We're dividing 54343625 by 1 
The aim is to understand the frequency of 1 in 54343625.

Let's proceed to step 1:
1 goes into 5 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 5.0
Deduct 5 from 5 and we're left with 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 1

Advancing to step 2:
The number 1 fits into 4 4 times, leaving a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 54.0
The remainder is 0 after subtracting 4 from 4.
Bring next digit (3) of the dividend behind the 0 and repeat the process: 3 / 1

Advancing to step 3:
If we divide 3 by 1, we get 3 and a remainder of 0.
Use 3 as the next digit of our solution. 
Result so far: 543.0
Subtract 3 from 3 to get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 1

Advancing to step 4:
1 can be fit into 4 4 times, resulting in a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 5434.0
If we take 4 away from 4, we end up with 0.
Append the next digit (3) from the dividend to 0 and continue with: 3 / 1

Moving on to step 5:
When dividing 3 by 1, we get 3 with a remainder of 0.
Write down 3 as next digit of the result. 
Result so far: 54343.0
Deduct 3 from 3 and we're left with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 1

Step 6:
When dividing 6 by 1, we get 6 with a remainder of 0.
Use 6 as the next digit of our solution. 
Result so far: 543436.0
If we take 6 away from 6, we end up with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 1

Step 7:
If we divide 2 by 1, we get 2 and a remainder of 0.
The number 2 becomes the next digit in our result. 
Result so far: 5434362.0
Deduct 2 from 2 and we're left with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 1

On to step 8:
1 goes into 5 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 54343625.0
Subtract 5 from 5 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 9:
1 goes into 0 0 times with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 54343625.0
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.

Going ahead to step 10:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 54343625.0
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.

The final result is 54343625.0 with a remainder of 0.0.
