Let's divide 457572 by 1
We want to figure out the number of times 457572 can be divided by 1.

Step 1:
When dividing 4 by 1, we get 4 with a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 4.0
Deduct 4 from 4 and we're left with 0.
Bring next digit (5) of the dividend behind the 0 and repeat the process: 5 / 1

Moving on to step 2:
1 can be fit into 5 5 times, resulting in a remainder of 0.
Record the quotient 5 as the next digit in the result. 
Result so far: 45.0
Deduct 5 from 5 and we're left with 0.
Append the next digit (7) from the dividend to 0 and continue with: 7 / 1

Step 3:
If we divide 7 by 1, we get 7 and a remainder of 0.
The number 7 becomes the next digit in our result. 
Result so far: 457.0
Subtracting 7 from 7 leaves us with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 1

Advancing to step 4:
When dividing 5 by 1, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 4575.0
Subtract 5 from 5 to get 0.
Bring next digit (7) of the dividend behind the 0 and repeat the process: 7 / 1

Let's proceed to step 5:
The number 1 fits into 7 7 times, leaving a remainder of 0.
The next digit of our result is 7. 
Result so far: 45757.0
Subtract 7 from 7 to get 0.
Fetch the next digit (2) from the dividend, attach it to 0 and continue: 2 / 1

Let's proceed to step 6:
2 divided by 1 is 2 with a remainder of 0.
The next digit of our result is 2. 
Result so far: 457572.0
Subtract 2 from 2 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 7:
1 goes into 0 0 times with a remainder of 0.
The next digit of our result is 0. 
Result so far: 457572.0
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.

Advancing to step 8:
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: 457572.0
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.

The final result is 457572.0 with a remainder of 0.0.
