Let's divide 547125 by 7
The aim is to understand the frequency of 7 in 547125.

Moving on to step 1:
The number 7 fits into 5 0 times, leaving a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 5 to get 5.
Grab the next digit (4) from the dividend, add it to 5, then carry on: 54 / 7

Going ahead to step 2:
When dividing 54 by 7, we get 7 with a remainder of 5.
The number 7 becomes the next digit in our result. 
Result so far: 7.0
If we subtract 49 from 54, we get 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 7

Moving on to step 3:
If we divide 57 by 7, we get 8 and a remainder of 1.
The next digit of our result is 8. 
Result so far: 78.0
The remainder is 1 after subtracting 56 from 57.
Bring next digit (1) of the dividend behind the 1 and repeat the process: 11 / 7

Going ahead to step 4:
11 divided by 7 is 1 with a remainder of 4.
Record the quotient 1 as the next digit in the result. 
Result so far: 781.0
If we take 7 away from 11, we end up with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 7

Let's proceed to step 5:
The number 7 fits into 42 6 times, leaving a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 7816.0
The remainder is 0 after subtracting 42 from 42.
Fetch the next digit (5) from the dividend, attach it to 0 and continue: 5 / 7

Advancing to step 6:
The number 7 fits into 5 0 times, leaving a remainder of 5.
Use 0 as the next digit of our solution. 
Result so far: 78160.0
If we subtract 0 from 5, we get 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 7:
The number 7 fits into 50 7 times, leaving a remainder of 1.
The next digit of our result is 7. 
Result so far: 78160.7
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.

Let's proceed to step 8:
7 can be fit into 10 1 times, resulting in a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 78160.71
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.

On to step 9:
30 divided by 7 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 78160.714
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.

Let's proceed to step 10:
7 goes into 20 2 times with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 78160.7142
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.

On to step 11:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Put 8 as the next digit of the answer. 
Result so far: 78160.71428
If we take 56 away from 60, we end up 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.

Advancing to step 12:
7 goes into 40 5 times with a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 78160.714285
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.

Going ahead to step 13:
7 can be fit into 50 7 times, resulting in a remainder of 1.
Put 7 as the next digit of the answer. 
Result so far: 78160.7142857
The remainder is 1 after subtracting 49 from 50.
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 14:
If we divide 10 by 7, we get 1 and a remainder of 3.
The next digit of our result is 1. 
Result so far: 78160.71428571
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.

The final result is 78160.71428571 with a remainder of 3e-09.
