340540 ÷ 99 
Our goal is to divide 340540 by 99.

Going ahead 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
Subtract 0 from 3 to get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 99

Going ahead to step 2:
34 divided by 99 is 0 with a remainder of 34.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 34 and we're left with 34.
Bring next digit (0) of the dividend behind the 34 and repeat the process: 340 / 99

On to step 3:
The number 99 fits into 340 3 times, leaving a remainder of 43.
Use 3 as the next digit of our solution. 
Result so far: 3.0
Deduct 297 from 340 and we're left with 43.
Fetch the next digit (5) from the dividend, attach it to 43 and continue: 435 / 99

Let's proceed to step 4:
If we divide 435 by 99, we get 4 and a remainder of 39.
Use 4 as the next digit of our solution. 
Result so far: 34.0
Deduct 396 from 435 and we're left with 39.
Take the next digit (4) from the dividend and append it to 39, then repeat: 394 / 99

On to step 5:
If we divide 394 by 99, we get 3 and a remainder of 97.
The next digit of our result is 3. 
Result so far: 343.0
Subtracting 297 from 394 leaves us with 97.
Include the next digit (0) from the dividend after 97, then repeat: 970 / 99

Moving on to step 6:
99 can be fit into 970 9 times, resulting in a remainder of 79.
Put 9 as the next digit of the answer. 
Result so far: 3439.0
Deduct 891 from 970 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

On to step 7:
790 divided by 99 is 7 with a remainder of 97.
The number 7 becomes the next digit in our result. 
Result so far: 3439.7
If we subtract 693 from 790, we get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Moving on to step 8:
99 can be fit into 970 9 times, resulting in a remainder of 79.
The number 9 becomes the next digit in our result. 
Result so far: 3439.79
If we subtract 891 from 970, we get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Let's proceed to step 9:
99 goes into 790 7 times with a remainder of 97.
Put 7 as the next digit of the answer. 
Result so far: 3439.797
The remainder is 97 after subtracting 693 from 790.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

Advancing to step 10:
The number 99 fits into 970 9 times, leaving a remainder of 79.
Write down 9 as next digit of the result. 
Result so far: 3439.7979
Deduct 891 from 970 and we're left with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Moving on to step 11:
790 divided by 99 is 7 with a remainder of 97.
Record the quotient 7 as the next digit in the result. 
Result so far: 3439.79797
Subtracting 693 from 790 leaves us with 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

On to step 12:
The number 99 fits into 970 9 times, leaving a remainder of 79.
Use 9 as the next digit of our solution. 
Result so far: 3439.797979
Subtract 891 from 970 to get 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Advancing to step 13:
The number 99 fits into 790 7 times, leaving a remainder of 97.
Write down 7 as next digit of the result. 
Result so far: 3439.7979797
If we subtract 693 from 790, we get 97.
Since there are no more digits in the dividend, we add a zero to the remainder making it 970, and continue the process.

On to step 14:
970 divided by 99 is 9 with a remainder of 79.
Record the quotient 9 as the next digit in the result. 
Result so far: 3439.79797979
If we take 891 away from 970, we end up with 79.
Since there are no more digits in the dividend, we add a zero to the remainder making it 790, and continue the process.

Our division results in 3439.79797979 with a remaining 7.9e-08.
