We look at the division of 729784 by 7 
The aim is to understand the frequency of 7 in 729784.

Moving on 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
Deduct 7 from 7 and we're left with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 7

On to step 2:
2 divided by 7 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 10.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 7

Step 3:
7 can be fit into 29 4 times, resulting in a remainder of 1.
Put 4 as the next digit of the answer. 
Result so far: 104.0
If we take 28 away from 29, we end up with 1.
Append the next digit (7) from the dividend to 1 and continue with: 17 / 7

Going ahead to step 4:
When dividing 17 by 7, we get 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 1042.0
Subtract 14 from 17 to get 3.
Include the next digit (8) from the dividend after 3, then repeat: 38 / 7

Let's proceed to step 5:
If we divide 38 by 7, we get 5 and a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 10425.0
Deduct 35 from 38 and we're left with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 7

Advancing to step 6:
7 can be fit into 34 4 times, resulting in a remainder of 6.
The number 4 becomes the next digit in our result. 
Result so far: 104254.0
Subtracting 28 from 34 leaves us 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.

Going ahead to step 7:
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: 104254.8
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.

Let's proceed to step 8:
40 divided by 7 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 104254.85
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.

Let's proceed to step 9:
If we divide 50 by 7, we get 7 and a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 104254.857
Subtract 49 from 50 to 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.

Step 10:
10 divided by 7 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 104254.8571
Subtracting 7 from 10 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.

Let's proceed to step 11:
7 goes into 30 4 times with a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 104254.85714
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 12:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 104254.857142
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 13:
When dividing 60 by 7, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 104254.8571428
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 14:
7 can be fit into 40 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 104254.85714285
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.

After the division, we end up with 104254.85714285 and a remainder of 5e-09.
