389901 ÷ 99 
We want to divide 389901 by 99.

On to step 1:
99 can be fit into 3 0 times, resulting in a remainder of 3.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 3 after subtracting 0 from 3.
Bring next digit (8) of the dividend behind the 3 and repeat the process: 38 / 99

Going ahead to step 2:
When dividing 38 by 99, we get 0 with a remainder of 38.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 38 and we're left with 38.
Bring next digit (9) of the dividend behind the 38 and repeat the process: 389 / 99

Let's proceed to step 3:
99 goes into 389 3 times with a remainder of 92.
Write down 3 as next digit of the result. 
Result so far: 3.0
The remainder is 92 after subtracting 297 from 389.
Take the next digit (9) from the dividend and append it to 92, then repeat: 929 / 99

Moving on to step 4:
929 divided by 99 is 9 with a remainder of 38.
Put 9 as the next digit of the answer. 
Result so far: 39.0
Deduct 891 from 929 and we're left with 38.
Bring next digit (0) of the dividend behind the 38 and repeat the process: 380 / 99

Going ahead to step 5:
When dividing 380 by 99, we get 3 with a remainder of 83.
Use 3 as the next digit of our solution. 
Result so far: 393.0
Deduct 297 from 380 and we're left with 83.
Bring next digit (1) of the dividend behind the 83 and repeat the process: 831 / 99

Advancing to step 6:
831 divided by 99 is 8 with a remainder of 39.
The number 8 becomes the next digit in our result. 
Result so far: 3938.0
If we take 792 away from 831, we end up with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 7:
If we divide 390 by 99, we get 3 and a remainder of 93.
Write down 3 as next digit of the result. 
Result so far: 3938.3
If we subtract 297 from 390, we get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Step 8:
If we divide 930 by 99, we get 9 and a remainder of 39.
Write down 9 as next digit of the result. 
Result so far: 3938.39
Deduct 891 from 930 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Going ahead to step 9:
The number 99 fits into 390 3 times, leaving a remainder of 93.
Record the quotient 3 as the next digit in the result. 
Result so far: 3938.393
Deduct 297 from 390 and we're left with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Moving on to step 10:
When dividing 930 by 99, we get 9 with a remainder of 39.
Put 9 as the next digit of the answer. 
Result so far: 3938.3939
The remainder is 39 after subtracting 891 from 930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 11:
390 divided by 99 is 3 with a remainder of 93.
Write down 3 as next digit of the result. 
Result so far: 3938.39393
Subtract 297 from 390 to get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Moving on to step 12:
99 goes into 930 9 times with a remainder of 39.
Write down 9 as next digit of the result. 
Result so far: 3938.393939
The remainder is 39 after subtracting 891 from 930.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

On to step 13:
390 divided by 99 is 3 with a remainder of 93.
Write down 3 as next digit of the result. 
Result so far: 3938.3939393
Subtract 297 from 390 to get 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Let's proceed to step 14:
When dividing 930 by 99, we get 9 with a remainder of 39.
Write down 9 as next digit of the result. 
Result so far: 3938.39393939
Subtract 891 from 930 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

After the division, we end up with 3938.39393939 and a remainder of 3.9e-08.
