497456 divided by 7 
The aim is to understand the frequency of 7 in 497456.

Let's proceed to step 1:
When dividing 4 by 7, we get 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Take the next digit (9) from the dividend and append it to 4, then repeat: 49 / 7

Moving on to step 2:
7 can be fit into 49 7 times, resulting in 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.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 7

Let's proceed to step 3:
7 goes into 7 1 times with a remainder of 0.
Put 1 as the next digit of the answer. 
Result so far: 71.0
Deduct 7 from 7 and we're left with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 7

Advancing to step 4:
The number 7 fits into 4 0 times, leaving a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 710.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (5) from the dividend, attach it to 4 and continue: 45 / 7

Advancing to step 5:
45 divided by 7 is 6 with a remainder of 3.
Put 6 as the next digit of the answer. 
Result so far: 7106.0
If we subtract 42 from 45, we get 3.
Fetch the next digit (6) from the dividend, attach it to 3 and continue: 36 / 7

Moving on to step 6:
If we divide 36 by 7, we get 5 and a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 71065.0
The remainder is 1 after subtracting 35 from 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Advancing to step 7:
7 goes into 10 1 times with a remainder of 3.
The next digit of our result is 1. 
Result so far: 71065.1
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 8:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 71065.14
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 9:
7 goes into 20 2 times with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 71065.142
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 10:
60 divided by 7 is 8 with a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 71065.1428
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.

Moving on to step 11:
7 can be fit into 40 5 times, resulting in a remainder of 5.
The next digit of our result is 5. 
Result so far: 71065.14285
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.

Going ahead to step 12:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 71065.142857
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.

Moving on to step 13:
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: 71065.1428571
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 14:
The number 7 fits into 30 4 times, leaving a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 71065.14285714
The remainder is 2 after subtracting 28 from 30.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The quotient of the division is 71065.14285714, and the remainder is 2e-09.
