We look at the division of 390310 by 46 
Our goal is to divide 390310 by 46.

Step 1:
3 divided by 46 is 0 with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Bring next digit (9) of the dividend behind the 3 and repeat the process: 39 / 46

Let's proceed to step 2:
If we divide 39 by 46, we get 0 and a remainder of 39.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 39 after subtracting 0 from 39.
Fetch the next digit (0) from the dividend, attach it to 39 and continue: 390 / 46

Step 3:
46 can be fit into 390 8 times, resulting in a remainder of 22.
Use 8 as the next digit of our solution. 
Result so far: 8.0
Subtracting 368 from 390 leaves us with 22.
Bring next digit (3) of the dividend behind the 22 and repeat the process: 223 / 46

Going ahead to step 4:
If we divide 223 by 46, we get 4 and a remainder of 39.
Record the quotient 4 as the next digit in the result. 
Result so far: 84.0
If we subtract 184 from 223, we get 39.
Bring next digit (1) of the dividend behind the 39 and repeat the process: 391 / 46

Advancing to step 5:
If we divide 391 by 46, we get 8 and a remainder of 23.
The next digit of our result is 8. 
Result so far: 848.0
The remainder is 23 after subtracting 368 from 391.
Fetch the next digit (0) from the dividend, attach it to 23 and continue: 230 / 46

On to step 6:
46 goes into 230 5 times with a remainder of 0.
Put 5 as the next digit of the answer. 
Result so far: 8485.0
Deduct 230 from 230 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.

Advancing to step 7:
0 divided by 46 is 0 with a remainder of 0.
Write down 0 as next digit of the result. 
Result so far: 8485.0
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.

Going ahead to step 8:
When dividing 0 by 46, we get 0 with a remainder of 0.
The number 0 becomes the next digit in our result. 
Result so far: 8485.0
Deduct 0 from 0 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.

The quotient of the division is 8485.0, and the remainder is 0.0.
