669462 divided by 7 
The aim is to understand the frequency of 7 in 669462.

Let's proceed to step 1:
6 divided by 7 is 0 with a remainder of 6.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 6, we get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 7

Advancing to step 2:
7 can be fit into 66 9 times, resulting in a remainder of 3.
Use 9 as the next digit of our solution. 
Result so far: 9.0
Subtract 63 from 66 to get 3.
Fetch the next digit (9) from the dividend, attach it to 3 and continue: 39 / 7

Step 3:
The number 7 fits into 39 5 times, leaving a remainder of 4.
Put 5 as the next digit of the answer. 
Result so far: 95.0
Subtract 35 from 39 to get 4.
Bring next digit (4) of the dividend behind the 4 and repeat the process: 44 / 7

Going ahead to step 4:
If we divide 44 by 7, we get 6 and a remainder of 2.
Write down 6 as next digit of the result. 
Result so far: 956.0
Subtracting 42 from 44 leaves us with 2.
Bring next digit (6) of the dividend behind the 2 and repeat the process: 26 / 7

Advancing to step 5:
7 can be fit into 26 3 times, resulting in a remainder of 5.
Use 3 as the next digit of our solution. 
Result so far: 9563.0
If we subtract 21 from 26, we get 5.
Include the next digit (2) from the dividend after 5, then repeat: 52 / 7

Advancing to step 6:
7 goes into 52 7 times with a remainder of 3.
The next digit of our result is 7. 
Result so far: 95637.0
Deduct 49 from 52 and we're left 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.

Advancing to step 7:
When dividing 30 by 7, we get 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 95637.4
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.

Moving on to step 8:
7 goes into 20 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 95637.42
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.

On to step 9:
60 divided by 7 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 95637.428
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Let's proceed to step 10:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 95637.4285
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.

Going ahead to step 11:
50 divided by 7 is 7 with a remainder of 1.
The next digit of our result is 7. 
Result so far: 95637.42857
If we take 49 away from 50, we end up 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 12:
7 goes into 10 1 times with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 95637.428571
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.

Moving on to step 13:
The number 7 fits into 30 4 times, leaving a remainder of 2.
The next digit of our result is 4. 
Result so far: 95637.4285714
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.

Going ahead to step 14:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 95637.42857142
Subtracting 14 from 20 leaves us 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.

The final result is 95637.42857142 with a remainder of 6e-09.
