349640 ÷ 99 
We're looking to find how many times 99 goes into 349640.

On to step 1:
3 divided by 99 is 0 with a remainder of 3.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 3, we get 3.
Append the next digit (4) from the dividend to 3 and continue with: 34 / 99

Step 2:
When dividing 34 by 99, we get 0 with a remainder of 34.
The next digit of our result is 0. 
Result so far: 0.0
If we subtract 0 from 34, we get 34.
Include the next digit (9) from the dividend after 34, then repeat: 349 / 99

Advancing to step 3:
The number 99 fits into 349 3 times, leaving a remainder of 52.
The next digit of our result is 3. 
Result so far: 3.0
Deduct 297 from 349 and we're left with 52.
Bring next digit (6) of the dividend behind the 52 and repeat the process: 526 / 99

On to step 4:
If we divide 526 by 99, we get 5 and a remainder of 31.
The next digit of our result is 5. 
Result so far: 35.0
If we take 495 away from 526, we end up with 31.
Include the next digit (4) from the dividend after 31, then repeat: 314 / 99

Step 5:
If we divide 314 by 99, we get 3 and a remainder of 17.
Put 3 as the next digit of the answer. 
Result so far: 353.0
Deduct 297 from 314 and we're left with 17.
Include the next digit (0) from the dividend after 17, then repeat: 170 / 99

Let's proceed to step 6:
When dividing 170 by 99, we get 1 with a remainder of 71.
Use 1 as the next digit of our solution. 
Result so far: 3531.0
Subtracting 99 from 170 leaves us 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.

Step 7:
99 goes into 710 7 times with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 3531.7
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.

On to step 8:
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: 3531.71
Subtracting 99 from 170 leaves us 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.

Advancing to step 9:
710 divided by 99 is 7 with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 3531.717
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.

Advancing to step 10:
99 goes into 170 1 times with a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 3531.7171
Subtracting 99 from 170 leaves us 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.

Moving on to step 11:
99 goes into 710 7 times with a remainder of 17.
The number 7 becomes the next digit in our result. 
Result so far: 3531.71717
Subtracting 693 from 710 leaves us 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.

Going ahead to step 12:
When dividing 170 by 99, we get 1 with a remainder of 71.
The next digit of our result is 1. 
Result so far: 3531.717171
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.

On to step 13:
The number 99 fits into 710 7 times, leaving a remainder of 17.
The next digit of our result is 7. 
Result so far: 3531.7171717
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.

Moving on to step 14:
170 divided by 99 is 1 with a remainder of 71.
Put 1 as the next digit of the answer. 
Result so far: 3531.71717171
Subtracting 99 from 170 leaves us 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.

After the division, we end up with 3531.71717171 and a remainder of 7.1e-08.
