Let's divide 727576 by 7
The aim is to understand the frequency of 7 in 727576.

Advancing to step 1:
7 goes into 7 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
If we subtract 7 from 7, we get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 7

Moving on to step 2:
When dividing 2 by 7, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
If we subtract 0 from 2, we get 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 7

Let's proceed to step 3:
27 divided by 7 is 3 with a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 103.0
The remainder is 6 after subtracting 21 from 27.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 7

Moving on to step 4:
7 goes into 65 9 times with a remainder of 2.
The number 9 becomes the next digit in our result. 
Result so far: 1039.0
Deduct 63 from 65 and we're left with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 7

Step 5:
If we divide 27 by 7, we get 3 and a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 10393.0
Deduct 21 from 27 and we're left with 6.
Include the next digit (6) from the dividend after 6, then repeat: 66 / 7

On to step 6:
7 can be fit into 66 9 times, resulting in a remainder of 3.
Put 9 as the next digit of the answer. 
Result so far: 103939.0
If we take 63 away from 66, we end up 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.

Step 7:
If we divide 30 by 7, we get 4 and a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 103939.4
Subtracting 28 from 30 leaves us 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 8:
7 goes into 20 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 103939.42
If we take 14 away from 20, we end up with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Step 9:
When dividing 60 by 7, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 103939.428
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.

Advancing to step 10:
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: 103939.4285
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.

Going ahead to step 11:
When dividing 50 by 7, we get 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 103939.42857
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.

Moving on to step 12:
10 divided by 7 is 1 with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 103939.428571
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.

Going ahead to step 13:
When dividing 30 by 7, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 103939.4285714
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 14:
When dividing 20 by 7, we get 2 with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 103939.42857142
Deduct 14 from 20 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Our division results in 103939.42857142 with a remaining 6e-09.
