347670 ÷ 7 
The aim is to understand the frequency of 7 in 347670.

On to step 1:
3 divided by 7 is 0 with a remainder of 3.
Put 0 as the next digit of the answer. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Include the next digit (4) from the dividend after 3, then repeat: 34 / 7

On to step 2:
34 divided by 7 is 4 with a remainder of 6.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Subtract 28 from 34 to get 6.
Fetch the next digit (7) from the dividend, attach it to 6 and continue: 67 / 7

Going ahead to step 3:
If we divide 67 by 7, we get 9 and a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 49.0
If we take 63 away from 67, we end up with 4.
Bring next digit (6) of the dividend behind the 4 and repeat the process: 46 / 7

Let's proceed to step 4:
When dividing 46 by 7, we get 6 with a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 496.0
The remainder is 4 after subtracting 42 from 46.
Take the next digit (7) from the dividend and append it to 4, then repeat: 47 / 7

Advancing to step 5:
47 divided by 7 is 6 with a remainder of 5.
Put 6 as the next digit of the answer. 
Result so far: 4966.0
If we take 42 away from 47, we end up with 5.
Fetch the next digit (0) from the dividend, attach it to 5 and continue: 50 / 7

Let's proceed to step 6:
7 goes into 50 7 times with a remainder of 1.
Write down 7 as next digit of the result. 
Result so far: 49667.0
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.

Advancing to step 7:
7 goes into 10 1 times with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 49667.1
If we subtract 7 from 10, we 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.

Going ahead to step 8:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 49667.14
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 9:
20 divided by 7 is 2 with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 49667.142
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.

Advancing to step 10:
The number 7 fits into 60 8 times, leaving a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 49667.1428
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.

Step 11:
7 can be fit into 40 5 times, resulting in a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 49667.14285
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.

Let's proceed to step 12:
If we divide 50 by 7, we get 7 and a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 49667.142857
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.

Moving on to step 13:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 49667.1428571
If we subtract 7 from 10, we 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.

Moving on to step 14:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 49667.14285714
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.

The final result is 49667.14285714 with a remainder of 2e-09.
