We divide 1204644 by 1
The aim is to understand the frequency of 1 in 1204644.

Step 1:
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: 1.0
Subtracting 1 from 1 leaves us with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 1

Advancing to step 2:
1 can be fit into 2 2 times, resulting in a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 12.0
Deduct 2 from 2 and we're left with 0.
Append the next digit (0) from the dividend to 0 and continue with: 0 / 1

Advancing to step 3:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 120.0
Subtract 0 from 0 to get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 1

Let's proceed to step 4:
When dividing 4 by 1, we get 4 with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 1204.0
Subtracting 4 from 4 leaves us with 0.
Append the next digit (6) from the dividend to 0 and continue with: 6 / 1

On to step 5:
If we divide 6 by 1, we get 6 and a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 12046.0
If we take 6 away from 6, we end up with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 1

Advancing to step 6:
1 goes into 4 4 times with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 120464.0
If we subtract 4 from 4, we get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Let's proceed to step 7:
1 goes into 4 4 times with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 1204644.0
Subtract 4 from 4 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.

On to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 1204644.0
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.

On to step 9:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 1204644.0
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.

In conclusion, the division gives 1204644.0 with a balance of 0.0.
