438814 divided by 7 
The aim is to understand the frequency of 7 in 438814.

Let's proceed to step 1:
The number 7 fits into 4 0 times, leaving a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (3) from the dividend and append it to 4, then repeat: 43 / 7

Going ahead to step 2:
7 goes into 43 6 times with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 6.0
Deduct 42 from 43 and we're left with 1.
Include the next digit (8) from the dividend after 1, then repeat: 18 / 7

Going ahead to step 3:
7 can be fit into 18 2 times, resulting in a remainder of 4.
The next digit of our result is 2. 
Result so far: 62.0
If we take 14 away from 18, we end up with 4.
Grab the next digit (8) from the dividend, add it to 4, then carry on: 48 / 7

Advancing to step 4:
If we divide 48 by 7, we get 6 and a remainder of 6.
Record the quotient 6 as the next digit in the result. 
Result so far: 626.0
If we subtract 42 from 48, we get 6.
Bring next digit (1) of the dividend behind the 6 and repeat the process: 61 / 7

Advancing to step 5:
When dividing 61 by 7, we get 8 with a remainder of 5.
Record the quotient 8 as the next digit in the result. 
Result so far: 6268.0
The remainder is 5 after subtracting 56 from 61.
Bring next digit (4) of the dividend behind the 5 and repeat the process: 54 / 7

Moving on to step 6:
If we divide 54 by 7, we get 7 and a remainder of 5.
Write down 7 as next digit of the result. 
Result so far: 62687.0
The remainder is 5 after subtracting 49 from 54.
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 7:
If we divide 50 by 7, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 62687.7
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.

Going ahead to step 8:
If we divide 10 by 7, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 62687.71
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 9:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 62687.714
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.

Step 10:
If we divide 20 by 7, we get 2 and a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 62687.7142
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.

On to step 11:
7 goes into 60 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 62687.71428
Subtracting 56 from 60 leaves us 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.

Advancing to step 12:
40 divided by 7 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 62687.714285
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 13:
50 divided by 7 is 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 62687.7142857
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 14:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 62687.71428571
Subtract 7 from 10 to 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.

In conclusion, the division gives 62687.71428571 with a balance of 3e-09.
