We look at the division of 21650 by 42 
We want to divide 21650 by 42.

Going ahead to step 1:
When dividing 2 by 42, we get 0 with a remainder of 2.
The next digit of our result is 0. 
Result so far: 0.0
If we take 0 away from 2, we end up with 2.
Fetch the next digit (1) from the dividend, attach it to 2 and continue: 21 / 42

Step 2:
The number 42 fits into 21 0 times, leaving a remainder of 21.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
The remainder is 21 after subtracting 0 from 21.
Include the next digit (6) from the dividend after 21, then repeat: 216 / 42

On to step 3:
When dividing 216 by 42, we get 5 with a remainder of 6.
The next digit of our result is 5. 
Result so far: 5.0
If we subtract 210 from 216, we get 6.
Append the next digit (5) from the dividend to 6 and continue with: 65 / 42

Advancing to step 4:
When dividing 65 by 42, we get 1 with a remainder of 23.
Put 1 as the next digit of the answer. 
Result so far: 51.0
Subtracting 42 from 65 leaves us with 23.
Grab the next digit (0) from the dividend, add it to 23, then carry on: 230 / 42

Step 5:
42 can be fit into 230 5 times, resulting in a remainder of 20.
Use 5 as the next digit of our solution. 
Result so far: 515.0
Subtract 210 from 230 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Advancing to step 6:
If we divide 200 by 42, we get 4 and a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 515.4
If we subtract 168 from 200, we get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

On to step 7:
320 divided by 42 is 7 with a remainder of 26.
Record the quotient 7 as the next digit in the result. 
Result so far: 515.47
Subtract 294 from 320 to get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

Step 8:
260 divided by 42 is 6 with a remainder of 8.
Put 6 as the next digit of the answer. 
Result so far: 515.476
The remainder is 8 after subtracting 252 from 260.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Moving on to step 9:
42 goes into 80 1 times with a remainder of 38.
The number 1 becomes the next digit in our result. 
Result so far: 515.4761
Subtract 42 from 80 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Moving on to step 10:
380 divided by 42 is 9 with a remainder of 2.
The next digit of our result is 9. 
Result so far: 515.47619
Subtract 378 from 380 to get 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Let's proceed to step 11:
42 goes into 20 0 times with a remainder of 20.
Record the quotient 0 as the next digit in the result. 
Result so far: 515.47619
If we take 0 away from 20, we end up with 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

On to step 12:
If we divide 200 by 42, we get 4 and a remainder of 32.
The number 4 becomes the next digit in our result. 
Result so far: 515.4761904
Subtract 168 from 200 to get 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Moving on to step 13:
320 divided by 42 is 7 with a remainder of 26.
The number 7 becomes the next digit in our result. 
Result so far: 515.47619047
If we subtract 294 from 320, we get 26.
Since there are no more digits in the dividend, we add a zero to the remainder making it 260, and continue the process.

The final result is 515.47619047 with a remainder of 2.6e-08.
