We're dividing 630297 by 7 
The aim is to understand the frequency of 7 in 630297.

Let's proceed to step 1:
6 divided by 7 is 0 with a remainder of 6.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 6 and we're left with 6.
Bring next digit (3) of the dividend behind the 6 and repeat the process: 63 / 7

Let's proceed to step 2:
When dividing 63 by 7, we get 9 with a remainder of 0.
Put 9 as the next digit of the answer. 
Result so far: 9.0
If we subtract 63 from 63, we get 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 7

Step 3:
7 goes into 0 0 times with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 90.0
Deduct 0 from 0 and we're left with 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 7

Let's proceed to step 4:
2 divided by 7 is 0 with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 900.0
If we take 0 away from 2, we end up with 2.
Include the next digit (9) from the dividend after 2, then repeat: 29 / 7

Advancing to step 5:
29 divided by 7 is 4 with a remainder of 1.
Write down 4 as next digit of the result. 
Result so far: 9004.0
If we take 28 away from 29, we end up with 1.
Include the next digit (7) from the dividend after 1, then repeat: 17 / 7

On to step 6:
The number 7 fits into 17 2 times, leaving a remainder of 3.
Write down 2 as next digit of the result. 
Result so far: 90042.0
Deduct 14 from 17 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.

Going ahead to step 7:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 90042.4
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 8:
If we divide 20 by 7, we get 2 and a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 90042.42
Deduct 14 from 20 and we're left 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.

Let's proceed to step 9:
When dividing 60 by 7, we get 8 with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 90042.428
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 10:
When dividing 40 by 7, we get 5 with a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 90042.4285
If we subtract 35 from 40, we 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 11:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 90042.42857
The remainder is 1 after subtracting 49 from 50.
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 12:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 90042.428571
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.

Advancing to step 13:
7 goes into 30 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 90042.4285714
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.

Moving on to step 14:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 90042.42857142
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.

The final result is 90042.42857142 with a remainder of 6e-09.
