We're dividing 267436 by 21 
We want to figure out the number of times 267436 can be divided by 21.

Moving 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
Subtract 0 from 2 to get 2.
Take the next digit (6) from the dividend and append it to 2, then repeat: 26 / 21

Advancing to step 2:
If we divide 26 by 21, we get 1 and a remainder of 5.
Write down 1 as next digit of the result. 
Result so far: 1.0
Deduct 21 from 26 and we're left with 5.
Grab the next digit (7) from the dividend, add it to 5, then carry on: 57 / 21

Advancing to step 3:
When dividing 57 by 21, we get 2 with a remainder of 15.
The number 2 becomes the next digit in our result. 
Result so far: 12.0
If we take 42 away from 57, we end up with 15.
Include the next digit (4) from the dividend after 15, then repeat: 154 / 21

Advancing to step 4:
21 goes into 154 7 times with a remainder of 7.
Put 7 as the next digit of the answer. 
Result so far: 127.0
Subtracting 147 from 154 leaves us with 7.
Include the next digit (3) from the dividend after 7, then repeat: 73 / 21

Going ahead to step 5:
If we divide 73 by 21, we get 3 and a remainder of 10.
Record the quotient 3 as the next digit in the result. 
Result so far: 1273.0
The remainder is 10 after subtracting 63 from 73.
Fetch the next digit (6) from the dividend, attach it to 10 and continue: 106 / 21

Let's proceed to step 6:
When dividing 106 by 21, we get 5 with a remainder of 1.
Write down 5 as next digit of the result. 
Result so far: 12735.0
If we take 105 away from 106, we end up 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 7:
10 divided by 21 is 0 with a remainder of 10.
The number 0 becomes the next digit in our result. 
Result so far: 12735.0
Deduct 0 from 10 and we're left 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 8:
100 divided by 21 is 4 with a remainder of 16.
The next digit of our result is 4. 
Result so far: 12735.04
If we take 84 away from 100, 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.

Let's proceed to step 9:
When dividing 160 by 21, we get 7 with a remainder of 13.
Use 7 as the next digit of our solution. 
Result so far: 12735.047
If we take 147 away from 160, we end up 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.

Going ahead to step 10:
If we divide 130 by 21, we get 6 and a remainder of 4.
Record the quotient 6 as the next digit in the result. 
Result so far: 12735.0476
If we take 126 away from 130, we end up 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.

Step 11:
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: 12735.04761
If we take 21 away from 40, we end up with 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 12:
21 can be fit into 190 9 times, resulting in a remainder of 1.
Put 9 as the next digit of the answer. 
Result so far: 12735.047619
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.

Advancing to step 13:
The number 21 fits into 10 0 times, leaving a remainder of 10.
Record the quotient 0 as the next digit in the result. 
Result so far: 12735.047619
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 14:
The number 21 fits into 100 4 times, leaving a remainder of 16.
Record the quotient 4 as the next digit in the result. 
Result so far: 12735.04761904
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.

Our division results in 12735.04761904 with a remaining 1.6e-08.
