We look at the division of 872030 by 1 
The aim is to understand the frequency of 1 in 872030.

Going ahead to step 1:
1 can be fit into 8 8 times, resulting in a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Subtract 8 from 8 to get 0.
Grab the next digit (7) from the dividend, add it to 0, then carry on: 7 / 1

Let's proceed to step 2:
1 goes into 7 7 times with a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 87.0
If we subtract 7 from 7, we get 0.
Take the next digit (2) from the dividend and append it to 0, then repeat: 2 / 1

Moving on to step 3:
2 divided by 1 is 2 with a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 872.0
Subtracting 2 from 2 leaves us with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 1

Moving on to step 4:
If we divide 0 by 1, we get 0 and a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 8720.0
The remainder is 0 after subtracting 0 from 0.
Include the next digit (3) from the dividend after 0, then repeat: 3 / 1

Let's proceed to step 5:
3 divided by 1 is 3 with a remainder of 0.
Put 3 as the next digit of the answer. 
Result so far: 87203.0
Deduct 3 from 3 and we're left with 0.
Take the next digit (0) from the dividend and append it to 0, then repeat: 0 / 1

Let's proceed to step 6:
1 goes into 0 0 times with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 872030.0
If we subtract 0 from 0, we get 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 7:
0 divided by 1 is 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 872030.0
Subtract 0 from 0 to get 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 8:
1 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 872030.0
If we subtract 0 from 0, we get 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 final outcome is 872030.0, with a leftover of 0.0.
