We look at the division of 390107 by 99 
Let's see how many times 99 fits into 390107.

Advancing to step 1:
The number 99 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
Subtract 0 from 3 to get 3.
Grab the next digit (9) from the dividend, add it to 3, then carry on: 39 / 99

Let's proceed to step 2:
When dividing 39 by 99, we get 0 with a remainder of 39.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 39 and we're left with 39.
Grab the next digit (0) from the dividend, add it to 39, then carry on: 390 / 99

Let's proceed to step 3:
If we divide 390 by 99, we get 3 and a remainder of 93.
The next digit of our result is 3. 
Result so far: 3.0
The remainder is 93 after subtracting 297 from 390.
Bring next digit (1) of the dividend behind the 93 and repeat the process: 931 / 99

On to step 4:
99 can be fit into 931 9 times, resulting in a remainder of 40.
Use 9 as the next digit of our solution. 
Result so far: 39.0
If we subtract 891 from 931, we get 40.
Append the next digit (0) from the dividend to 40 and continue with: 400 / 99

Step 5:
99 goes into 400 4 times with a remainder of 4.
The next digit of our result is 4. 
Result so far: 394.0
If we subtract 396 from 400, we get 4.
Bring next digit (7) of the dividend behind the 4 and repeat the process: 47 / 99

On to step 6:
When dividing 47 by 99, we get 0 with a remainder of 47.
The next digit of our result is 0. 
Result so far: 3940.0
Deduct 0 from 47 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Step 7:
The number 99 fits into 470 4 times, leaving a remainder of 74.
Use 4 as the next digit of our solution. 
Result so far: 3940.4
Subtract 396 from 470 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 8:
740 divided by 99 is 7 with a remainder of 47.
Write down 7 as next digit of the result. 
Result so far: 3940.47
The remainder is 47 after subtracting 693 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 9:
The number 99 fits into 470 4 times, leaving a remainder of 74.
Write down 4 as next digit of the result. 
Result so far: 3940.474
Deduct 396 from 470 and we're left with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Moving on to step 10:
The number 99 fits into 740 7 times, leaving a remainder of 47.
Write down 7 as next digit of the result. 
Result so far: 3940.4747
The remainder is 47 after subtracting 693 from 740.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

Going ahead to step 11:
When dividing 470 by 99, we get 4 with a remainder of 74.
Write down 4 as next digit of the result. 
Result so far: 3940.47474
If we take 396 away from 470, we end up with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 12:
99 goes into 740 7 times with a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 3940.474747
Deduct 693 from 740 and we're left with 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

On to step 13:
When dividing 470 by 99, we get 4 with a remainder of 74.
Record the quotient 4 as the next digit in the result. 
Result so far: 3940.4747474
The remainder is 74 after subtracting 396 from 470.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Going ahead to step 14:
When dividing 740 by 99, we get 7 with a remainder of 47.
Record the quotient 7 as the next digit in the result. 
Result so far: 3940.47474747
If we subtract 693 from 740, we get 47.
Since there are no more digits in the dividend, we add a zero to the remainder making it 470, and continue the process.

After the division, we end up with 3940.47474747 and a remainder of 4.7e-08.
