We're dividing 456424 by 7 
The aim is to understand the frequency of 7 in 456424.

Moving on to step 1:
7 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 7

Let's proceed to step 2:
The number 7 fits into 45 6 times, leaving a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 6.0
If we take 42 away from 45, we end up with 3.
Grab the next digit (6) from the dividend, add it to 3, then carry on: 36 / 7

Going ahead to step 3:
7 can be fit into 36 5 times, resulting in a remainder of 1.
The next digit of our result is 5. 
Result so far: 65.0
Subtracting 35 from 36 leaves us with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 7

Step 4:
The number 7 fits into 14 2 times, leaving a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 652.0
If we take 14 away from 14, we end up with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 7

On to step 5:
7 goes into 2 0 times with a remainder of 2.
Put 0 as the next digit of the answer. 
Result so far: 6520.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 7

Step 6:
7 goes into 24 3 times with a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 65203.0
Subtracting 21 from 24 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.

On to step 7:
7 goes into 30 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 65203.4
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.

Going ahead to step 8:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 65203.42
If we subtract 14 from 20, we 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.

Going ahead to step 9:
If we divide 60 by 7, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 65203.428
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.

On to step 10:
When dividing 40 by 7, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 65203.4285
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.

Step 11:
The number 7 fits into 50 7 times, leaving a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 65203.42857
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 12:
7 goes into 10 1 times with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 65203.428571
Deduct 7 from 10 and we're left 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.

Let's proceed to step 13:
30 divided by 7 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 65203.4285714
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.

On to step 14:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 65203.42857142
If we subtract 14 from 20, we 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.

The final result is 65203.42857142 with a remainder of 6e-09.
