We look at the division of 394579 by 10 
We want to divide 394579 by 10.

Step 1:
If we divide 3 by 10, we get 0 and a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 10

Step 2:
The number 10 fits into 39 3 times, leaving a remainder of 9.
Record the quotient 3 as the next digit in the result. 
Result so far: 3.0
If we subtract 30 from 39, we get 9.
Bring next digit (4) of the dividend behind the 9 and repeat the process: 94 / 10

Step 3:
10 can be fit into 94 9 times, resulting in a remainder of 4.
Put 9 as the next digit of the answer. 
Result so far: 39.0
If we take 90 away from 94, we end up with 4.
Grab the next digit (5) from the dividend, add it to 4, then carry on: 45 / 10

Let's proceed to step 4:
10 goes into 45 4 times with a remainder of 5.
Write down 4 as next digit of the result. 
Result so far: 394.0
If we take 40 away from 45, we end up with 5.
Append the next digit (7) from the dividend to 5 and continue with: 57 / 10

Step 5:
10 goes into 57 5 times with a remainder of 7.
Put 5 as the next digit of the answer. 
Result so far: 3945.0
The remainder is 7 after subtracting 50 from 57.
Bring next digit (9) of the dividend behind the 7 and repeat the process: 79 / 10

Let's proceed to step 6:
When dividing 79 by 10, we get 7 with a remainder of 9.
The next digit of our result is 7. 
Result so far: 39457.0
The remainder is 9 after subtracting 70 from 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Going ahead to step 7:
90 divided by 10 is 9 with a remainder of 0.
The number 9 becomes the next digit in our result. 
Result so far: 39457.9
The remainder is 0 after subtracting 90 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 0, and continue the process.

Moving on to step 8:
0 divided by 10 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 39457.9
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.

Step 9:
0 divided by 10 is 0 with a remainder of 0.
Use 0 as the next digit of our solution. 
Result so far: 39457.9
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.

After the division, we end up with 39457.9 and a remainder of 0.0.
