We divide 486142 by 1
Our goal is to divide 486142 by 1.

Advancing to step 1:
4 divided by 1 is 4 with a remainder of 0.
Put 4 as the next digit of the answer. 
Result so far: 4.0
Subtracting 4 from 4 leaves us with 0.
Append the next digit (8) from the dividend to 0 and continue with: 8 / 1

On to step 2:
8 divided by 1 is 8 with a remainder of 0.
Use 8 as the next digit of our solution. 
Result so far: 48.0
Subtracting 8 from 8 leaves us with 0.
Take the next digit (6) from the dividend and append it to 0, then repeat: 6 / 1

Going ahead to step 3:
When dividing 6 by 1, we get 6 with a remainder of 0.
Record the quotient 6 as the next digit in the result. 
Result so far: 486.0
Subtract 6 from 6 to get 0.
Include the next digit (1) from the dividend after 0, then repeat: 1 / 1

Let's proceed to step 4:
When dividing 1 by 1, we get 1 with a remainder of 0.
The number 1 becomes the next digit in our result. 
Result so far: 4861.0
If we subtract 1 from 1, we get 0.
Take the next digit (4) from the dividend and append it to 0, then repeat: 4 / 1

Moving on to step 5:
4 divided by 1 is 4 with a remainder of 0.
The number 4 becomes the next digit in our result. 
Result so far: 48614.0
Subtract 4 from 4 to get 0.
Grab the next digit (2) from the dividend, add it to 0, then carry on: 2 / 1

Moving on to step 6:
If we divide 2 by 1, we get 2 and a remainder of 0.
Use 2 as the next digit of our solution. 
Result so far: 486142.0
The remainder is 0 after subtracting 2 from 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Step 7:
When dividing 0 by 1, we get 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 486142.0
Subtract 0 from 0 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.

Let's proceed to step 8:
When dividing 0 by 1, we get 0 with a remainder of 0.
Put 0 as the next digit of the answer. 
Result so far: 486142.0
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.

Our division results in 486142.0 with a remaining 0.0.
