We look at the division of 398330 by 99 
We want to figure out the number of times 398330 can be divided by 99.

Going ahead to step 1:
99 can be fit into 3 0 times, resulting in a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 3, we end up with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 99

Advancing to step 2:
99 can be fit into 39 0 times, resulting in a remainder of 39.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Fetch the next digit (8) from the dividend, attach it to 39 and continue: 398 / 99

Moving on to step 3:
99 goes into 398 4 times with a remainder of 2.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
Subtract 396 from 398 to get 2.
Append the next digit (3) from the dividend to 2 and continue with: 23 / 99

Going ahead to step 4:
99 can be fit into 23 0 times, resulting in a remainder of 23.
The next digit of our result is 0. 
Result so far: 40.0
Subtract 0 from 23 to get 23.
Include the next digit (3) from the dividend after 23, then repeat: 233 / 99

Advancing to step 5:
99 goes into 233 2 times with a remainder of 35.
Put 2 as the next digit of the answer. 
Result so far: 402.0
Subtract 198 from 233 to get 35.
Grab the next digit (0) from the dividend, add it to 35, then carry on: 350 / 99

Advancing to step 6:
99 goes into 350 3 times with a remainder of 53.
Use 3 as the next digit of our solution. 
Result so far: 4023.0
Subtracting 297 from 350 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 7:
When dividing 530 by 99, we get 5 with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 4023.5
Subtract 495 from 530 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Going ahead to step 8:
99 can be fit into 350 3 times, resulting in a remainder of 53.
Write down 3 as next digit of the result. 
Result so far: 4023.53
The remainder is 53 after subtracting 297 from 350.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 9:
The number 99 fits into 530 5 times, leaving a remainder of 35.
Record the quotient 5 as the next digit in the result. 
Result so far: 4023.535
Deduct 495 from 530 and we're left with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 10:
99 can be fit into 350 3 times, resulting in a remainder of 53.
Use 3 as the next digit of our solution. 
Result so far: 4023.5353
If we take 297 away from 350, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Moving on to step 11:
99 can be fit into 530 5 times, resulting in a remainder of 35.
Put 5 as the next digit of the answer. 
Result so far: 4023.53535
Subtract 495 from 530 to get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 12:
If we divide 350 by 99, we get 3 and a remainder of 53.
Record the quotient 3 as the next digit in the result. 
Result so far: 4023.535353
If we take 297 away from 350, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Going ahead to step 13:
99 goes into 530 5 times with a remainder of 35.
Use 5 as the next digit of our solution. 
Result so far: 4023.5353535
If we subtract 495 from 530, we get 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

Moving on to step 14:
If we divide 350 by 99, we get 3 and a remainder of 53.
The next digit of our result is 3. 
Result so far: 4023.53535353
If we take 297 away from 350, we end up with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

In conclusion, the division gives 4023.53535353 with a balance of 5.3e-08.
