We look at the division of 454445 by 1 
Our goal is to divide 454445 by 1.

Step 1:
The number 1 fits into 4 4 times, leaving a remainder of 0.
The next digit of our result is 4. 
Result so far: 4.0
Subtracting 4 from 4 leaves us with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 1

Moving on to step 2:
1 goes into 5 5 times with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 45.0
Subtracting 5 from 5 leaves us with 0.
Bring next digit (4) of the dividend behind the 0 and repeat the process: 4 / 1

Step 3:
The number 1 fits into 4 4 times, leaving a remainder of 0.
Record the quotient 4 as the next digit in the result. 
Result so far: 454.0
Deduct 4 from 4 and we're left with 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 1

Step 4:
1 can be fit into 4 4 times, resulting in a remainder of 0.
Write down 4 as next digit of the result. 
Result so far: 4544.0
Subtract 4 from 4 to get 0.
Fetch the next digit (4) from the dividend, attach it to 0 and continue: 4 / 1

Step 5:
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: 45444.0
Subtracting 4 from 4 leaves us with 0.
Take the next digit (5) from the dividend and append it to 0, then repeat: 5 / 1

Moving on to step 6:
The number 1 fits into 5 5 times, leaving a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 454445.0
The remainder is 0 after subtracting 5 from 5.
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:
The number 1 fits into 0 0 times, leaving a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 454445.0
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.

Step 8:
0 divided by 1 is 0 with a remainder of 0.
The next digit of our result is 0. 
Result so far: 454445.0
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 outcome is 454445.0, with a leftover of 0.0.
