We're dividing 702064 by 7 
The aim is to understand the frequency of 7 in 702064.

Step 1:
If we divide 7 by 7, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 7 from 7 leaves us with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 7

Let's proceed to step 2:
7 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 0 after subtracting 0 from 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 7

Let's proceed to step 3:
If we divide 2 by 7, we get 0 and a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 100.0
If we take 0 away from 2, we end up with 2.
Append the next digit (0) from the dividend to 2 and continue with: 20 / 7

Going ahead to step 4:
When dividing 20 by 7, we get 2 with a remainder of 6.
Use 2 as the next digit of our solution. 
Result so far: 1002.0
Subtract 14 from 20 to get 6.
Fetch the next digit (6) from the dividend, attach it to 6 and continue: 66 / 7

Advancing to step 5:
66 divided by 7 is 9 with a remainder of 3.
The next digit of our result is 9. 
Result so far: 10029.0
Deduct 63 from 66 and we're left with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 7

Advancing to step 6:
When dividing 34 by 7, we get 4 with a remainder of 6.
The next digit of our result is 4. 
Result so far: 100294.0
The remainder is 6 after subtracting 28 from 34.
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 7:
60 divided by 7 is 8 with a remainder of 4.
Record the quotient 8 as the next digit in the result. 
Result so far: 100294.8
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.

Let's proceed to step 8:
If we divide 40 by 7, we get 5 and a remainder of 5.
Record the quotient 5 as the next digit in the result. 
Result so far: 100294.85
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.

Going ahead to step 9:
When dividing 50 by 7, we get 7 with a remainder of 1.
Use 7 as the next digit of our solution. 
Result so far: 100294.857
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.

Step 10:
When dividing 10 by 7, we get 1 with a remainder of 3.
The next digit of our result is 1. 
Result so far: 100294.8571
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.

Let's proceed to step 11:
When dividing 30 by 7, we get 4 with a remainder of 2.
Put 4 as the next digit of the answer. 
Result so far: 100294.85714
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.

On to step 12:
7 goes into 20 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 100294.857142
Subtracting 14 from 20 leaves us with 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 13:
7 goes into 60 8 times with a remainder of 4.
Use 8 as the next digit of our solution. 
Result so far: 100294.8571428
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.

On to step 14:
The number 7 fits into 40 5 times, leaving a remainder of 5.
Use 5 as the next digit of our solution. 
Result so far: 100294.85714285
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.

In conclusion, the division gives 100294.85714285 with a balance of 5e-09.
