Let's divide 403838 by 99
Our goal is to divide 403838 by 99.

Advancing to step 1:
99 can be fit into 4 0 times, resulting in a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 4, we get 4.
Append the next digit (0) from the dividend to 4 and continue with: 40 / 99

Let's proceed to step 2:
40 divided by 99 is 0 with a remainder of 40.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Deduct 0 from 40 and we're left with 40.
Fetch the next digit (3) from the dividend, attach it to 40 and continue: 403 / 99

Advancing to step 3:
99 goes into 403 4 times with a remainder of 7.
The next digit of our result is 4. 
Result so far: 4.0
The remainder is 7 after subtracting 396 from 403.
Include the next digit (8) from the dividend after 7, then repeat: 78 / 99

Moving on to step 4:
The number 99 fits into 78 0 times, leaving a remainder of 78.
The next digit of our result is 0. 
Result so far: 40.0
Subtract 0 from 78 to get 78.
Include the next digit (3) from the dividend after 78, then repeat: 783 / 99

On to step 5:
783 divided by 99 is 7 with a remainder of 90.
The next digit of our result is 7. 
Result so far: 407.0
If we take 693 away from 783, we end up with 90.
Include the next digit (8) from the dividend after 90, then repeat: 908 / 99

On to step 6:
908 divided by 99 is 9 with a remainder of 17.
Put 9 as the next digit of the answer. 
Result so far: 4079.0
Subtract 891 from 908 to get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Moving on to step 7:
99 can be fit into 170 1 times, resulting in a remainder of 71.
Put 1 as the next digit of the answer. 
Result so far: 4079.1
Subtract 99 from 170 to get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Let's proceed to step 8:
If we divide 710 by 99, we get 7 and a remainder of 17.
The next digit of our result is 7. 
Result so far: 4079.17
Deduct 693 from 710 and we're left with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

On to step 9:
170 divided by 99 is 1 with a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 4079.171
Deduct 99 from 170 and we're left with 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 10:
The number 99 fits into 710 7 times, leaving a remainder of 17.
Record the quotient 7 as the next digit in the result. 
Result so far: 4079.1717
The remainder is 17 after subtracting 693 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Advancing to step 11:
99 can be fit into 170 1 times, resulting in a remainder of 71.
Put 1 as the next digit of the answer. 
Result so far: 4079.17171
If we subtract 99 from 170, we get 71.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Going ahead to step 12:
When dividing 710 by 99, we get 7 with a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 4079.171717
The remainder is 17 after subtracting 693 from 710.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Let's proceed to step 13:
The number 99 fits into 170 1 times, leaving a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 4079.1717171
The remainder is 71 after subtracting 99 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 710, and continue the process.

Moving on to step 14:
99 can be fit into 710 7 times, resulting in a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 4079.17171717
If we subtract 693 from 710, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Our division results in 4079.17171717 with a remaining 1.7e-08.
