Let's divide 350580 by 99
We want to divide 350580 by 99.

Step 1:
When dividing 3 by 99, we get 0 with a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 3 and we're left with 3.
Include the next digit (5) from the dividend after 3, then repeat: 35 / 99

Advancing to step 2:
35 divided by 99 is 0 with a remainder of 35.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 35 to get 35.
Grab the next digit (0) from the dividend, add it to 35, then carry on: 350 / 99

Moving on to step 3:
When dividing 350 by 99, we get 3 with a remainder of 53.
Write down 3 as next digit of the result. 
Result so far: 3.0
If we subtract 297 from 350, we get 53.
Append the next digit (5) from the dividend to 53 and continue with: 535 / 99

Step 4:
535 divided by 99 is 5 with a remainder of 40.
The next digit of our result is 5. 
Result so far: 35.0
If we take 495 away from 535, we end up with 40.
Take the next digit (8) from the dividend and append it to 40, then repeat: 408 / 99

Going ahead to step 5:
99 can be fit into 408 4 times, resulting in a remainder of 12.
The number 4 becomes the next digit in our result. 
Result so far: 354.0
Subtract 396 from 408 to get 12.
Bring next digit (0) of the dividend behind the 12 and repeat the process: 120 / 99

Moving on to step 6:
120 divided by 99 is 1 with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 3541.0
The remainder is 21 after subtracting 99 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Moving on to step 7:
The number 99 fits into 210 2 times, leaving a remainder of 12.
Put 2 as the next digit of the answer. 
Result so far: 3541.2
If we take 198 away from 210, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 8:
99 can be fit into 120 1 times, resulting in a remainder of 21.
The number 1 becomes the next digit in our result. 
Result so far: 3541.21
If we take 99 away from 120, we end up with 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Going ahead to step 9:
The number 99 fits into 210 2 times, leaving a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 3541.212
If we take 198 away from 210, we end up with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Moving on to step 10:
If we divide 120 by 99, we get 1 and a remainder of 21.
The next digit of our result is 1. 
Result so far: 3541.2121
Subtract 99 from 120 to get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

On to step 11:
If we divide 210 by 99, we get 2 and a remainder of 12.
The next digit of our result is 2. 
Result so far: 3541.21212
The remainder is 12 after subtracting 198 from 210.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Let's proceed to step 12:
120 divided by 99 is 1 with a remainder of 21.
Use 1 as the next digit of our solution. 
Result so far: 3541.212121
If we subtract 99 from 120, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Let's proceed to step 13:
99 can be fit into 210 2 times, resulting in a remainder of 12.
Record the quotient 2 as the next digit in the result. 
Result so far: 3541.2121212
Subtract 198 from 210 to get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Step 14:
When dividing 120 by 99, we get 1 with a remainder of 21.
Write down 1 as next digit of the result. 
Result so far: 3541.21212121
If we subtract 99 from 120, we get 21.
Since there are no more digits in the dividend, we add a zero to the remainder making it 210, and continue the process.

Our division results in 3541.21212121 with a remaining 2.1e-08.
