We look at the division of 12276 by 7 
The aim is to understand the frequency of 7 in 12276.

Moving on to step 1:
7 goes into 1 0 times with a remainder of 1.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 1 and we're left with 1.
Append the next digit (2) from the dividend to 1 and continue with: 12 / 7

Moving on to step 2:
12 divided by 7 is 1 with a remainder of 5.
Put 1 as the next digit of the answer. 
Result so far: 1.0
Subtract 7 from 12 to get 5.
Fetch the next digit (2) from the dividend, attach it to 5 and continue: 52 / 7

On to step 3:
52 divided by 7 is 7 with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 17.0
If we take 49 away from 52, we end up with 3.
Take the next digit (7) from the dividend and append it to 3, then repeat: 37 / 7

On to step 4:
If we divide 37 by 7, we get 5 and a remainder of 2.
Put 5 as the next digit of the answer. 
Result so far: 175.0
If we subtract 35 from 37, we get 2.
Append the next digit (6) from the dividend to 2 and continue with: 26 / 7

Moving on to step 5:
7 goes into 26 3 times with a remainder of 5.
The next digit of our result is 3. 
Result so far: 1753.0
If we take 21 away from 26, we end up 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.

Step 6:
50 divided by 7 is 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 1753.7
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 7:
When dividing 10 by 7, we get 1 with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 1753.71
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.

Step 8:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 1753.714
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.

Step 9:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 1753.7142
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.

Moving on to step 10:
The number 7 fits into 60 8 times, leaving a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 1753.71428
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.

Let's proceed to step 11:
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: 1753.714285
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.

Moving on to step 12:
The number 7 fits into 50 7 times, leaving a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 1753.7142857
Subtracting 49 from 50 leaves us 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.

On to step 13:
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: 1753.71428571
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.

After the division, we end up with 1753.71428571 and a remainder of 3e-09.
