Let's divide 80213712 by 1
The aim is to understand the frequency of 1 in 80213712.

Step 1:
1 can be fit into 8 8 times, resulting in a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 8.0
If we subtract 8 from 8, we get 0.
Bring next digit (0) of the dividend behind the 0 and repeat the process: 0 / 1

Let's proceed to step 2:
When dividing 0 by 1, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 80.0
If we take 0 away from 0, we end up with 0.
Include the next digit (2) from the dividend after 0, then repeat: 2 / 1

Let's proceed to step 3:
If we divide 2 by 1, we get 2 and a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 802.0
Subtract 2 from 2 to get 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 1

Going ahead to step 4:
If we divide 1 by 1, we get 1 and a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 8021.0
The remainder is 0 after subtracting 1 from 1.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 1

Step 5:
1 goes into 3 3 times with a remainder of 0.
The next digit of our result is 3. 
Result so far: 80213.0
Deduct 3 from 3 and we're left with 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 1

Step 6:
If we divide 7 by 1, we get 7 and a remainder of 0.
Put 7 as the next digit of the answer. 
Result so far: 802137.0
If we subtract 7 from 7, we get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 1

Let's proceed to step 7:
The number 1 fits into 1 1 times, leaving a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 8021371.0
The remainder is 0 after subtracting 1 from 1.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 1

Let's proceed to step 8:
1 goes into 2 2 times with a remainder of 0.
Record the quotient 2 as the next digit in the result. 
Result so far: 80213712.0
If we take 2 away from 2, we end up 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.

Moving on to step 9:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 80213712.0
Subtracting 0 from 0 leaves us 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.

Step 10:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 80213712.0
If we take 0 away from 0, we end up 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.

In conclusion, the division gives 80213712.0 with a balance of 0.0.
