Let's divide 651568 by 1
The aim is to understand the frequency of 1 in 651568.

Going ahead to step 1:
1 goes into 6 6 times with a remainder of 0.
Write down 6 as next digit of the result. 
Result so far: 6.0
The remainder is 0 after subtracting 6 from 6.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 1

Advancing to step 2:
The number 1 fits into 5 5 times, leaving a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 65.0
Subtracting 5 from 5 leaves us 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.
Write down 1 as next digit of the result. 
Result so far: 651.0
If we subtract 1 from 1, we get 0.
Append the next digit (5) from the dividend to 0 and continue with: 5 / 1

Moving on to step 4:
If we divide 5 by 1, we get 5 and a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 6515.0
Subtracting 5 from 5 leaves us with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 1

Moving on to step 5:
1 can be fit into 6 6 times, resulting in a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 65156.0
Subtracting 6 from 6 leaves us with 0.
Include the next digit (8) from the dividend after 0, then repeat: 8 / 1

Let's proceed to step 6:
8 divided by 1 is 8 with a remainder of 0.
The number 8 becomes the next digit in our result. 
Result so far: 651568.0
If we subtract 8 from 8, 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.

On to step 7:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 651568.0
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.

On to step 8:
When dividing 0 by 1, we get 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 651568.0
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 result is 651568.0 with a remainder of 0.0.
