We divide 412812 by 7
The aim is to understand the frequency of 7 in 412812.

Advancing to step 1:
7 goes into 4 0 times with a remainder of 4.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 4 to get 4.
Fetch the next digit (1) from the dividend, attach it to 4 and continue: 41 / 7

Going ahead to step 2:
7 can be fit into 41 5 times, resulting in a remainder of 6.
Record the quotient 5 as the next digit in the result. 
Result so far: 5.0
Deduct 35 from 41 and we're left with 6.
Include the next digit (2) from the dividend after 6, then repeat: 62 / 7

Advancing to step 3:
7 can be fit into 62 8 times, resulting in a remainder of 6.
Write down 8 as next digit of the result. 
Result so far: 58.0
If we take 56 away from 62, we end up with 6.
Take the next digit (8) from the dividend and append it to 6, then repeat: 68 / 7

On to step 4:
7 goes into 68 9 times with a remainder of 5.
Use 9 as the next digit of our solution. 
Result so far: 589.0
If we subtract 63 from 68, we get 5.
Take the next digit (1) from the dividend and append it to 5, then repeat: 51 / 7

Let's proceed to step 5:
If we divide 51 by 7, we get 7 and a remainder of 2.
Put 7 as the next digit of the answer. 
Result so far: 5897.0
Subtract 49 from 51 to get 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 7

Going ahead to step 6:
If we divide 22 by 7, we get 3 and a remainder of 1.
The next digit of our result is 3. 
Result so far: 58973.0
If we take 21 away from 22, 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.

Step 7:
7 goes into 10 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 58973.1
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.

On to step 8:
If we divide 30 by 7, we get 4 and a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 58973.14
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.

Step 9:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 58973.142
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.

On to step 10:
When dividing 60 by 7, we get 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 58973.1428
Subtracting 56 from 60 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Going ahead to step 11:
7 goes into 40 5 times with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 58973.14285
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.

Let's proceed to step 12:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 58973.142857
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 13:
7 goes into 10 1 times with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 58973.1428571
If we take 7 away from 10, we end up 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.

On to step 14:
If we divide 30 by 7, we get 4 and a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 58973.14285714
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 result is 58973.14285714 with a remainder of 2e-09.
