We look at the division of 149159 by 7 
The aim is to understand the frequency of 7 in 149159.

Moving on to step 1:
7 can be fit into 1 0 times, resulting in a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 1 after subtracting 0 from 1.
Bring next digit (4) of the dividend behind the 1 and repeat the process: 14 / 7

Going ahead to step 2:
If we divide 14 by 7, we get 2 and a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we subtract 14 from 14, we get 0.
Fetch the next digit (9) from the dividend, attach it to 0 and continue: 9 / 7

Step 3:
9 divided by 7 is 1 with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
If we subtract 7 from 9, we get 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 7

Step 4:
The number 7 fits into 21 3 times, leaving a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 213.0
Subtracting 21 from 21 leaves us with 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 7

Going ahead to step 5:
7 can be fit into 5 0 times, resulting in a remainder of 5.
The number 0 becomes the next digit in our result. 
Result so far: 2130.0
Subtract 0 from 5 to get 5.
Bring next digit (9) of the dividend behind the 5 and repeat the process: 59 / 7

On to step 6:
59 divided by 7 is 8 with a remainder of 3.
Write down 8 as next digit of the result. 
Result so far: 21308.0
The remainder is 3 after subtracting 56 from 59.
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 7:
30 divided by 7 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 21308.4
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.

On to step 8:
When dividing 20 by 7, we get 2 with a remainder of 6.
The next digit of our result is 2. 
Result so far: 21308.42
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.

Step 9:
If we divide 60 by 7, we get 8 and a remainder of 4.
The next digit of our result is 8. 
Result so far: 21308.428
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.

Going ahead to step 10:
40 divided by 7 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 21308.4285
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.

Let's proceed to step 11:
50 divided by 7 is 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 21308.42857
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.

Let's proceed to step 12:
7 goes into 10 1 times with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 21308.428571
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 13:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 21308.4285714
Subtract 28 from 30 to 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.

On to step 14:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 21308.42857142
Subtracting 14 from 20 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.

The final result is 21308.42857142 with a remainder of 6e-09.
