We're dividing 143054 by 1 
The aim is to understand the frequency of 1 in 143054.

Advancing to step 1:
1 divided by 1 is 1 with a remainder of 0.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 1 from 1 and we're left with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 1

Moving on to step 2:
When dividing 4 by 1, we get 4 with a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 14.0
If we subtract 4 from 4, we get 0.
Fetch the next digit (3) from the dividend, attach it to 0 and continue: 3 / 1

Step 3:
When dividing 3 by 1, we get 3 with a remainder of 0.
Record the quotient 3 as the next digit in the result. 
Result so far: 143.0
Subtract 3 from 3 to get 0.
Grab the next digit (0) from the dividend, add it to 0, then carry on: 0 / 1

Step 4:
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: 1430.0
The remainder is 0 after subtracting 0 from 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 1

Going ahead to step 5:
1 goes into 5 5 times with a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 14305.0
If we subtract 5 from 5, we get 0.
Grab the next digit (4) from the dividend, add it to 0, then carry on: 4 / 1

Advancing to step 6:
1 goes into 4 4 times with a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 143054.0
Deduct 4 from 4 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 7:
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: 143054.0
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.

Let's proceed to step 8:
If we divide 0 by 1, we get 0 and a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 143054.0
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.

After the division, we end up with 143054.0 and a remainder of 0.0.
