We're dividing 390331 by 99 
We want to divide 390331 by 99.

Moving on to step 1:
99 goes into 3 0 times with a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Include the next digit (9) from the dividend after 3, then repeat: 39 / 99

Let's proceed to step 2:
The number 99 fits into 39 0 times, leaving a remainder of 39.
The next digit of our result is 0. 
Result so far: 0.0
Subtracting 0 from 39 leaves us with 39.
Bring next digit (0) of the dividend behind the 39 and repeat the process: 390 / 99

Step 3:
The number 99 fits into 390 3 times, leaving a remainder of 93.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 297 from 390 and we're left with 93.
Include the next digit (3) from the dividend after 93, then repeat: 933 / 99

On to step 4:
99 can be fit into 933 9 times, resulting in a remainder of 42.
Record the quotient 9 as the next digit in the result. 
Result so far: 39.0
If we subtract 891 from 933, we get 42.
Take the next digit (3) from the dividend and append it to 42, then repeat: 423 / 99

Let's proceed to step 5:
99 goes into 423 4 times with a remainder of 27.
The number 4 becomes the next digit in our result. 
Result so far: 394.0
Subtract 396 from 423 to get 27.
Grab the next digit (1) from the dividend, add it to 27, then carry on: 271 / 99

On to step 6:
The number 99 fits into 271 2 times, leaving a remainder of 73.
Put 2 as the next digit of the answer. 
Result so far: 3942.0
If we subtract 198 from 271, we get 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Advancing to step 7:
If we divide 730 by 99, we get 7 and a remainder of 37.
Put 7 as the next digit of the answer. 
Result so far: 3942.7
Deduct 693 from 730 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Moving on to step 8:
370 divided by 99 is 3 with a remainder of 73.
Record the quotient 3 as the next digit in the result. 
Result so far: 3942.73
If we take 297 away from 370, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Step 9:
99 goes into 730 7 times with a remainder of 37.
The next digit of our result is 7. 
Result so far: 3942.737
Deduct 693 from 730 and we're left with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Advancing to step 10:
If we divide 370 by 99, we get 3 and a remainder of 73.
Use 3 as the next digit of our solution. 
Result so far: 3942.7373
Subtracting 297 from 370 leaves us with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Moving on to step 11:
99 can be fit into 730 7 times, resulting in a remainder of 37.
The next digit of our result is 7. 
Result so far: 3942.73737
If we subtract 693 from 730, we get 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Let's proceed to step 12:
If we divide 370 by 99, we get 3 and a remainder of 73.
Write down 3 as next digit of the result. 
Result so far: 3942.737373
If we take 297 away from 370, we end up with 73.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

Let's proceed to step 13:
99 goes into 730 7 times with a remainder of 37.
Use 7 as the next digit of our solution. 
Result so far: 3942.7373737
If we take 693 away from 730, we end up with 37.
Since there are no more digits in the dividend, we add a zero to the remainder making it 370, and continue the process.

Step 14:
99 can be fit into 370 3 times, resulting in a remainder of 73.
The next digit of our result is 3. 
Result so far: 3942.73737373
The remainder is 73 after subtracting 297 from 370.
Since there are no more digits in the dividend, we add a zero to the remainder making it 730, and continue the process.

The quotient of the division is 3942.73737373, and the remainder is 7.3e-08.
