Let's divide 223315 by 7
The aim is to understand the frequency of 7 in 223315.

Advancing to step 1:
7 can be fit into 2 0 times, resulting in a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 7

Moving on to step 2:
22 divided by 7 is 3 with a remainder of 1.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 1 after subtracting 21 from 22.
Append the next digit (3) from the dividend to 1 and continue with: 13 / 7

Step 3:
If we divide 13 by 7, we get 1 and a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 31.0
Subtract 7 from 13 to get 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 7

Step 4:
The number 7 fits into 63 9 times, leaving a remainder of 0.
Use 9 as the next digit of our solution. 
Result so far: 319.0
The remainder is 0 after subtracting 63 from 63.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 7

Let's proceed to step 5:
When dividing 1 by 7, we get 0 with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 3190.0
Subtracting 0 from 1 leaves us with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 7

Let's proceed to step 6:
The number 7 fits into 15 2 times, leaving a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 31902.0
If we take 14 away from 15, 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.

Advancing to step 7:
The number 7 fits into 10 1 times, leaving a remainder of 3.
The next digit of our result is 1. 
Result so far: 31902.1
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.

Let's proceed to step 8:
When dividing 30 by 7, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 31902.14
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.

Going ahead to step 9:
7 goes into 20 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 31902.142
If we take 14 away from 20, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 10:
60 divided by 7 is 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 31902.1428
If we take 56 away from 60, we end up with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
7 goes into 40 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 31902.14285
Subtracting 35 from 40 leaves us 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.

Step 12:
If we divide 50 by 7, we get 7 and a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 31902.142857
The remainder is 1 after subtracting 49 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Going ahead to step 13:
10 divided by 7 is 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 31902.1428571
Subtracting 7 from 10 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 14:
If we divide 30 by 7, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 31902.14285714
Subtracting 28 from 30 leaves us 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.

Our division results in 31902.14285714 with a remaining 2e-09.
