We look at the division of 632558 by 7 
The aim is to understand the frequency of 7 in 632558.

Step 1:
If we divide 6 by 7, we get 0 and a remainder of 6.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Include the next digit (3) from the dividend after 6, then repeat: 63 / 7

On to step 2:
When dividing 63 by 7, we get 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
Subtract 63 from 63 to get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 7

Let's proceed to step 3:
7 goes into 2 0 times with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 90.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (5) from the dividend and append it to 2, then repeat: 25 / 7

Going ahead to step 4:
25 divided by 7 is 3 with a remainder of 4.
The number 3 becomes the next digit in our result. 
Result so far: 903.0
Subtract 21 from 25 to get 4.
Take the next digit (5) from the dividend and append it to 4, then repeat: 45 / 7

Moving on to step 5:
7 goes into 45 6 times with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 9036.0
The remainder is 3 after subtracting 42 from 45.
Fetch the next digit (8) from the dividend, attach it to 3 and continue: 38 / 7

On to step 6:
7 goes into 38 5 times with a remainder of 3.
Write down 5 as next digit of the result. 
Result so far: 90365.0
The remainder is 3 after subtracting 35 from 38.
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 7:
When dividing 30 by 7, we get 4 with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 90365.4
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.

On to step 8:
The number 7 fits into 20 2 times, leaving a remainder of 6.
The next digit of our result is 2. 
Result so far: 90365.42
Subtract 14 from 20 to 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.

On to step 9:
60 divided by 7 is 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 90365.428
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.

Step 10:
If we divide 40 by 7, we get 5 and a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 90365.4285
Deduct 35 from 40 and we're left with 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 11:
When dividing 50 by 7, we get 7 with a remainder of 1.
Record the quotient 7 as the next digit in the result. 
Result so far: 90365.42857
If we subtract 49 from 50, we 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.

Step 12:
When dividing 10 by 7, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 90365.428571
Subtracting 7 from 10 leaves us 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 13:
7 goes into 30 4 times with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 90365.4285714
Deduct 28 from 30 and we're left 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 14:
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: 90365.42857142
Subtract 14 from 20 to 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.

The final outcome is 90365.42857142, with a leftover of 6e-09.
