Let's divide 758949 by 7
The aim is to understand the frequency of 7 in 758949.

Going ahead to step 1:
The number 7 fits into 7 1 times, leaving a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtracting 7 from 7 leaves us with 0.
Include the next digit (5) from the dividend after 0, then repeat: 5 / 7

Step 2:
If we divide 5 by 7, we get 0 and a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 10.0
Subtracting 0 from 5 leaves us with 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 7

Going ahead to step 3:
The number 7 fits into 58 8 times, leaving a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 108.0
Subtract 56 from 58 to get 2.
Take the next digit (9) from the dividend and append it to 2, then repeat: 29 / 7

Let's proceed to step 4:
29 divided by 7 is 4 with a remainder of 1.
Use 4 as the next digit of our solution. 
Result so far: 1084.0
If we take 28 away from 29, we end up with 1.
Include the next digit (4) from the dividend after 1, then repeat: 14 / 7

On to step 5:
7 goes into 14 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 10842.0
If we take 14 away from 14, we end up with 0.
Append the next digit (9) from the dividend to 0 and continue with: 9 / 7

On to step 6:
If we divide 9 by 7, we get 1 and a remainder of 2.
Put 1 as the next digit of the answer. 
Result so far: 108421.0
Deduct 7 from 9 and we're left 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.

Step 7:
20 divided by 7 is 2 with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 108421.2
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 8:
The number 7 fits into 60 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 108421.28
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.

Going ahead to step 9:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 108421.285
Subtract 35 from 40 to 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.

Step 10:
The number 7 fits into 50 7 times, leaving a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 108421.2857
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.

On to step 11:
10 divided by 7 is 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 108421.28571
If we take 7 away from 10, 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.

Moving on to step 12:
7 goes into 30 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 108421.285714
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.

Going ahead to step 13:
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: 108421.2857142
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.

Advancing to step 14:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 108421.28571428
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.

The final outcome is 108421.28571428, with a leftover of 4e-09.
