We divide 714128 by 7
The aim is to understand the frequency of 7 in 714128.

On to step 1:
When dividing 7 by 7, we get 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 7 from 7, we get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 7

Step 2:
The number 7 fits into 1 0 times, leaving a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 10.0
If we take 0 away from 1, we end up with 1.
Grab the next digit (4) from the dividend, add it to 1, then carry on: 14 / 7

On to step 3:
7 goes into 14 2 times with a remainder of 0.
The next digit of our result is 2. 
Result so far: 102.0
The remainder is 0 after subtracting 14 from 14.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 7

Moving on to step 4:
When dividing 1 by 7, we get 0 with a remainder of 1.
Put 0 as the next digit of the answer. 
Result so far: 1020.0
Subtract 0 from 1 to get 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 7

Going ahead to step 5:
The number 7 fits into 12 1 times, leaving a remainder of 5.
The number 1 becomes the next digit in our result. 
Result so far: 10201.0
Subtract 7 from 12 to get 5.
Include the next digit (8) from the dividend after 5, then repeat: 58 / 7

Let's proceed to step 6:
7 can be fit into 58 8 times, resulting in a remainder of 2.
Write down 8 as next digit of the result. 
Result so far: 102018.0
Deduct 56 from 58 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.

Moving on to step 7:
If we divide 20 by 7, we get 2 and a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 102018.2
The remainder is 6 after subtracting 14 from 20.
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 8:
If we divide 60 by 7, we get 8 and a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 102018.28
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.

On to step 9:
40 divided by 7 is 5 with a remainder of 5.
The next digit of our result is 5. 
Result so far: 102018.285
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 10:
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: 102018.2857
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.

Advancing to step 11:
7 goes into 10 1 times with a remainder of 3.
The number 1 becomes the next digit in our result. 
Result so far: 102018.28571
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.

Advancing to step 12:
The number 7 fits into 30 4 times, leaving a remainder of 2.
Record the quotient 4 as the next digit in the result. 
Result so far: 102018.285714
Subtracting 28 from 30 leaves us 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.

Going ahead to step 13:
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: 102018.2857142
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.

Step 14:
The number 7 fits into 60 8 times, leaving a remainder of 4.
The next digit of our result is 8. 
Result so far: 102018.28571428
The remainder is 4 after subtracting 56 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The final result is 102018.28571428 with a remainder of 4e-09.
