808031 ÷ 7 
The aim is to understand the frequency of 7 in 808031.

Step 1:
7 can be fit into 8 1 times, resulting in a remainder of 1.
The next digit of our result is 1. 
Result so far: 1.0
If we take 7 away from 8, we end up with 1.
Bring next digit (0) of the dividend behind the 1 and repeat the process: 10 / 7

Step 2:
When dividing 10 by 7, we get 1 with a remainder of 3.
Use 1 as the next digit of our solution. 
Result so far: 11.0
If we subtract 7 from 10, we get 3.
Append the next digit (8) from the dividend to 3 and continue with: 38 / 7

On to step 3:
The number 7 fits into 38 5 times, leaving a remainder of 3.
The number 5 becomes the next digit in our result. 
Result so far: 115.0
If we subtract 35 from 38, we get 3.
Fetch the next digit (0) from the dividend, attach it to 3 and continue: 30 / 7

Let's proceed to step 4:
7 can be fit into 30 4 times, resulting in a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 1154.0
If we subtract 28 from 30, we get 2.
Bring next digit (3) of the dividend behind the 2 and repeat the process: 23 / 7

On to step 5:
If we divide 23 by 7, we get 3 and a remainder of 2.
Record the quotient 3 as the next digit in the result. 
Result so far: 11543.0
If we subtract 21 from 23, we get 2.
Append the next digit (1) from the dividend to 2 and continue with: 21 / 7

Going ahead to step 6:
When dividing 21 by 7, we get 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 115433.0
Deduct 21 from 21 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 7:
The number 7 fits into 0 0 times, leaving a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 115433.0
The remainder is 0 after subtracting 0 from 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Advancing to step 8:
The number 7 fits into 0 0 times, leaving a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 115433.0
Deduct 0 from 0 and we're left with 0.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

The quotient of the division is 115433.0, and the remainder is 0.0.
