231323 ÷ 7 
The aim is to understand the frequency of 7 in 231323.

Advancing to step 1:
The number 7 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Take the next digit (3) from the dividend and append it to 2, then repeat: 23 / 7

Moving on to step 2:
7 can be fit into 23 3 times, resulting in a remainder of 2.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
If we take 21 away from 23, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 7

Let's proceed to step 3:
7 can be fit into 21 3 times, resulting in a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 33.0
If we take 21 away from 21, we end up with 0.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 7

Advancing to step 4:
3 divided by 7 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 330.0
If we take 0 away from 3, we end up with 3.
Bring next digit (2) of the dividend behind the 3 and repeat the process: 32 / 7

Going ahead to step 5:
7 goes into 32 4 times with a remainder of 4.
Record the quotient 4 as the next digit in the result. 
Result so far: 3304.0
If we take 28 away from 32, we end up with 4.
Append the next digit (3) from the dividend to 4 and continue with: 43 / 7

Let's proceed to step 6:
If we divide 43 by 7, we get 6 and a remainder of 1.
Record the quotient 6 as the next digit in the result. 
Result so far: 33046.0
Deduct 42 from 43 and we're left 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 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: 33046.1
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:
7 goes into 30 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 33046.14
Subtract 28 from 30 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
7 can be fit into 20 2 times, resulting in a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 33046.142
The remainder is 6 after subtracting 14 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 10:
7 goes into 60 8 times with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 33046.1428
The remainder is 4 after subtracting 56 from 60.
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:
If we divide 40 by 7, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 33046.14285
Deduct 35 from 40 and we're left 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.

Let's proceed to step 12:
50 divided by 7 is 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 33046.142857
Subtract 49 from 50 to get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Step 13:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 33046.1428571
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.

Step 14:
If we divide 30 by 7, we get 4 and a remainder of 2.
The next digit of our result is 4. 
Result so far: 33046.14285714
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.

The final outcome is 33046.14285714, with a leftover of 2e-09.
