222870 ÷ 7 
The aim is to understand the frequency of 7 in 222870.

Moving on to step 1:
7 can be fit into 2 0 times, resulting in a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Take the next digit (2) from the dividend and append it to 2, then repeat: 22 / 7

Advancing to step 2:
22 divided by 7 is 3 with a remainder of 1.
The number 3 becomes the next digit in our result. 
Result so far: 3.0
Subtracting 21 from 22 leaves us with 1.
Bring next digit (2) of the dividend behind the 1 and repeat the process: 12 / 7

Step 3:
If we divide 12 by 7, we get 1 and a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 31.0
If we subtract 7 from 12, we get 5.
Bring next digit (8) of the dividend behind the 5 and repeat the process: 58 / 7

Moving on to step 4:
The number 7 fits into 58 8 times, leaving a remainder of 2.
Put 8 as the next digit of the answer. 
Result so far: 318.0
Deduct 56 from 58 and we're left with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 7

Going ahead to step 5:
27 divided by 7 is 3 with a remainder of 6.
The next digit of our result is 3. 
Result so far: 3183.0
Subtracting 21 from 27 leaves us with 6.
Include the next digit (0) from the dividend after 6, then repeat: 60 / 7

Step 6:
60 divided by 7 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 31838.0
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.

Moving on to step 7:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 31838.5
If we subtract 35 from 40, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Moving on to step 8:
7 goes into 50 7 times with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 31838.57
Deduct 49 from 50 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.

Step 9:
10 divided by 7 is 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 31838.571
If we subtract 7 from 10, we get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Moving on to step 10:
30 divided by 7 is 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 31838.5714
The remainder is 2 after subtracting 28 from 30.
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 11:
If we divide 20 by 7, we get 2 and a remainder of 6.
The next digit of our result is 2. 
Result so far: 31838.57142
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.

Let's proceed to step 12:
The number 7 fits into 60 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 31838.571428
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.

On to step 13:
7 goes into 40 5 times with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 31838.5714285
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.

Moving on to step 14:
If we divide 50 by 7, we get 7 and a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 31838.57142857
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.

In conclusion, the division gives 31838.57142857 with a balance of 1e-09.
