We divide 715237 by 7
The aim is to understand the frequency of 7 in 715237.

Advancing to step 1:
7 can be fit into 7 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 7 from 7 and we're left with 0.
Take the next digit (1) from the dividend and append it to 0, then repeat: 1 / 7

Going ahead to step 2:
If we divide 1 by 7, we get 0 and a remainder of 1.
Use 0 as the next digit of our solution. 
Result so far: 10.0
Deduct 0 from 1 and we're left with 1.
Take the next digit (5) from the dividend and append it to 1, then repeat: 15 / 7

Moving on to step 3:
If we divide 15 by 7, we get 2 and a remainder of 1.
The number 2 becomes the next digit in our result. 
Result so far: 102.0
Deduct 14 from 15 and we're left with 1.
Grab the next digit (2) from the dividend, add it to 1, then carry on: 12 / 7

Step 4:
7 goes into 12 1 times with a remainder of 5.
Record the quotient 1 as the next digit in the result. 
Result so far: 1021.0
Subtract 7 from 12 to get 5.
Bring next digit (3) of the dividend behind the 5 and repeat the process: 53 / 7

Moving on to step 5:
If we divide 53 by 7, we get 7 and a remainder of 4.
The next digit of our result is 7. 
Result so far: 10217.0
If we take 49 away from 53, we end up with 4.
Grab the next digit (7) from the dividend, add it to 4, then carry on: 47 / 7

Advancing to step 6:
47 divided by 7 is 6 with a remainder of 5.
Use 6 as the next digit of our solution. 
Result so far: 102176.0
Subtract 42 from 47 to 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.

Going ahead to step 7:
50 divided by 7 is 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 102176.7
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 8:
7 goes into 10 1 times with a remainder of 3.
Write down 1 as next digit of the result. 
Result so far: 102176.71
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.

Step 9:
30 divided by 7 is 4 with a remainder of 2.
The next digit of our result is 4. 
Result so far: 102176.714
If we subtract 28 from 30, we 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.

Moving on to step 10:
If we divide 20 by 7, we get 2 and a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 102176.7142
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.

Let's proceed to step 11:
7 can be fit into 60 8 times, resulting in a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 102176.71428
Deduct 56 from 60 and we're left 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.

Let's proceed to step 12:
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: 102176.714285
Deduct 35 from 40 and we're left 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.

Moving on to step 13:
7 goes into 50 7 times with a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 102176.7142857
Deduct 49 from 50 and we're left 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 14:
When dividing 10 by 7, we get 1 with a remainder of 3.
Record the quotient 1 as the next digit in the result. 
Result so far: 102176.71428571
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.

Our division results in 102176.71428571 with a remaining 3e-09.
