Let's divide 67443 by 7
The aim is to understand the frequency of 7 in 67443.

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
Subtracting 0 from 6 leaves us with 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 7

Advancing to step 2:
67 divided by 7 is 9 with a remainder of 4.
The number 9 becomes the next digit in our result. 
Result so far: 9.0
If we subtract 63 from 67, we get 4.
Grab the next digit (4) from the dividend, add it to 4, then carry on: 44 / 7

Going ahead to step 3:
The number 7 fits into 44 6 times, leaving a remainder of 2.
Record the quotient 6 as the next digit in the result. 
Result so far: 96.0
The remainder is 2 after subtracting 42 from 44.
Fetch the next digit (4) from the dividend, attach it to 2 and continue: 24 / 7

Going ahead to step 4:
The number 7 fits into 24 3 times, leaving a remainder of 3.
The next digit of our result is 3. 
Result so far: 963.0
If we subtract 21 from 24, we get 3.
Bring next digit (3) of the dividend behind the 3 and repeat the process: 33 / 7

Going ahead to step 5:
The number 7 fits into 33 4 times, leaving a remainder of 5.
The number 4 becomes the next digit in our result. 
Result so far: 9634.0
Subtracting 28 from 33 leaves us 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.

Going ahead to step 6:
If we divide 50 by 7, we get 7 and a remainder of 1.
The next digit of our result is 7. 
Result so far: 9634.7
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.

Moving on to step 7:
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: 9634.71
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.

Advancing to step 8:
7 goes into 30 4 times with a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 9634.714
The remainder is 2 after subtracting 28 from 30.
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 9:
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: 9634.7142
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.

Step 10:
If we divide 60 by 7, we get 8 and a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 9634.71428
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.

Moving on to step 11:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 9634.714285
Subtracting 35 from 40 leaves us 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:
When dividing 50 by 7, we get 7 with a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 9634.7142857
Subtract 49 from 50 to 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.

Going ahead to step 13:
The number 7 fits into 10 1 times, leaving a remainder of 3.
Put 1 as the next digit of the answer. 
Result so far: 9634.71428571
The remainder is 3 after subtracting 7 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

The quotient of the division is 9634.71428571, and the remainder is 3e-09.
