We look at the division of 802552 by 7 
The aim is to understand the frequency of 7 in 802552.

Let's proceed to step 1:
If we divide 8 by 7, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
Subtract 7 from 8 to get 1.
Fetch the next digit (0) from the dividend, attach it to 1 and continue: 10 / 7

On to step 2:
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: 11.0
Subtract 7 from 10 to get 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 7

Let's proceed to step 3:
7 goes into 32 4 times with a remainder of 4.
The next digit of our result is 4. 
Result so far: 114.0
If we take 28 away from 32, we end up with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 7

Moving on to step 4:
When dividing 45 by 7, we get 6 with a remainder of 3.
The number 6 becomes the next digit in our result. 
Result so far: 1146.0
If we subtract 42 from 45, we get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 7

Let's proceed to step 5:
When dividing 35 by 7, we get 5 with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 11465.0
If we subtract 35 from 35, we get 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 7

Step 6:
The number 7 fits into 2 0 times, leaving a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 114650.0
Subtracting 0 from 2 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.

Moving on to step 7:
7 goes into 20 2 times with a remainder of 6.
Put 2 as the next digit of the answer. 
Result so far: 114650.2
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.

Advancing to step 8:
The number 7 fits into 60 8 times, leaving a remainder of 4.
The number 8 becomes the next digit in our result. 
Result so far: 114650.28
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.

Let's proceed to step 9:
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: 114650.285
Subtract 35 from 40 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 10:
7 can be fit into 50 7 times, resulting in a remainder of 1.
The number 7 becomes the next digit in our result. 
Result so far: 114650.2857
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.

Moving on to step 11:
7 goes into 10 1 times with a remainder of 3.
The next digit of our result is 1. 
Result so far: 114650.28571
Deduct 7 from 10 and we're left 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 12:
If we divide 30 by 7, we get 4 and a remainder of 2.
The next digit of our result is 4. 
Result so far: 114650.285714
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.

Advancing to step 13:
7 goes into 20 2 times with a remainder of 6.
Record the quotient 2 as the next digit in the result. 
Result so far: 114650.2857142
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.

On to step 14:
When dividing 60 by 7, we get 8 with a remainder of 4.
Write down 8 as next digit of the result. 
Result so far: 114650.28571428
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.

In conclusion, the division gives 114650.28571428 with a balance of 4e-09.
