We're dividing 602236 by 21 
We want to divide 602236 by 21.

Moving on to step 1:
21 goes into 6 0 times with a remainder of 6.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
If we take 0 away from 6, we end up with 6.
Append the next digit (0) from the dividend to 6 and continue with: 60 / 21

Moving on to step 2:
When dividing 60 by 21, we get 2 with a remainder of 18.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
Deduct 42 from 60 and we're left with 18.
Include the next digit (2) from the dividend after 18, then repeat: 182 / 21

Step 3:
21 can be fit into 182 8 times, resulting in a remainder of 14.
Write down 8 as next digit of the result. 
Result so far: 28.0
Subtract 168 from 182 to get 14.
Grab the next digit (2) from the dividend, add it to 14, then carry on: 142 / 21

On to step 4:
21 can be fit into 142 6 times, resulting in a remainder of 16.
Write down 6 as next digit of the result. 
Result so far: 286.0
Subtracting 126 from 142 leaves us with 16.
Bring next digit (3) of the dividend behind the 16 and repeat the process: 163 / 21

Going ahead to step 5:
The number 21 fits into 163 7 times, leaving a remainder of 16.
Use 7 as the next digit of our solution. 
Result so far: 2867.0
If we subtract 147 from 163, we get 16.
Grab the next digit (6) from the dividend, add it to 16, then carry on: 166 / 21

On to step 6:
The number 21 fits into 166 7 times, leaving a remainder of 19.
Put 7 as the next digit of the answer. 
Result so far: 28677.0
The remainder is 19 after subtracting 147 from 166.
Since there are no more digits in the dividend, we add a zero to the remainder making it 190, and continue the process.

Step 7:
21 goes into 190 9 times with a remainder of 1.
The next digit of our result is 9. 
Result so far: 28677.9
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.

On to step 8:
21 goes into 10 0 times with a remainder of 10.
The next digit of our result is 0. 
Result so far: 28677.9
The remainder is 10 after subtracting 0 from 10.
Since there are no more digits in the dividend, we add a zero to the remainder making it 100, and continue the process.

Going ahead to step 9:
If we divide 100 by 21, we get 4 and a remainder of 16.
The number 4 becomes the next digit in our result. 
Result so far: 28677.904
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 10:
160 divided by 21 is 7 with a remainder of 13.
The next digit of our result is 7. 
Result so far: 28677.9047
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.

On to step 11:
If we divide 130 by 21, we get 6 and a remainder of 4.
The number 6 becomes the next digit in our result. 
Result so far: 28677.90476
Subtract 126 from 130 to 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.

Let's proceed to step 12:
40 divided by 21 is 1 with a remainder of 19.
Put 1 as the next digit of the answer. 
Result so far: 28677.904761
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.

Moving on to step 13:
When dividing 190 by 21, we get 9 with a remainder of 1.
Write down 9 as next digit of the result. 
Result so far: 28677.9047619
If we subtract 189 from 190, we get 1.
Since there are no more digits in the dividend, we add a zero to the remainder making it 10, and continue the process.

On to step 14:
When dividing 10 by 21, we get 0 with a remainder of 10.
The next digit of our result is 0. 
Result so far: 28677.9047619
Subtract 0 from 10 to 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.

The final result is 28677.9047619 with a remainder of 1e-08.
