We look at the division of 212723 by 99 
We want to figure out the number of times 212723 can be divided by 99.

On to step 1:
2 divided by 99 is 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 99

Advancing to step 2:
The number 99 fits into 21 0 times, leaving a remainder of 21.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 21 leaves us with 21.
Append the next digit (2) from the dividend to 21 and continue with: 212 / 99

Step 3:
99 can be fit into 212 2 times, resulting in a remainder of 14.
Write down 2 as next digit of the result. 
Result so far: 2.0
If we take 198 away from 212, we end up with 14.
Include the next digit (7) from the dividend after 14, then repeat: 147 / 99

Moving on to step 4:
The number 99 fits into 147 1 times, leaving a remainder of 48.
Put 1 as the next digit of the answer. 
Result so far: 21.0
Subtract 99 from 147 to get 48.
Bring next digit (2) of the dividend behind the 48 and repeat the process: 482 / 99

Advancing to step 5:
482 divided by 99 is 4 with a remainder of 86.
Put 4 as the next digit of the answer. 
Result so far: 214.0
The remainder is 86 after subtracting 396 from 482.
Fetch the next digit (3) from the dividend, attach it to 86 and continue: 863 / 99

Moving on to step 6:
If we divide 863 by 99, we get 8 and a remainder of 71.
Write down 8 as next digit of the result. 
Result so far: 2148.0
Subtracting 792 from 863 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.

Let's proceed to step 7:
If we divide 710 by 99, we get 7 and a remainder of 17.
Put 7 as the next digit of the answer. 
Result so far: 2148.7
If we take 693 away from 710, we end up 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 8:
If we divide 170 by 99, we get 1 and a remainder of 71.
Record the quotient 1 as the next digit in the result. 
Result so far: 2148.71
Subtract 99 from 170 to 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 9:
99 goes into 710 7 times with a remainder of 17.
Use 7 as the next digit of our solution. 
Result so far: 2148.717
If we take 693 away from 710, we end up 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 10:
The number 99 fits into 170 1 times, leaving a remainder of 71.
Write down 1 as next digit of the result. 
Result so far: 2148.7171
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.

Let's proceed to step 11:
If we divide 710 by 99, we get 7 and a remainder of 17.
Write down 7 as next digit of the result. 
Result so far: 2148.71717
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:
99 goes into 170 1 times with a remainder of 71.
Put 1 as the next digit of the answer. 
Result so far: 2148.717171
Deduct 99 from 170 and we're left 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.

On to step 13:
When dividing 710 by 99, we get 7 with a remainder of 17.
The next digit of our result is 7. 
Result so far: 2148.7171717
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.

Let's proceed to step 14:
The number 99 fits into 170 1 times, leaving a remainder of 71.
The next digit of our result is 1. 
Result so far: 2148.71717171
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.

The final outcome is 2148.71717171, with a leftover of 7.1e-08.
