57420 ÷ 1 
We're looking to find how many times 1 goes into 57420.

Step 1:
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: 5.0
Subtract 5 from 5 to get 0.
Include the next digit (7) from the dividend after 0, then repeat: 7 / 1

On to step 2:
If we divide 7 by 1, we get 7 and a remainder of 0.
The next digit of our result is 7. 
Result so far: 57.0
If we subtract 7 from 7, we get 0.
Include the next digit (4) from the dividend after 0, then repeat: 4 / 1

Advancing to step 3:
If we divide 4 by 1, we get 4 and a remainder of 0.
Use 4 as the next digit of our solution. 
Result so far: 574.0
Subtracting 4 from 4 leaves us with 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 1

Let's proceed to step 4:
1 goes into 2 2 times with a remainder of 0.
Write down 2 as next digit of the result. 
Result so far: 5742.0
The remainder is 0 after subtracting 2 from 2.
Fetch the next digit (0) from the dividend, attach it to 0 and continue: 0 / 1

Moving on to step 5:
0 divided by 1 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 57420.0
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.

Step 6:
1 can be fit into 0 0 times, resulting in a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 57420.0
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.

On to step 7:
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: 57420.0
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 result is 57420.0 with a remainder of 0.0.
