We're dividing 499343 by 7 
The aim is to understand the frequency of 7 in 499343.

Advancing to step 1:
4 divided by 7 is 0 with a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (9) from the dividend to 4 and continue with: 49 / 7

Step 2:
When dividing 49 by 7, we get 7 with a remainder of 0.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 49 from 49 to get 0.
Grab the next digit (9) from the dividend, add it to 0, then carry on: 9 / 7

Let's proceed to step 3:
7 goes into 9 1 times with a remainder of 2.
Record the quotient 1 as the next digit in the result. 
Result so far: 71.0
If we subtract 7 from 9, we get 2.
Grab the next digit (3) from the dividend, add it to 2, then carry on: 23 / 7

Moving on to step 4:
7 can be fit into 23 3 times, resulting in a remainder of 2.
Use 3 as the next digit of our solution. 
Result so far: 713.0
The remainder is 2 after subtracting 21 from 23.
Take the next digit (4) from the dividend and append it to 2, then repeat: 24 / 7

Let's proceed to step 5:
If we divide 24 by 7, we get 3 and a remainder of 3.
Write down 3 as next digit of the result. 
Result so far: 7133.0
If we subtract 21 from 24, we get 3.
Append the next digit (3) from the dividend to 3 and continue with: 33 / 7

Let's proceed to step 6:
7 goes into 33 4 times with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 71334.0
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.

Moving on to step 7:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 71334.7
Subtracting 49 from 50 leaves us with 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 8:
If we divide 10 by 7, we get 1 and a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 71334.71
The remainder is 3 after subtracting 7 from 10.
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 9:
7 goes into 30 4 times with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 71334.714
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 10:
7 goes into 20 2 times with a remainder of 6.
The number 2 becomes the next digit in our result. 
Result so far: 71334.7142
Deduct 14 from 20 and we're left 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.

Let's proceed 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: 71334.71428
If we take 56 away from 60, we end up 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 12:
7 goes into 40 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 71334.714285
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.

Moving on to step 13:
50 divided by 7 is 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 71334.7142857
Deduct 49 from 50 and we're left with 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 14:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 71334.71428571
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.

In conclusion, the division gives 71334.71428571 with a balance of 3e-09.
