We're dividing 399285 by 99 
Our goal is to divide 399285 by 99.

Going ahead 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
Subtracting 0 from 3 leaves us with 3.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 99

Let's proceed to step 2:
39 divided by 99 is 0 with 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.
Take the next digit (9) from the dividend and append it to 39, then repeat: 399 / 99

Let's proceed to step 3:
99 can be fit into 399 4 times, resulting in a remainder of 3.
Record the quotient 4 as the next digit in the result. 
Result so far: 4.0
Subtracting 396 from 399 leaves us with 3.
Fetch the next digit (2) from the dividend, attach it to 3 and continue: 32 / 99

Step 4:
If we divide 32 by 99, we get 0 and a remainder of 32.
The number 0 becomes the next digit in our result. 
Result so far: 40.0
Subtract 0 from 32 to get 32.
Append the next digit (8) from the dividend to 32 and continue with: 328 / 99

Step 5:
When dividing 328 by 99, we get 3 with a remainder of 31.
The number 3 becomes the next digit in our result. 
Result so far: 403.0
If we take 297 away from 328, we end up with 31.
Include the next digit (5) from the dividend after 31, then repeat: 315 / 99

Step 6:
315 divided by 99 is 3 with a remainder of 18.
Write down 3 as next digit of the result. 
Result so far: 4033.0
Subtracting 297 from 315 leaves us with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 7:
When dividing 180 by 99, we get 1 with a remainder of 81.
The next digit of our result is 1. 
Result so far: 4033.1
Subtracting 99 from 180 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Let's proceed to step 8:
If we divide 810 by 99, we get 8 and a remainder of 18.
Record the quotient 8 as the next digit in the result. 
Result so far: 4033.18
If we take 792 away from 810, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 9:
The number 99 fits into 180 1 times, leaving a remainder of 81.
Write down 1 as next digit of the result. 
Result so far: 4033.181
If we subtract 99 from 180, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 10:
810 divided by 99 is 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 4033.1818
If we subtract 792 from 810, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

On to step 11:
When dividing 180 by 99, we get 1 with a remainder of 81.
Put 1 as the next digit of the answer. 
Result so far: 4033.18181
If we subtract 99 from 180, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Step 12:
When dividing 810 by 99, we get 8 with a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 4033.181818
Deduct 792 from 810 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 13:
99 goes into 180 1 times with a remainder of 81.
The number 1 becomes the next digit in our result. 
Result so far: 4033.1818181
If we subtract 99 from 180, we get 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 14:
810 divided by 99 is 8 with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 4033.18181818
If we subtract 792 from 810, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

The final result is 4033.18181818 with a remainder of 1.8e-08.
