Let's divide 594809 by 7
The aim is to understand the frequency of 7 in 594809.

Advancing to step 1:
7 goes into 5 0 times with a remainder of 5.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 5 leaves us with 5.
Take the next digit (9) from the dividend and append it to 5, then repeat: 59 / 7

Let's proceed to step 2:
The number 7 fits into 59 8 times, leaving a remainder of 3.
Record the quotient 8 as the next digit in the result. 
Result so far: 8.0
Subtracting 56 from 59 leaves us with 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 7

Advancing to step 3:
If we divide 34 by 7, we get 4 and a remainder of 6.
The next digit of our result is 4. 
Result so far: 84.0
The remainder is 6 after subtracting 28 from 34.
Include the next digit (8) from the dividend after 6, then repeat: 68 / 7

On to step 4:
The number 7 fits into 68 9 times, leaving a remainder of 5.
Write down 9 as next digit of the result. 
Result so far: 849.0
Deduct 63 from 68 and we're left with 5.
Include the next digit (0) from the dividend after 5, then repeat: 50 / 7

Let's proceed to step 5:
50 divided by 7 is 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 8497.0
If we subtract 49 from 50, we get 1.
Bring next digit (9) of the dividend behind the 1 and repeat the process: 19 / 7

On to step 6:
7 goes into 19 2 times with a remainder of 5.
Put 2 as the next digit of the answer. 
Result so far: 84972.0
If we subtract 14 from 19, 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.

Step 7:
When dividing 50 by 7, we get 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 84972.7
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:
When dividing 10 by 7, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 84972.71
If we subtract 7 from 10, we 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.

Going ahead to step 9:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 84972.714
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.

Step 10:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 84972.7142
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.

Advancing to step 11:
When dividing 60 by 7, we get 8 with a remainder of 4.
The next digit of our result is 8. 
Result so far: 84972.71428
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.

Advancing to step 12:
The number 7 fits into 40 5 times, leaving a remainder of 5.
The next digit of our result is 5. 
Result so far: 84972.714285
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.

Advancing to step 13:
When dividing 50 by 7, we get 7 with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 84972.7142857
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 14:
10 divided by 7 is 1 with a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 84972.71428571
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.

After the division, we end up with 84972.71428571 and a remainder of 3e-09.
