We're dividing 212790 by 99 
Our goal is to divide 212790 by 99.

Let's proceed to step 1:
99 goes into 2 0 times with a remainder of 2.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Grab the next digit (1) from the dividend, add it to 2, then carry on: 21 / 99

Step 2:
99 goes into 21 0 times with a remainder of 21.
Use 0 as the next digit of our solution. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Fetch the next digit (2) from the dividend, attach it to 21 and continue: 212 / 99

Step 3:
If we divide 212 by 99, we get 2 and a remainder of 14.
The number 2 becomes the next digit in our result. 
Result so far: 2.0
If we subtract 198 from 212, we get 14.
Append the next digit (7) from the dividend to 14 and continue with: 147 / 99

Going ahead to step 4:
147 divided by 99 is 1 with a remainder of 48.
Record the quotient 1 as the next digit in the result. 
Result so far: 21.0
Subtracting 99 from 147 leaves us with 48.
Append the next digit (9) from the dividend to 48 and continue with: 489 / 99

On to step 5:
If we divide 489 by 99, we get 4 and a remainder of 93.
The next digit of our result is 4. 
Result so far: 214.0
Subtracting 396 from 489 leaves us with 93.
Fetch the next digit (0) from the dividend, attach it to 93 and continue: 930 / 99

Step 6:
If we divide 930 by 99, we get 9 and a remainder of 39.
The next digit of our result is 9. 
Result so far: 2149.0
Subtract 891 from 930 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Moving on to step 7:
390 divided by 99 is 3 with a remainder of 93.
The number 3 becomes the next digit in our result. 
Result so far: 2149.3
The remainder is 93 after subtracting 297 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Let's proceed to step 8:
99 goes into 930 9 times with a remainder of 39.
Put 9 as the next digit of the answer. 
Result so far: 2149.39
Subtract 891 from 930 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 9:
The number 99 fits into 390 3 times, leaving a remainder of 93.
Use 3 as the next digit of our solution. 
Result so far: 2149.393
The remainder is 93 after subtracting 297 from 390.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Let's proceed to step 10:
If we divide 930 by 99, we get 9 and a remainder of 39.
Write down 9 as next digit of the result. 
Result so far: 2149.3939
Subtract 891 from 930 to get 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Step 11:
When dividing 390 by 99, we get 3 with a remainder of 93.
Write down 3 as next digit of the result. 
Result so far: 2149.39393
If we take 297 away from 390, we end up with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Advancing to step 12:
99 can be fit into 930 9 times, resulting in a remainder of 39.
The next digit of our result is 9. 
Result so far: 2149.393939
Subtracting 891 from 930 leaves us with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

Let's proceed to step 13:
The number 99 fits into 390 3 times, leaving a remainder of 93.
The number 3 becomes the next digit in our result. 
Result so far: 2149.3939393
If we take 297 away from 390, we end up with 93.
Since there are no more digits in the dividend, we add a zero to the remainder making it 930, and continue the process.

Going ahead to step 14:
The number 99 fits into 930 9 times, leaving a remainder of 39.
Use 9 as the next digit of our solution. 
Result so far: 2149.39393939
Deduct 891 from 930 and we're left with 39.
Since there are no more digits in the dividend, we add a zero to the remainder making it 390, and continue the process.

After the division, we end up with 2149.39393939 and a remainder of 3.9e-08.
