390550 ÷ 10 
Our goal is to divide 390550 by 10.

Going ahead to step 1:
The number 10 fits into 3 0 times, leaving a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 10

Let's proceed to step 2:
If we divide 39 by 10, we get 3 and a remainder of 9.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtracting 30 from 39 leaves us with 9.
Include the next digit (0) from the dividend after 9, then repeat: 90 / 10

Advancing to step 3:
The number 10 fits into 90 9 times, leaving a remainder of 0.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
If we take 90 away from 90, we end up with 0.
Grab the next digit (5) from the dividend, add it to 0, then carry on: 5 / 10

Going ahead to step 4:
10 goes into 5 0 times with a remainder of 5.
Write down 0 as next digit of the result. 
Result so far: 390.0
Deduct 0 from 5 and we're left with 5.
Bring next digit (5) of the dividend behind the 5 and repeat the process: 55 / 10

Going ahead to step 5:
When dividing 55 by 10, we get 5 with a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 3905.0
Subtracting 50 from 55 leaves us with 5.
Bring next digit (0) of the dividend behind the 5 and repeat the process: 50 / 10

Going ahead to step 6:
When dividing 50 by 10, we get 5 with a remainder of 0.
Write down 5 as next digit of the result. 
Result so far: 39055.0
Deduct 50 from 50 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.

Let's proceed to step 7:
10 goes into 0 0 times with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 39055.0
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:
0 divided by 10 is 0 with a remainder of 0.
Record the quotient 0 as the next digit in the result. 
Result so far: 39055.0
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 39055.0 with a remaining 0.0.
