26266 divided by 21 
We're looking to find how many times 21 goes into 26266.

Advancing to step 1:
If we divide 2 by 21, we get 0 and a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 2 to get 2.
Include the next digit (6) from the dividend after 2, then repeat: 26 / 21

On to step 2:
21 goes into 26 1 times with a remainder of 5.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Deduct 21 from 26 and we're left with 5.
Append the next digit (2) from the dividend to 5 and continue with: 52 / 21

Moving on to step 3:
52 divided by 21 is 2 with a remainder of 10.
Put 2 as the next digit of the answer. 
Result so far: 12.0
If we subtract 42 from 52, we get 10.
Include the next digit (6) from the dividend after 10, then repeat: 106 / 21

Advancing to step 4:
If we divide 106 by 21, we get 5 and a remainder of 1.
Put 5 as the next digit of the answer. 
Result so far: 125.0
Subtracting 105 from 106 leaves us with 1.
Grab the next digit (6) from the dividend, add it to 1, then carry on: 16 / 21

Advancing to step 5:
16 divided by 21 is 0 with a remainder of 16.
Use 0 as the next digit of our solution. 
Result so far: 1250.0
Subtract 0 from 16 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Advancing to step 6:
If we divide 160 by 21, we get 7 and a remainder of 13.
Record the quotient 7 as the next digit in the result. 
Result so far: 1250.7
Subtracting 147 from 160 leaves us with 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Let's proceed to step 7:
21 goes into 130 6 times with a remainder of 4.
Use 6 as the next digit of our solution. 
Result so far: 1250.76
Subtracting 126 from 130 leaves us with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

Moving on to step 8:
If we divide 40 by 21, we get 1 and a remainder of 19.
The number 1 becomes the next digit in our result. 
Result so far: 1250.761
The remainder is 19 after subtracting 21 from 40.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Going ahead to step 9:
21 can be fit into 190 9 times, resulting in a remainder of 1.
Record the quotient 9 as the next digit in the result. 
Result so far: 1250.7619
Subtracting 189 from 190 leaves us with 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

Moving on to step 10:
21 can be fit into 10 0 times, resulting in a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 1250.7619
If we subtract 0 from 10, we get 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Moving on to step 11:
The number 21 fits into 100 4 times, leaving a remainder of 16.
Use 4 as the next digit of our solution. 
Result so far: 1250.761904
Subtract 84 from 100 to get 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Let's proceed to step 12:
When dividing 160 by 21, we get 7 with a remainder of 13.
Put 7 as the next digit of the answer. 
Result so far: 1250.7619047
Subtract 147 from 160 to get 13.
Since there are no more digits in the dividend, we add a zero to the remainder making it 130, and continue the process.

Advancing to step 13:
The number 21 fits into 130 6 times, leaving a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 1250.76190476
Deduct 126 from 130 and we're left with 4.
Since there are no more digits in the dividend, we add a zero to the remainder making it 40, and continue the process.

The quotient of the division is 1250.76190476, and the remainder is 4e-09.
