We look at the division of 486935 by 7 
The aim is to understand the frequency of 7 in 486935.

Moving on to step 1:
The number 7 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 4 after subtracting 0 from 4.
Take the next digit (8) from the dividend and append it to 4, then repeat: 48 / 7

Step 2:
The number 7 fits into 48 6 times, leaving a remainder of 6.
The next digit of our result is 6. 
Result so far: 6.0
The remainder is 6 after subtracting 42 from 48.
Bring next digit (6) of the dividend behind the 6 and repeat the process: 66 / 7

Moving on to step 3:
The number 7 fits into 66 9 times, leaving a remainder of 3.
The number 9 becomes the next digit in our result. 
Result so far: 69.0
If we take 63 away from 66, we end up with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 7

Step 4:
When dividing 39 by 7, we get 5 with a remainder of 4.
The next digit of our result is 5. 
Result so far: 695.0
The remainder is 4 after subtracting 35 from 39.
Grab the next digit (3) from the dividend, add it to 4, then carry on: 43 / 7

On to step 5:
43 divided by 7 is 6 with a remainder of 1.
Use 6 as the next digit of our solution. 
Result so far: 6956.0
If we take 42 away from 43, we end up with 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 7

Moving on to step 6:
If we divide 15 by 7, we get 2 and a remainder of 1.
Record the quotient 2 as the next digit in the result. 
Result so far: 69562.0
The remainder is 1 after subtracting 14 from 15.
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 7:
If we divide 10 by 7, we get 1 and a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 69562.1
Deduct 7 from 10 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 8:
7 goes into 30 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 69562.14
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.

Step 9:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 69562.142
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.

On to step 10:
60 divided by 7 is 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 69562.1428
If we subtract 56 from 60, we 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:
40 divided by 7 is 5 with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 69562.14285
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.

Step 12:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 69562.142857
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 13:
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: 69562.1428571
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.

Let's proceed to step 14:
30 divided by 7 is 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 69562.14285714
If we take 28 away from 30, we end up 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.

The final outcome is 69562.14285714, with a leftover of 2e-09.
