of 4.
The number 4 becomes the next digit in our result. 
Result so far: 474.0
If we subtract 28 from 32, we get 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 7

On to step 5:
If we divide 47 by 7, we get 6 and a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 4746.0
Subtracting 42 from 47 leaves us with 5.
Take the next digit (3) from the dividend and append it to 5, then repeat: 53 / 7

On to step 6:
If we divide 53 by 7, we get 7 and a remainder of 4.
Write down 7 as next digit of the result. 
Result so far: 47467.0
If we subtract 49 from 53, we get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Advancing to step 7:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 47467.5
If we take 35 away from 40, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 8:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 47467.57
Subtracting 49 from 50 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 9:
If we divide 10 by 7, we get 1 and a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 47467.571
The remainder is 3 after subtracting 7 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 10:
When dividing 30 by 7, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 47467.5714
If we take 28 away from 30, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 11:
7 goes into 20 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 47467.57142
Subtract 14 from 20 to get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 12:
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: 47467.571428
Subtract 56 from 60 to get 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 13:
7 can be fit into 40 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 47467.5714285
The remainder is 5 after subtracting 35 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 14:
The number 7 fits into 50 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 47467.57142857
If we take 49 away from 50, we end up with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

The quotient of the division is 47467.57142857, and the remainder is 1e-09.
