We're dividing 27021784 by 990 
We want to divide 27021784 by 990.

Going ahead to step 1:
990 goes into 2 0 times with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
If we subtract 0 from 2, we get 2.
Include the next digit (7) from the dividend after 2, then repeat: 27 / 990

Let's proceed to step 2:
990 can be fit into 27 0 times, resulting in a remainder of 27.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 27, we get 27.
Append the next digit (0) from the dividend to 27 and continue with: 270 / 990

Going ahead to step 3:
If we divide 270 by 990, we get 0 and a remainder of 270.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtract 0 from 270 to get 270.
Bring next digit (2) of the dividend behind the 270 and repeat the process: 2702 / 990

Advancing to step 4:
990 goes into 2702 2 times with a remainder of 722.
Put 2 as the next digit of the answer. 
Result so far: 2.0
The remainder is 722 after subtracting 1980 from 2702.
Fetch the next digit (1) from the dividend, attach it to 722 and continue: 7221 / 990

Step 5:
7221 divided by 990 is 7 with a remainder of 291.
The number 7 becomes the next digit in our result. 
Result so far: 27.0
The remainder is 291 after subtracting 6930 from 7221.
Grab the next digit (7) from the dividend, add it to 291, then carry on: 2917 / 990

Moving on to step 6:
When dividing 2917 by 990, we get 2 with a remainder of 937.
The number 2 becomes the next digit in our result. 
Result so far: 272.0
Deduct 1980 from 2917 and we're left with 937.
Grab the next digit (8) from the dividend, add it to 937, then carry on: 9378 / 990

On to step 7:
990 goes into 9378 9 times with a remainder of 468.
The next digit of our result is 9. 
Result so far: 2729.0
Deduct 8910 from 9378 and we're left with 468.
Append the next digit (4) from the dividend to 468 and continue with: 4684 / 990

Let's proceed to step 8:
The number 990 fits into 4684 4 times, leaving a remainder of 724.
The next digit of our result is 4. 
Result so far: 27294.0
Deduct 3960 from 4684 and we're left with 724.
Since there are no more digits in the dividend, we add a zero to the remainder making it 7240, and continue the process.

Advancing to step 9:
If we divide 7240 by 990, we get 7 and a remainder of 310.
Use 7 as the next digit of our solution. 
Result so far: 27294.7
Deduct 6930 from 7240 and we're left with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Going ahead to step 10:
The number 990 fits into 3100 3 times, leaving a remainder of 130.
Use 3 as the next digit of our solution. 
Result so far: 27294.73
Deduct 2970 from 3100 and we're left with 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 11:
When dividing 1300 by 990, we get 1 with a remainder of 310.
Record the quotient 1 as the next digit in the result. 
Result so far: 27294.731
If we take 990 away from 1300, we end up with 310.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Let's proceed to step 12:
990 goes into 3100 3 times with a remainder of 130.
The number 3 becomes the next digit in our result. 
Result so far: 27294.7313
If we subtract 2970 from 3100, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

Step 13:
The number 990 fits into 1300 1 times, leaving a remainder of 310.
Put 1 as the next digit of the answer. 
Result so far: 27294.73131
The remainder is 310 after subtracting 990 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 14:
The number 990 fits into 3100 3 times, leaving a remainder of 130.
The number 3 becomes the next digit in our result. 
Result so far: 27294.731313
If we subtract 2970 from 3100, we get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

On to step 15:
If we divide 1300 by 990, we get 1 and a remainder of 310.
Put 1 as the next digit of the answer. 
Result so far: 27294.7313131
The remainder is 310 after subtracting 990 from 1300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3100, and continue the process.

Step 16:
If we divide 3100 by 990, we get 3 and a remainder of 130.
Put 3 as the next digit of the answer. 
Result so far: 27294.73131313
Subtract 2970 from 3100 to get 130.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1300, and continue the process.

After the division, we end up with 27294.73131313 and a remainder of 1.3e-07.
