We look at the division of 652111 by 1 
The aim is to understand the frequency of 1 in 652111.

Advancing to step 1:
If we divide 6 by 1, we get 6 and a remainder of 0.
The next digit of our result is 6. 
Result so far: 6.0
If we subtract 6 from 6, we get 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 1

Step 2:
1 can be fit into 5 5 times, resulting in a remainder of 0.
Use 5 as the next digit of our solution. 
Result so far: 65.0
The remainder is 0 after subtracting 5 from 5.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 1

Step 3:
If we divide 2 by 1, we get 2 and a remainder of 0.
The next digit of our result is 2. 
Result so far: 652.0
Deduct 2 from 2 and we're left with 0.
Append the next digit (1) from the dividend to 0 and continue with: 1 / 1

On to step 4:
1 can be fit into 1 1 times, resulting in a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 6521.0
Subtracting 1 from 1 leaves us with 0.
Grab the next digit (1) from the dividend, add it to 0, then carry on: 1 / 1

Going ahead to step 5:
1 goes into 1 1 times with a remainder of 0.
Record the quotient 1 as the next digit in the result. 
Result so far: 65211.0
Deduct 1 from 1 and we're left with 0.
Fetch the next digit (1) from the dividend, attach it to 0 and continue: 1 / 1

Going ahead to step 6:
The number 1 fits into 1 1 times, leaving a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 652111.0
Subtract 1 from 1 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.

Advancing to step 7:
0 divided by 1 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 652111.0
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.

Step 8:
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: 652111.0
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.

The final outcome is 652111.0, with a leftover of 0.0.
