We look at the division of 642464 by 1 
The aim is to understand the frequency of 1 in 642464.

Let's proceed to step 1:
1 can be fit into 6 6 times, resulting in a remainder of 0.
The next digit of our result is 6. 
Result so far: 6.0
If we take 6 away from 6, we end up with 0.
Append the next digit (4) from the dividend to 0 and continue with: 4 / 1

Let's proceed to step 2:
When dividing 4 by 1, we get 4 with a remainder of 0.
The next digit of our result is 4. 
Result so far: 64.0
The remainder is 0 after subtracting 4 from 4.
Bring next digit (2) of the dividend behind the 0 and repeat the process: 2 / 1

Moving on to step 3:
1 goes into 2 2 times with a remainder of 0.
Put 2 as the next digit of the answer. 
Result so far: 642.0
Deduct 2 from 2 and we're left with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 1

On to step 4:
The number 1 fits into 4 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 6424.0
Subtracting 4 from 4 leaves us with 0.
Fetch the next digit (6) from the dividend, attach it to 0 and continue: 6 / 1

Going ahead to step 5:
If we divide 6 by 1, we get 6 and a remainder of 0.
The number 6 becomes the next digit in our result. 
Result so far: 64246.0
If we take 6 away from 6, we end up with 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Step 6:
1 goes into 4 4 times with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 642464.0
If we take 4 away from 4, 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.

Going ahead to step 7:
0 divided by 1 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 642464.0
Deduct 0 from 0 and we're left 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.

Let's proceed to 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: 642464.0
The remainder is 0 after subtracting 0 from 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 642464.0 and a remainder of 0.0.
