We look at the division of 463883 by 7 
The aim is to understand the frequency of 7 in 463883.

Going ahead to step 1:
If we divide 4 by 7, we get 0 and a remainder of 4.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Fetch the next digit (6) from the dividend, attach it to 4 and continue: 46 / 7

Going ahead to step 2:
46 divided by 7 is 6 with a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 6.0
If we take 42 away from 46, we end up with 4.
Include the next digit (3) from the dividend after 4, then repeat: 43 / 7

Step 3:
If we divide 43 by 7, we get 6 and a remainder of 1.
The number 6 becomes the next digit in our result. 
Result so far: 66.0
If we take 42 away from 43, we end up with 1.
Fetch the next digit (8) from the dividend, attach it to 1 and continue: 18 / 7

Moving on to step 4:
18 divided by 7 is 2 with a remainder of 4.
Put 2 as the next digit of the answer. 
Result so far: 662.0
The remainder is 4 after subtracting 14 from 18.
Fetch the next digit (8) from the dividend, attach it to 4 and continue: 48 / 7

Step 5:
7 goes into 48 6 times with a remainder of 6.
Write down 6 as next digit of the result. 
Result so far: 6626.0
Deduct 42 from 48 and we're left with 6.
Append the next digit (3) from the dividend to 6 and continue with: 63 / 7

Moving on to step 6:
7 goes into 63 9 times with a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 66269.0
The remainder is 0 after subtracting 63 from 63.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
If we divide 0 by 7, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 66269.0
Subtracting 0 from 0 leaves us with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
0 divided by 7 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 66269.0
If we take 0 away from 0, we end up with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

After the division, we end up with 66269.0 and a remainder of 0.0.
