We're dividing 272786 by 21 
Our goal is to divide 272786 by 21.

On to step 1:
The number 21 fits into 2 0 times, leaving a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 2 and we're left with 2.
Bring next digit (7) of the dividend behind the 2 and repeat the process: 27 / 21

Let's proceed to step 2:
21 goes into 27 1 times with a remainder of 6.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 21 from 27, we get 6.
Bring next digit (2) of the dividend behind the 6 and repeat the process: 62 / 21

On to step 3:
21 can be fit into 62 2 times, resulting in a remainder of 20.
Use 2 as the next digit of our solution. 
Result so far: 12.0
The remainder is 20 after subtracting 42 from 62.
Take the next digit (7) from the dividend and append it to 20, then repeat: 207 / 21

Moving on to step 4:
If we divide 207 by 21, we get 9 and a remainder of 18.
Record the quotient 9 as the next digit in the result. 
Result so far: 129.0
If we take 189 away from 207, we end up with 18.
Bring next digit (8) of the dividend behind the 18 and repeat the process: 188 / 21

Going ahead to step 5:
21 goes into 188 8 times with a remainder of 20.
Use 8 as the next digit of our solution. 
Result so far: 1298.0
If we take 168 away from 188, we end up with 20.
Take the next digit (6) from the dividend and append it to 20, then repeat: 206 / 21

Moving on to step 6:
The number 21 fits into 206 9 times, leaving a remainder of 17.
Record the quotient 9 as the next digit in the result. 
Result so far: 12989.0
If we subtract 189 from 206, we get 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Going ahead to step 7:
The number 21 fits into 170 8 times, leaving a remainder of 2.
Use 8 as the next digit of our solution. 
Result so far: 12989.8
The remainder is 2 after subtracting 168 from 170.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 8:
When dividing 20 by 21, we get 0 with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 12989.8
Subtracting 0 from 20 leaves us with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 9:
21 goes into 200 9 times with a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 12989.809
The remainder is 11 after subtracting 189 from 200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Advancing to step 10:
When dividing 110 by 21, we get 5 with a remainder of 5.
Write down 5 as next digit of the result. 
Result so far: 12989.8095
The remainder is 5 after subtracting 105 from 110.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

On to step 11:
If we divide 50 by 21, we get 2 and a remainder of 8.
The number 2 becomes the next digit in our result. 
Result so far: 12989.80952
Subtract 42 from 50 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Advancing to step 12:
21 goes into 80 3 times with a remainder of 17.
Write down 3 as next digit of the result. 
Result so far: 12989.809523
Subtracting 63 from 80 leaves us with 17.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 13:
170 divided by 21 is 8 with a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 12989.8095238
Deduct 168 from 170 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Step 14:
The number 21 fits into 20 0 times, leaving a remainder of 20.
Use 0 as the next digit of our solution. 
Result so far: 12989.8095238
Deduct 0 from 20 and we're left with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

The final outcome is 12989.8095238, with a leftover of 2e-08.
