We're dividing 429912 by 99 
We want to divide 429912 by 99.

Step 1:
4 divided by 99 is 0 with a remainder of 4.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we take 0 away from 4, we end up with 4.
Include the next digit (2) from the dividend after 4, then repeat: 42 / 99

Let's proceed to step 2:
When dividing 42 by 99, we get 0 with a remainder of 42.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 42 to get 42.
Include the next digit (9) from the dividend after 42, then repeat: 429 / 99

Advancing to step 3:
99 goes into 429 4 times with a remainder of 33.
Write down 4 as next digit of the result. 
Result so far: 4.0
Subtracting 396 from 429 leaves us with 33.
Bring next digit (9) of the dividend behind the 33 and repeat the process: 339 / 99

Step 4:
99 goes into 339 3 times with a remainder of 42.
Put 3 as the next digit of the answer. 
Result so far: 43.0
The remainder is 42 after subtracting 297 from 339.
Fetch the next digit (1) from the dividend, attach it to 42 and continue: 421 / 99

On to step 5:
If we divide 421 by 99, we get 4 and a remainder of 25.
The number 4 becomes the next digit in our result. 
Result so far: 434.0
Subtracting 396 from 421 leaves us with 25.
Take the next digit (2) from the dividend and append it to 25, then repeat: 252 / 99

Advancing to step 6:
99 can be fit into 252 2 times, resulting in a remainder of 54.
Use 2 as the next digit of our solution. 
Result so far: 4342.0
Subtracting 198 from 252 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Let's proceed to step 7:
99 goes into 540 5 times with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 4342.5
The remainder is 45 after subtracting 495 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 8:
450 divided by 99 is 4 with a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 4342.54
Subtract 396 from 450 to get 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Step 9:
When dividing 540 by 99, we get 5 with a remainder of 45.
Record the quotient 5 as the next digit in the result. 
Result so far: 4342.545
If we subtract 495 from 540, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Advancing to step 10:
If we divide 450 by 99, we get 4 and a remainder of 54.
Use 4 as the next digit of our solution. 
Result so far: 4342.5454
The remainder is 54 after subtracting 396 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 11:
99 can be fit into 540 5 times, resulting in a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 4342.54545
If we subtract 495 from 540, we get 45.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Let's proceed to step 12:
The number 99 fits into 450 4 times, leaving a remainder of 54.
Write down 4 as next digit of the result. 
Result so far: 4342.545454
The remainder is 54 after subtracting 396 from 450.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

On to step 13:
When dividing 540 by 99, we get 5 with a remainder of 45.
Put 5 as the next digit of the answer. 
Result so far: 4342.5454545
The remainder is 45 after subtracting 495 from 540.
Since there are no more digits in the dividend, we add a zero to the remainder making it 450, and continue the process.

Going ahead to step 14:
If we divide 450 by 99, we get 4 and a remainder of 54.
Record the quotient 4 as the next digit in the result. 
Result so far: 4342.54545454
Subtracting 396 from 450 leaves us with 54.
Since there are no more digits in the dividend, we add a zero to the remainder making it 540, and continue the process.

Our division results in 4342.54545454 with a remaining 5.4e-08.
