Let's divide 226291 by 21
Let's see how many times 21 fits into 226291.

Going ahead to step 1:
If we divide 2 by 21, we get 0 and a remainder of 2.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Bring next digit (2) of the dividend behind the 2 and repeat the process: 22 / 21

Going ahead to step 2:
If we divide 22 by 21, we get 1 and a remainder of 1.
Record the quotient 1 as the next digit in the result. 
Result so far: 1.0
If we subtract 21 from 22, we get 1.
Take the next digit (6) from the dividend and append it to 1, then repeat: 16 / 21

Step 3:
21 can be fit into 16 0 times, resulting in a remainder of 16.
Record the quotient 0 as the next digit in the result. 
Result so far: 10.0
The remainder is 16 after subtracting 0 from 16.
Take the next digit (2) from the dividend and append it to 16, then repeat: 162 / 21

Let's proceed to step 4:
The number 21 fits into 162 7 times, leaving a remainder of 15.
Put 7 as the next digit of the answer. 
Result so far: 107.0
Subtract 147 from 162 to get 15.
Take the next digit (9) from the dividend and append it to 15, then repeat: 159 / 21

Moving on to step 5:
If we divide 159 by 21, we get 7 and a remainder of 12.
Write down 7 as next digit of the result. 
Result so far: 1077.0
The remainder is 12 after subtracting 147 from 159.
Grab the next digit (1) from the dividend, add it to 12, then carry on: 121 / 21

Moving on to step 6:
The number 21 fits into 121 5 times, leaving a remainder of 16.
Put 5 as the next digit of the answer. 
Result so far: 10775.0
If we take 105 away from 121, we end up with 16.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Step 7:
21 can be fit into 160 7 times, resulting in a remainder of 13.
Write down 7 as next digit of the result. 
Result so far: 10775.7
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.

Moving on to step 8:
21 can be fit into 130 6 times, resulting in a remainder of 4.
Put 6 as the next digit of the answer. 
Result so far: 10775.76
If we subtract 126 from 130, we get 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 9:
The number 21 fits into 40 1 times, leaving a remainder of 19.
Write down 1 as next digit of the result. 
Result so far: 10775.761
Subtract 21 from 40 to get 19.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 10:
190 divided by 21 is 9 with a remainder of 1.
Use 9 as the next digit of our solution. 
Result so far: 10775.7619
Deduct 189 from 190 and we're left 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.

Let's proceed to step 11:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Put 0 as the next digit of the answer. 
Result so far: 10775.7619
If we take 0 away from 10, we end up with 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 12:
21 goes into 100 4 times with a remainder of 16.
The next digit of our result is 4. 
Result so far: 10775.761904
The remainder is 16 after subtracting 84 from 100.
Since there are no more digits in the dividend, we add a zero to the remainder making it 160, and continue the process.

Going ahead to step 13:
If we divide 160 by 21, we get 7 and a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 10775.7619047
If we subtract 147 from 160, we 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 14:
21 goes into 130 6 times with a remainder of 4.
The next digit of our result is 6. 
Result so far: 10775.76190476
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.

The quotient of the division is 10775.76190476, and the remainder is 4e-09.
