We divide 409149 by 7
The aim is to understand the frequency of 7 in 409149.

Going ahead to step 1:
If we divide 4 by 7, we get 0 and a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (0) from the dividend and append it to 4, then repeat: 40 / 7

Step 2:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
If we subtract 35 from 40, we get 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 7

Advancing to step 3:
The number 7 fits into 59 8 times, leaving a remainder of 3.
The number 8 becomes the next digit in our result. 
Result so far: 58.0
Subtract 56 from 59 to get 3.
Grab the next digit (1) from the dividend, add it to 3, then carry on: 31 / 7

Advancing to step 4:
7 can be fit into 31 4 times, resulting in a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 584.0
Subtracting 28 from 31 leaves us with 3.
Grab the next digit (4) from the dividend, add it to 3, then carry on: 34 / 7

Advancing to step 5:
If we divide 34 by 7, we get 4 and a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 5844.0
Subtracting 28 from 34 leaves us with 6.
Include the next digit (9) from the dividend after 6, then repeat: 69 / 7

Step 6:
7 can be fit into 69 9 times, resulting in a remainder of 6.
Put 9 as the next digit of the answer. 
Result so far: 58449.0
Subtracting 63 from 69 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.

On to step 7:
The number 7 fits into 60 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 58449.8
Deduct 56 from 60 and we're left 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.

Going ahead to step 8:
40 divided by 7 is 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 58449.85
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 9:
If we divide 50 by 7, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 58449.857
The remainder is 1 after subtracting 49 from 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Let's proceed to step 10:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 58449.8571
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.

Advancing to step 11:
7 goes into 30 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 58449.85714
If we subtract 28 from 30, we 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.

Going ahead to step 12:
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: 58449.857142
The remainder is 6 after subtracting 14 from 20.
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:
If we divide 60 by 7, we get 8 and a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 58449.8571428
The remainder is 4 after subtracting 56 from 60.
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 14:
40 divided by 7 is 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 58449.85714285
If we subtract 35 from 40, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

The quotient of the division is 58449.85714285, and the remainder is 5e-09.
