272522 ÷ 21 
We want to figure out the number of times 272522 can be divided by 21.

Advancing to step 1:
21 can be fit into 2 0 times, resulting in a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Grab the next digit (7) from the dividend, add it to 2, then carry on: 27 / 21

On to step 2:
When dividing 27 by 21, we get 1 with a remainder of 6.
The number 1 becomes the next digit in our result. 
Result so far: 1.0
Subtract 21 from 27 to get 6.
Fetch the next digit (2) from the dividend, attach it to 6 and continue: 62 / 21

Advancing to step 3:
The number 21 fits into 62 2 times, leaving a remainder of 20.
The next digit of our result is 2. 
Result so far: 12.0
Subtracting 42 from 62 leaves us with 20.
Take the next digit (5) from the dividend and append it to 20, then repeat: 205 / 21

On to step 4:
21 goes into 205 9 times with a remainder of 16.
Write down 9 as next digit of the result. 
Result so far: 129.0
Subtract 189 from 205 to get 16.
Bring next digit (2) of the dividend behind the 16 and repeat the process: 162 / 21

Step 5:
When dividing 162 by 21, we get 7 with a remainder of 15.
Record the quotient 7 as the next digit in the result. 
Result so far: 1297.0
If we subtract 147 from 162, we get 15.
Bring next digit (2) of the dividend behind the 15 and repeat the process: 152 / 21

Moving on to step 6:
When dividing 152 by 21, we get 7 with a remainder of 5.
Put 7 as the next digit of the answer. 
Result so far: 12977.0
If we subtract 147 from 152, we get 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 7:
21 can be fit into 50 2 times, resulting in a remainder of 8.
Write down 2 as next digit of the result. 
Result so far: 12977.2
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 8:
When dividing 80 by 21, we get 3 with a remainder of 17.
Use 3 as the next digit of our solution. 
Result so far: 12977.23
The remainder is 17 after subtracting 63 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

Step 9:
If we divide 170 by 21, we get 8 and a remainder of 2.
Record the quotient 8 as the next digit in the result. 
Result so far: 12977.238
Subtracting 168 from 170 leaves us 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.

Moving on to step 10:
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: 12977.238
The remainder is 20 after subtracting 0 from 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Let's proceed to step 11:
21 can be fit into 200 9 times, resulting in a remainder of 11.
Write down 9 as next digit of the result. 
Result so far: 12977.23809
If we subtract 189 from 200, we get 11.
Since there are no more digits in the dividend, we add a zero to the remainder making it 110, and continue the process.

Let's proceed to step 12:
The number 21 fits into 110 5 times, leaving a remainder of 5.
The number 5 becomes the next digit in our result. 
Result so far: 12977.238095
If we take 105 away from 110, we end up with 5.
Since there are no more digits in the dividend, we add a zero to the remainder making it 50, and continue the process.

Advancing to step 13:
21 can be fit into 50 2 times, resulting in a remainder of 8.
Use 2 as the next digit of our solution. 
Result so far: 12977.2380952
If we take 42 away from 50, we end up with 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 14:
If we divide 80 by 21, we get 3 and a remainder of 17.
The next digit of our result is 3. 
Result so far: 12977.23809523
The remainder is 17 after subtracting 63 from 80.
Since there are no more digits in the dividend, we add a zero to the remainder making it 170, and continue the process.

The final result is 12977.23809523 with a remainder of 1.7e-08.
