We divide 390451 by 99
We want to divide 390451 by 99.

Moving on to step 1:
3 divided by 99 is 0 with a remainder of 3.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Take the next digit (9) from the dividend and append it to 3, then repeat: 39 / 99

Advancing to step 2:
The number 99 fits into 39 0 times, leaving a remainder of 39.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we subtract 0 from 39, we get 39.
Take the next digit (0) from the dividend and append it to 39, then repeat: 390 / 99

Advancing to step 3:
99 can be fit into 390 3 times, resulting in a remainder of 93.
Write down 3 as next digit of the result. 
Result so far: 3.0
Subtract 297 from 390 to get 93.
Bring next digit (4) of the dividend behind the 93 and repeat the process: 934 / 99

Moving on to step 4:
934 divided by 99 is 9 with a remainder of 43.
Use 9 as the next digit of our solution. 
Result so far: 39.0
Deduct 891 from 934 and we're left with 43.
Include the next digit (5) from the dividend after 43, then repeat: 435 / 99

Step 5:
If we divide 435 by 99, we get 4 and a remainder of 39.
Write down 4 as next digit of the result. 
Result so far: 394.0
Subtracting 396 from 435 leaves us with 39.
Include the next digit (1) from the dividend after 39, then repeat: 391 / 99

Let's proceed to step 6:
If we divide 391 by 99, we get 3 and a remainder of 94.
Put 3 as the next digit of the answer. 
Result so far: 3943.0
The remainder is 94 after subtracting 297 from 391.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Step 7:
When dividing 940 by 99, we get 9 with a remainder of 49.
Put 9 as the next digit of the answer. 
Result so far: 3943.9
Subtract 891 from 940 to get 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

On to step 8:
The number 99 fits into 490 4 times, leaving a remainder of 94.
The number 4 becomes the next digit in our result. 
Result so far: 3943.94
Deduct 396 from 490 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Let's proceed to step 9:
When dividing 940 by 99, we get 9 with a remainder of 49.
Use 9 as the next digit of our solution. 
Result so far: 3943.949
The remainder is 49 after subtracting 891 from 940.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Going ahead to step 10:
If we divide 490 by 99, we get 4 and a remainder of 94.
The next digit of our result is 4. 
Result so far: 3943.9494
Subtracting 396 from 490 leaves us with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

Going ahead to step 11:
99 goes into 940 9 times with a remainder of 49.
Put 9 as the next digit of the answer. 
Result so far: 3943.94949
If we take 891 away from 940, we end up with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Step 12:
99 can be fit into 490 4 times, resulting in a remainder of 94.
The number 4 becomes the next digit in our result. 
Result so far: 3943.949494
If we take 396 away from 490, we end up with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

On to step 13:
99 goes into 940 9 times with a remainder of 49.
The next digit of our result is 9. 
Result so far: 3943.9494949
Subtracting 891 from 940 leaves us with 49.
Since there are no more digits in the dividend, we add a zero to the remainder making it 490, and continue the process.

Let's proceed to step 14:
When dividing 490 by 99, we get 4 with a remainder of 94.
Use 4 as the next digit of our solution. 
Result so far: 3943.94949494
Deduct 396 from 490 and we're left with 94.
Since there are no more digits in the dividend, we add a zero to the remainder making it 940, and continue the process.

The quotient of the division is 3943.94949494, and the remainder is 9.4e-08.
