We divide 21705 by 99
We're looking to find how many times 99 goes into 21705.

Let's proceed to step 1:
99 can be fit into 2 0 times, resulting in a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Bring next digit (1) of the dividend behind the 2 and repeat the process: 21 / 99

On to step 2:
The number 99 fits into 21 0 times, leaving a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
If we take 0 away from 21, we end up with 21.
Grab the next digit (7) from the dividend, add it to 21, then carry on: 217 / 99

Moving on to step 3:
When dividing 217 by 99, we get 2 with a remainder of 19.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 19 after subtracting 198 from 217.
Bring next digit (0) of the dividend behind the 19 and repeat the process: 190 / 99

Going ahead to step 4:
If we divide 190 by 99, we get 1 and a remainder of 91.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Deduct 99 from 190 and we're left with 91.
Bring next digit (5) of the dividend behind the 91 and repeat the process: 915 / 99

Advancing to step 5:
99 goes into 915 9 times with a remainder of 24.
Use 9 as the next digit of our solution. 
Result so far: 219.0
Subtracting 891 from 915 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 6:
99 goes into 240 2 times with a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 219.2
If we subtract 198 from 240, we get 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Advancing to step 7:
420 divided by 99 is 4 with a remainder of 24.
The next digit of our result is 4. 
Result so far: 219.24
The remainder is 24 after subtracting 396 from 420.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Let's proceed to step 8:
99 can be fit into 240 2 times, resulting in a remainder of 42.
Record the quotient 2 as the next digit in the result. 
Result so far: 219.242
If we take 198 away from 240, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Going ahead to step 9:
When dividing 420 by 99, we get 4 with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 219.2424
Subtracting 396 from 420 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 10:
99 can be fit into 240 2 times, resulting in a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 219.24242
Subtracting 198 from 240 leaves us with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

Step 11:
99 goes into 420 4 times with a remainder of 24.
The number 4 becomes the next digit in our result. 
Result so far: 219.242424
Subtracting 396 from 420 leaves us with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

Advancing to step 12:
When dividing 240 by 99, we get 2 with a remainder of 42.
Use 2 as the next digit of our solution. 
Result so far: 219.2424242
If we take 198 away from 240, we end up with 42.
Since there are no more digits in the dividend, we add a zero to the remainder making it 420, and continue the process.

On to step 13:
420 divided by 99 is 4 with a remainder of 24.
Write down 4 as next digit of the result. 
Result so far: 219.24242424
If we take 396 away from 420, we end up with 24.
Since there are no more digits in the dividend, we add a zero to the remainder making it 240, and continue the process.

The final outcome is 219.24242424, with a leftover of 2.4e-08.
