We divide 277899 by 21
We're looking to find how many times 21 goes into 277899.

On to step 1:
The number 21 fits into 2 0 times, leaving a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 2 after subtracting 0 from 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 21

Going ahead to step 2:
21 can be fit into 27 1 times, resulting in a remainder of 6.
Write down 1 as next digit of the result. 
Result so far: 1.0
If we subtract 21 from 27, we get 6.
Bring next digit (7) of the dividend behind the 6 and repeat the process: 67 / 21

Moving on to step 3:
The number 21 fits into 67 3 times, leaving a remainder of 4.
Use 3 as the next digit of our solution. 
Result so far: 13.0
If we take 63 away from 67, we end up with 4.
Append the next digit (8) from the dividend to 4 and continue with: 48 / 21

Step 4:
48 divided by 21 is 2 with a remainder of 6.
Write down 2 as next digit of the result. 
Result so far: 132.0
The remainder is 6 after subtracting 42 from 48.
Grab the next digit (9) from the dividend, add it to 6, then carry on: 69 / 21

Going ahead to step 5:
21 can be fit into 69 3 times, resulting in a remainder of 6.
The number 3 becomes the next digit in our result. 
Result so far: 1323.0
If we subtract 63 from 69, we get 6.
Append the next digit (9) from the dividend to 6 and continue with: 69 / 21

Let's proceed to step 6:
The number 21 fits into 69 3 times, leaving a remainder of 6.
Use 3 as the next digit of our solution. 
Result so far: 13233.0
The remainder is 6 after subtracting 63 from 69.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

On to step 7:
If we divide 60 by 21, we get 2 and a remainder of 18.
The number 2 becomes the next digit in our result. 
Result so far: 13233.2
If we subtract 42 from 60, 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.

Advancing to step 8:
21 goes into 180 8 times with a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 13233.28
The remainder is 12 after subtracting 168 from 180.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

Advancing to step 9:
If we divide 120 by 21, we get 5 and a remainder of 15.
Write down 5 as next digit of the result. 
Result so far: 13233.285
If we take 105 away from 120, we end up with 15.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Step 10:
21 goes into 150 7 times with a remainder of 3.
Use 7 as the next digit of our solution. 
Result so far: 13233.2857
Subtracting 147 from 150 leaves us with 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

On to step 11:
21 goes into 30 1 times with a remainder of 9.
Record the quotient 1 as the next digit in the result. 
Result so far: 13233.28571
If we take 21 away from 30, we end up with 9.
Since there are no more digits in the dividend, we add a zero to the remainder making it 90, and continue the process.

Step 12:
If we divide 90 by 21, we get 4 and a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 13233.285714
The remainder is 6 after subtracting 84 from 90.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Going ahead to step 13:
If we divide 60 by 21, we get 2 and a remainder of 18.
Use 2 as the next digit of our solution. 
Result so far: 13233.2857142
If we take 42 away from 60, 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.

On to step 14:
21 goes into 180 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 13233.28571428
If we subtract 168 from 180, we get 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

In conclusion, the division gives 13233.28571428 with a balance of 1.2e-08.
