275925 divided by 21 
Our goal is to divide 275925 by 21.

Moving 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
Deduct 0 from 2 and we're left with 2.
Fetch the next digit (7) from the dividend, attach it to 2 and continue: 27 / 21

Step 2:
When dividing 27 by 21, we get 1 with a remainder of 6.
Use 1 as the next digit of our solution. 
Result so far: 1.0
The remainder is 6 after subtracting 21 from 27.
Grab the next digit (5) from the dividend, add it to 6, then carry on: 65 / 21

Moving on to step 3:
21 can be fit into 65 3 times, resulting in a remainder of 2.
Write down 3 as next digit of the result. 
Result so far: 13.0
Subtracting 63 from 65 leaves us with 2.
Fetch the next digit (9) from the dividend, attach it to 2 and continue: 29 / 21

Let's proceed to step 4:
21 goes into 29 1 times with a remainder of 8.
The number 1 becomes the next digit in our result. 
Result so far: 131.0
The remainder is 8 after subtracting 21 from 29.
Bring next digit (2) of the dividend behind the 8 and repeat the process: 82 / 21

On to step 5:
21 can be fit into 82 3 times, resulting in a remainder of 19.
The next digit of our result is 3. 
Result so far: 1313.0
If we take 63 away from 82, we end up with 19.
Fetch the next digit (5) from the dividend, attach it to 19 and continue: 195 / 21

On to step 6:
When dividing 195 by 21, we get 9 with a remainder of 6.
The number 9 becomes the next digit in our result. 
Result so far: 13139.0
If we subtract 189 from 195, we get 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Advancing to step 7:
The number 21 fits into 60 2 times, leaving a remainder of 18.
The next digit of our result is 2. 
Result so far: 13139.2
The remainder is 18 after subtracting 42 from 60.
Since there are no more digits in the dividend, we add a zero to the remainder making it 180, and continue the process.

Let's proceed to step 8:
21 goes into 180 8 times with a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 13139.28
Subtract 168 from 180 to 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.

Let's proceed to step 9:
21 goes into 120 5 times with a remainder of 15.
Use 5 as the next digit of our solution. 
Result so far: 13139.285
Deduct 105 from 120 and we're left 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.

Moving on to step 10:
21 goes into 150 7 times with a remainder of 3.
Put 7 as the next digit of the answer. 
Result so far: 13139.2857
Subtract 147 from 150 to get 3.
Since there are no more digits in the dividend, we add a zero to the remainder making it 30, and continue the process.

Step 11:
If we divide 30 by 21, we get 1 and a remainder of 9.
The next digit of our result is 1. 
Result so far: 13139.28571
If we subtract 21 from 30, we get 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:
When dividing 90 by 21, we get 4 with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 13139.285714
Deduct 84 from 90 and we're left with 6.
Since there are no more digits in the dividend, we add a zero to the remainder making it 60, and continue the process.

Let's proceed to step 13:
21 can be fit into 60 2 times, resulting in a remainder of 18.
Write down 2 as next digit of the result. 
Result so far: 13139.2857142
Subtract 42 from 60 to 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.

Step 14:
The number 21 fits into 180 8 times, leaving a remainder of 12.
The number 8 becomes the next digit in our result. 
Result so far: 13139.28571428
Subtracting 168 from 180 leaves us with 12.
Since there are no more digits in the dividend, we add a zero to the remainder making it 120, and continue the process.

The quotient of the division is 13139.28571428, and the remainder is 1.2e-08.
