We look at the division of 435879 by 99 
Our goal is to divide 435879 by 99.

Going ahead to step 1:
4 divided by 99 is 0 with a remainder of 4.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Fetch the next digit (3) from the dividend, attach it to 4 and continue: 43 / 99

Let's proceed to step 2:
43 divided by 99 is 0 with a remainder of 43.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 43 to get 43.
Include the next digit (5) from the dividend after 43, then repeat: 435 / 99

Going ahead to step 3:
The number 99 fits into 435 4 times, leaving a remainder of 39.
The number 4 becomes the next digit in our result. 
Result so far: 4.0
If we take 396 away from 435, we end up with 39.
Grab the next digit (8) from the dividend, add it to 39, then carry on: 398 / 99

On to step 4:
When dividing 398 by 99, we get 4 with a remainder of 2.
Use 4 as the next digit of our solution. 
Result so far: 44.0
Subtracting 396 from 398 leaves us with 2.
Take the next digit (7) from the dividend and append it to 2, then repeat: 27 / 99

Advancing to step 5:
If we divide 27 by 99, we get 0 and a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 440.0
If we subtract 0 from 27, we get 27.
Take the next digit (9) from the dividend and append it to 27, then repeat: 279 / 99

Going ahead to step 6:
The number 99 fits into 279 2 times, leaving a remainder of 81.
Put 2 as the next digit of the answer. 
Result so far: 4402.0
Deduct 198 from 279 and we're left with 81.

Step 7:
The number 99 fits into 810 8 times, leaving a remainder of 18.
The number 8 becomes the next digit in our result. 
Result so far: 4402.8
If we take 792 away from 810, we end up with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 8:
99 goes into 180 1 times with a remainder of 81.
Put 1 as the next digit of the answer. 
Result so far: 4402.81
If we take 99 away from 180, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

On to step 9:
99 can be fit into 810 8 times, resulting in a remainder of 18.
Use 8 as the next digit of our solution. 
Result so far: 4402.818
Deduct 792 from 810 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 10:
If we divide 180 by 99, we get 1 and a remainder of 81.
Put 1 as the next digit of the answer. 
Result so far: 4402.8181
If we take 99 away from 180, we end up with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Advancing to step 11:
810 divided by 99 is 8 with a remainder of 18.
Put 8 as the next digit of the answer. 
Result so far: 4402.81818
If we subtract 792 from 810, we get 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Going ahead to step 12:
The number 99 fits into 180 1 times, leaving a remainder of 81.
Use 1 as the next digit of our solution. 
Result so far: 4402.818181
Subtracting 99 from 180 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

Going ahead to step 13:
The number 99 fits into 810 8 times, leaving a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 4402.8181818
Deduct 792 from 810 and we're left with 18.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Step 14:
99 goes into 180 1 times with a remainder of 81.
Use 1 as the next digit of our solution. 
Result so far: 4402.81818181
Subtracting 99 from 180 leaves us with 81.
Since there are no more digits in the dividend, we add a zero to the remainder making it 810, and continue the process.

The final outcome is 4402.81818181, with a leftover of 8.1e-08.
