Let's divide 964913 by 7
The aim is to understand the frequency of 7 in 964913.

Going ahead to step 1:
7 can be fit into 9 1 times, resulting in a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1.0
The remainder is 2 after subtracting 7 from 9.
Grab the next digit (6) from the dividend, add it to 2, then carry on: 26 / 7

Moving on to step 2:
If we divide 26 by 7, we get 3 and a remainder of 5.
The next digit of our result is 3. 
Result so far: 13.0
If we take 21 away from 26, we end up with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 7

Step 3:
54 divided by 7 is 7 with a remainder of 5.
Record the quotient 7 as the next digit in the result. 
Result so far: 137.0
If we take 49 away from 54, we end up with 5.
Grab the next digit (9) from the dividend, add it to 5, then carry on: 59 / 7

Going ahead to step 4:
7 goes into 59 8 times with a remainder of 3.
The next digit of our result is 8. 
Result so far: 1378.0
Subtracting 56 from 59 leaves us with 3.
Append the next digit (1) from the dividend to 3 and continue with: 31 / 7

Advancing to step 5:
If we divide 31 by 7, we get 4 and a remainder of 3.
The number 4 becomes the next digit in our result. 
Result so far: 13784.0
Subtract 28 from 31 to get 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 7

Let's proceed to step 6:
The number 7 fits into 33 4 times, leaving a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 137844.0
If we subtract 28 from 33, 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.

Advancing to step 7:
When dividing 50 by 7, we get 7 with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 137844.7
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 8:
7 goes into 10 1 times with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 137844.71
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.

Going ahead to step 9:
The number 7 fits into 30 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 137844.714
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.

On to step 10:
The number 7 fits into 20 2 times, leaving a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 137844.7142
Subtract 14 from 20 to 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.

Moving on to step 11:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 137844.71428
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.

Step 12:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Put 5 as the next digit of the answer. 
Result so far: 137844.714285
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.

Step 13:
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: 137844.7142857
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.

Going ahead to step 14:
When dividing 10 by 7, we get 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 137844.71428571
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.

The final result is 137844.71428571 with a remainder of 3e-09.
