We divide 811210 by 1
The aim is to understand the frequency of 1 in 811210.

Going ahead to step 1:
8 divided by 1 is 8 with a remainder of 0.
Put 8 as the next digit of the answer. 
Result so far: 8.0
Deduct 8 from 8 and we're left with 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

Advancing to step 2:
1 divided by 1 is 1 with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 81.0
If we take 1 away from 1, we end up with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 1

Let's proceed to step 3:
1 can be fit into 1 1 times, resulting in a remainder of 0.
Use 1 as the next digit of our solution. 
Result so far: 811.0
If we subtract 1 from 1, we get 0.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 1

Advancing to step 4:
1 can be fit into 2 2 times, resulting in a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 8112.0
If we subtract 2 from 2, we get 0.
Bring next digit (1) of the dividend behind the 0 and repeat the process: 1 / 1

Moving on to step 5:
1 goes into 1 1 times with a remainder of 0.
The next digit of our result is 1. 
Result so far: 81121.0
Deduct 1 from 1 and we're left with 0.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

On to step 6:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 811210.0
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.

Going ahead to step 7:
1 can be fit into 0 0 times, resulting in a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 811210.0
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.

Going ahead to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 811210.0
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.

After the division, we end up with 811210.0 and a remainder of 0.0.
