Let's divide 84560424 by 7
The aim is to understand the frequency of 7 in 84560424.

Advancing to step 1:
7 can be fit into 8 1 times, resulting in a remainder of 1.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 1 after subtracting 7 from 8.
Fetch the next digit (4) from the dividend, attach it to 1 and continue: 14 / 7

Step 2:
7 can be fit into 14 2 times, resulting in a remainder of 0.
The next digit of our result is 2. 
Result so far: 12.0
Deduct 14 from 14 and we're left with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 7

Step 3:
When dividing 5 by 7, we get 0 with a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 120.0
If we subtract 0 from 5, we get 5.
Grab the next digit (6) from the dividend, add it to 5, then carry on: 56 / 7

Going ahead to step 4:
7 goes into 56 8 times with a remainder of 0.
Write down 8 as next digit of the result. 
Result so far: 1208.0
Subtract 56 from 56 to get 0.
Include the next digit (0) from the dividend after 0, then repeat: 0 / 7

Let's proceed to step 5:
The number 7 fits into 0 0 times, leaving a remainder of 0.
The next digit of our result is 0. 
Result so far: 12080.0
If we take 0 away from 0, we end up with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 7

Advancing to step 6:
The number 7 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 120800.0
If we subtract 0 from 4, we get 4.
Append the next digit (2) from the dividend to 4 and continue with: 42 / 7

Advancing to step 7:
7 can be fit into 42 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 1208006.0
If we take 42 away from 42, we end up with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 7

On to step 8:
The number 7 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 12080060.0
If we take 0 away from 4, 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.

Step 9:
When dividing 40 by 7, we get 5 with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 12080060.5
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.

Going ahead to step 10:
50 divided by 7 is 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 12080060.57
If we subtract 49 from 50, we 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.

Going ahead to step 11:
When dividing 10 by 7, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 12080060.571
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.

On to step 12:
7 goes into 30 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 12080060.5714
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.

Let's proceed to step 13:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 12080060.57142
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.

Moving on to step 14:
If we divide 60 by 7, we get 8 and a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 12080060.571428
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.

On to step 15:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 12080060.5714285
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.

Step 16:
7 goes into 50 7 times with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 12080060.57142857
If we subtract 49 from 50, we 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.

After the division, we end up with 12080060.57142857 and a remainder of 1e-09.
