277596 ÷ 21 
Let's see how many times 21 fits into 277596.

Let's proceed to step 1:
When dividing 2 by 21, we get 0 with a remainder of 2.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Append the next digit (7) from the dividend to 2 and continue with: 27 / 21

Step 2:
If we divide 27 by 21, we get 1 and a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
If we take 21 away from 27, we end up with 6.
Include the next digit (7) from the dividend after 6, then repeat: 67 / 21

Going ahead to step 3:
21 goes into 67 3 times with a remainder of 4.
Put 3 as the next digit of the answer. 
Result so far: 13.0
If we take 63 away from 67, we end up with 4.
Bring next digit (5) of the dividend behind the 4 and repeat the process: 45 / 21

Moving on to step 4:
When dividing 45 by 21, we get 2 with a remainder of 3.
The next digit of our result is 2. 
Result so far: 132.0
The remainder is 3 after subtracting 42 from 45.
Append the next digit (9) from the dividend to 3 and continue with: 39 / 21

Moving on to step 5:
21 can be fit into 39 1 times, resulting in a remainder of 18.
Put 1 as the next digit of the answer. 
Result so far: 1321.0
If we take 21 away from 39, we end up with 18.
Grab the next digit (6) from the dividend, add it to 18, then carry on: 186 / 21

Let's proceed to step 6:
When dividing 186 by 21, we get 8 with a remainder of 18.
Write down 8 as next digit of the result. 
Result so far: 13218.0
If we take 168 away from 186, 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.

Advancing to step 7:
If we divide 180 by 21, we get 8 and a remainder of 12.
Put 8 as the next digit of the answer. 
Result so far: 13218.8
Deduct 168 from 180 and we're left 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.

Going ahead to step 8:
21 can be fit into 120 5 times, resulting in a remainder of 15.
The next digit of our result is 5. 
Result so far: 13218.85
The remainder is 15 after subtracting 105 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

Let's proceed to step 9:
The number 21 fits into 150 7 times, leaving a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 13218.857
Deduct 147 from 150 and we're left 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.

Going ahead to step 10:
The number 21 fits into 30 1 times, leaving a remainder of 9.
The next digit of our result is 1. 
Result so far: 13218.8571
Subtract 21 from 30 to 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.

On to step 11:
21 goes into 90 4 times with a remainder of 6.
Write down 4 as next digit of the result. 
Result so far: 13218.85714
Subtracting 84 from 90 leaves us 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 12:
21 goes into 60 2 times with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 13218.857142
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 13:
If we divide 180 by 21, we get 8 and a remainder of 12.
Use 8 as the next digit of our solution. 
Result so far: 13218.8571428
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.

Let's proceed to step 14:
21 goes into 120 5 times with a remainder of 15.
Record the quotient 5 as the next digit in the result. 
Result so far: 13218.85714285
The remainder is 15 after subtracting 105 from 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 150, and continue the process.

The final result is 13218.85714285 with a remainder of 1.5e-08.
