212047 ÷ 7 
The aim is to understand the frequency of 7 in 212047.

Going ahead to step 1:
The number 7 fits into 2 0 times, leaving a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Include the next digit (1) from the dividend after 2, then repeat: 21 / 7

On to step 2:
The number 7 fits into 21 3 times, leaving a remainder of 0.
The next digit of our result is 3. 
Result so far: 3.0
Subtracting 21 from 21 leaves us with 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 7

Step 3:
When dividing 2 by 7, we get 0 with a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 30.0
Subtracting 0 from 2 leaves us with 2.
Grab the next digit (0) from the dividend, add it to 2, then carry on: 20 / 7

On to step 4:
The number 7 fits into 20 2 times, leaving a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 302.0
Subtract 14 from 20 to get 6.
Grab the next digit (4) from the dividend, add it to 6, then carry on: 64 / 7

Let's proceed to step 5:
7 goes into 64 9 times with a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 3029.0
Subtract 63 from 64 to get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 7

Advancing to step 6:
When dividing 17 by 7, we get 2 with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 30292.0
Subtracting 14 from 17 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.

Step 7:
7 can be fit into 30 4 times, resulting in a remainder of 2.
Write down 4 as next digit of the result. 
Result so far: 30292.4
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.

Advancing to step 8:
7 can be fit into 20 2 times, resulting in a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 30292.42
Subtracting 14 from 20 leaves us 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.

Step 9:
7 goes into 60 8 times with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 30292.428
If we subtract 56 from 60, we 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.

Step 10:
7 can be fit into 40 5 times, resulting in a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 30292.4285
If we take 35 away from 40, 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 11:
If we divide 50 by 7, we get 7 and a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 30292.42857
If we take 49 away from 50, 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.

Advancing to step 12:
When dividing 10 by 7, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 30292.428571
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.

On to step 13:
30 divided by 7 is 4 with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 30292.4285714
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.

Let's proceed to step 14:
7 goes into 20 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 30292.42857142
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.

After the division, we end up with 30292.42857142 and a remainder of 6e-09.
