726576 divided by 7 
The aim is to understand the frequency of 7 in 726576.

Going ahead to step 1:
The number 7 fits into 7 1 times, leaving a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 7 from 7 leaves us with 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 7

Advancing to step 2:
2 divided by 7 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 10.0
If we subtract 0 from 2, we get 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 7

Let's proceed to step 3:
26 divided by 7 is 3 with a remainder of 5.
Put 3 as the next digit of the answer. 
Result so far: 103.0
Deduct 21 from 26 and we're left with 5.
Include the next digit (5) from the dividend after 5, then repeat: 55 / 7

Moving on to step 4:
7 goes into 55 7 times with a remainder of 6.
Record the quotient 7 as the next digit in the result. 
Result so far: 1037.0
Subtract 49 from 55 to get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 7

Step 5:
7 can be fit into 67 9 times, resulting in a remainder of 4.
The next digit of our result is 9. 
Result so far: 10379.0
Subtracting 63 from 67 leaves us with 4.
Include the next digit (6) from the dividend after 4, then repeat: 46 / 7

Step 6:
46 divided by 7 is 6 with a remainder of 4.
The next digit of our result is 6. 
Result so far: 103796.0
If we take 42 away from 46, 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 7:
7 goes into 40 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 103796.5
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.

On to step 8:
50 divided by 7 is 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 103796.57
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.

Step 9:
7 can be fit into 10 1 times, resulting in a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 103796.571
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.

Advancing to step 10:
7 goes into 30 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 103796.5714
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.

Moving on to step 11:
When dividing 20 by 7, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 103796.57142
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.

Let's proceed to step 12:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 103796.571428
If we take 56 away from 60, 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.

Let's proceed to step 13:
7 goes into 40 5 times with a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 103796.5714285
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 14:
50 divided by 7 is 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 103796.57142857
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.

After the division, we end up with 103796.57142857 and a remainder of 1e-09.
