We divide 267631 by 21
We want to divide 267631 by 21.

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
If we take 0 away from 2, we end up with 2.
Fetch the next digit (6) from the dividend, attach it to 2 and continue: 26 / 21

Step 2:
21 can be fit into 26 1 times, resulting in a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
Subtracting 21 from 26 leaves us with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 21

Let's proceed to step 3:
21 goes into 57 2 times with a remainder of 15.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
The remainder is 15 after subtracting 42 from 57.
Take the next digit (6) from the dividend and append it to 15, then repeat: 156 / 21

Step 4:
21 goes into 156 7 times with a remainder of 9.
Write down 7 as next digit of the result. 
Result so far: 127.0
If we subtract 147 from 156, we get 9.
Take the next digit (3) from the dividend and append it to 9, then repeat: 93 / 21

On to step 5:
21 goes into 93 4 times with a remainder of 9.
Use 4 as the next digit of our solution. 
Result so far: 1274.0
The remainder is 9 after subtracting 84 from 93.
Fetch the next digit (1) from the dividend, attach it to 9 and continue: 91 / 21

Moving on to step 6:
21 can be fit into 91 4 times, resulting in a remainder of 7.
The number 4 becomes the next digit in our result. 
Result so far: 12744.0
If we subtract 84 from 91, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

On to step 7:
70 divided by 21 is 3 with a remainder of 7.
Put 3 as the next digit of the answer. 
Result so far: 12744.3
If we subtract 63 from 70, we get 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Moving on to step 8:
21 goes into 70 3 times with a remainder of 7.
The next digit of our result is 3. 
Result so far: 12744.33
Deduct 63 from 70 and we're left with 7.
Since there are no more digits in the dividend, we add a zero to the remainder making it 70, and continue the process.

Our division results in 12744.33 with a remaining 0.007.
